This morning I decided to open the mesh bag for taking pictures. 

According to cvdv (Cees), this type of bags is from around 1965, but we don't know from when to when these bags were in use for Hopf packaging. 

The paper header was stapled through 3 parts. I think I did a good job removing staple pins. The mesh felt brittle. I dealt with a care. 

"Hello, marbles! At last I see your faces clearly!😃" 

The diameters range from 18.5 to 21 mm. Most of them are spherical, but a few exceptions. 

Below are close-ups. 

Because of the white background, the white in the ribbons becomes hard to see.

The light also comes thru the ribbons. 

Because of these factors, the marbles might look a little different from how they actually appear. 🙏

We see some tiny fractures along the yellow ribbon. 

Below are Hopf wirepulls on a darker background. 

I see small bubbles along the ribbon only on the blue one. 

This group photo shows more of what my eyes actually see than close-ups. 🫧

@Da Roberto, @TheVacorFan and @LevvyPoole, the idea of comparing sounds fun. 

I also feel that it would be a good idea to start a new thread focusing on Hopf vs Veiligglas wirepulls.

Thank you, Elias and LevvyPoole, for bringing up the suggestion!

It will help keep this original thread focused on Hopf information, and allow us to organize the comparative discussion separately.

I'm looking forward to seeing everyone's wirepull examples there!

@TheVacorFan , as @Ric mentioned, one of the features that can help distinguish Hopf wirepulls would be the presence of reflections and bubbles along the stripes.

However, the examples I have from the mesh bag don’t show much of these characteristics, and the same can be said for my loose examples. I think there are some exceptions.

In the color part along the ribbon, you can sometimes find tiny white grains, very much similar to grains of sand.

These grains seem to be incompatible with the glass and cause small fractures, which in turn create the reflections.

I also notice bubbles along the ribbons in some wirepulls, but I’m not sure if they are related to the sand-like particles.

I took some pictures today, but most turned to be not good. The wirepulls below are what I found in German lots. 

@Ric Thank you, I finally reached the price list you mentioned. 🙏  

A post in "Trip to Lauscha" posted by cvdv contains important pieces of information on our topic, including the 1953 price list of Hopf &Hopf company and a 1964 wirepull mesh bag photo. It says after a trip to the Marble Museum in Lauscha, Germany, he searched for information on wirepulls. 

 

"Then The Wirepull: This marble was made by the compagnie Hopf&Hopf from Coburg-Esbach, as far as I know, this was not in East-, but in West-Germany, but very close to Thüringen.

From about 1950-1980 the wirepull was (only) made by this compagnie. The owner of the factory invented the machine by himself. Its almost sure that the wirepull was made on the same way as the Illmenaumarbles. First I didn't believe this all, but then they told me that they had some original pricelistings (is this the English word?) from the compagnie and I bought some original bags with wirepulls, made about 1965 from them. There is also a picture of two men (Hopf&Hopf?) made in the factory. I only show one pricelist, but they copied three for me.

For now, this is in short time what I found out this last year, I hope it's usefull for some of you, if I find out more, I'll share it again.

Cees."

This is a great piece of information not to be forgotten. 

 

 

@TheVacorFan Thank you for your translation, Elias! 😃🙏💕

@I'llhavethat1 I think the packaged wirepulls that were shown earlier are Hopfs. 🫧✨

@Ric It's great to see these netted bags.🫧✨ I think these wirepulls are quite common in German lots, the newer-looking wirepulls.

 I think everyone here would like to look at them out of the net.

Can you untie the open end of the bag without causing any damage for photographing?🙏 

I will shoot my loose examples in a few days and post here.

About Brilliant marbles, I don't know for sure if it is Hopf product.

The box has a trademark... do you recognize anything which makes you think that connects to Hopf?

I see something like A and E, but the A is with a design... a squirrel with a big tail?

 

I enjoyed Steph's post very much. Thank you for letting me know. Lots of photos and informative.🫧✨

One of the photos from the Marble Museum showed wirepulls in the same paper-labelled bag.

In 2022 I learned from Brian that the marble museum had artifacts from 3 of bankrupt marble companies.

One of them was H. E. Hopf. https://www.allaboutmarbles.com/viewtopic.php?p=359175&hilit=TOKU#p359175

@TheVacorFan Elias, thank you for letting me know. I understand... so it’s difficult to reach the owner of murmelwelt.de. 🥲 I hope he is alright... 

 

@Ric I’ve been interested in the Hopf factory ever since Elias and my friend translated the report for us.

This time, I was lucky to come across a YouTube video where the author tells her story, speaking in Spanish.

The book was published in 1986, so I thought Renée must be a very old lady—but it turned out she was young! 🙏✨

Then it wasn’t difficult to find her website...I sent her a message from there. 

Here is the link.   

https://marbleconnection.com/topic/39712-hopfs-wirepulls-and-more-looking-for-information/

@Fire1981 Hopf's wirepulls and more... Looking for Information!  is the new thread. Please take a look when you can. 😃 💕 ...I can't change the font size!

 

Hello @Fire1981! This is the post. Please look at the cover photo I'm going to show below. I think yours look similar.  😃

 

On April 11 2025, I sent an inquiry to Renee Holler, the author of Murmeln (1986), a German book on marbles.

The message I sent wasn’t very personal, so I share a screenshot for reference.

 

 

In 2022, Elias Fitz @TheVacorFan and my friend Helma Rud put in extra effort to translate Renee Holler's marble factory report.
They were very helpful, and they did a wonderful job. Thank you! 🙏💕

 

Holler Murmeln translation by H. Rud.

The next stop on the tour of the factory premises is the glass marble production. The machine, which the owner designed himself and which he had built according to his own sketches, is unique - a monster made of bricks and iron constructions that spits out colourful glass marbles.

After a mixture of waste glass, sand and soda has been poured into one end of the gigantic contraption, everything seems to work by itself. On its way through the machine, the mixture is melted into a viscous paste at high temperatures. At the end, the finished glass mass is pressed out of the apparatus, like toothpaste from a tube, while the clear glass is simultaneously sprinkled with liquid, colored glass from a second opening. Candy-sized pieces are then cut off from this glass paste and then fall onto a roller. They roll along the spiral-shaped surface - still wet - in order to fall, already formed into a ball, onto a second roller on which they are cooled by a fan until they finally fall into a tin bucket as finished marbles. The colored glass thread, which was sprayed onto the glass before cutting it off, is twisted into the marble by the movement of the roller while the glass is still soft, in which it can later be seen as a streak.

In the past, glass marbles were painstakingly made individually by hand. It wasn't until the middle of the 19th century that the first step towards a faster production method was made: Christian Greiner, a German glassblower, invented marble shears. With these scissors, at the ends of which two hemispherical shapes were attached instead of cutting surfaces, a strand of glass was simply cut off and the rough edges were filed off. However, only fully automatic, electrically operated machines, such as those in Dörfles-Esbach, made glass marble production a worthwhile trade. 
Nevertheless, business is declining, the machines stand still for most of the year: when children stop clicking ( = playing with marbles) , the most beautiful marbles become superfluous (unnecessary).

 

 

As for the other translation completed by Elias, we will wait for him to join us here and post his version when he can. 🙏💕

The translated texts were originally posted in my thread "Euro Stripey cats, Canadian Purple and cats from Japan!" on All About Marbles in Jan 2022.

At that time, we were searching for a possible Stripey maker in Germany. We kind of concluded that the marbles described by the author were not stripeys, but sparklers.

However, the description is very difficult to interpret.

Now I have started to think that they could have been wirepulls. 

I wish to hear the answer from the author.

===============================

On April 16, 2025, I received a reply from Renee Holler herself! 😃 What a big honor!

Since I haven't obtained permission from her yet, I won’t share a screenshot of the reply.

 

The main points of her response were as follows:

① The author’s visit to the factory was in 1986.

② Mr. Hopf, the owner of H. E. Hopf factory, showed her two ways of making marbles: clay and glass. 

    They made both clay marbles and glass marbles!

③ The method of making glass marbles was described in her book on page 19. Fully automatic. 

④ The marbles on the cover of the book were from Hopf’s factory.

⑤ No specific mention was made about the type of marbles witnessed at the factory.

 

================================

I am currently waiting for another reply from her.

On April 20, 2025, I sent a second inquiry.

This time, following a piece of advice from Elizabeth Kempski @Pinx,

I asked her to confirm whether ALL of the marbles on the cover were from Hopf’s factory.

I also shared some marble information with her as a way of showing my gratitude.

For ease of reading, I first type my message to her. This time the letters are a bit too small. Screenshots follow afterwords. 

 

"Dear Renee,

Thank you for your reply. I am very much excited to know that the marbles on the cover are Hopf's. 

It is a maker that we only knew by name. "

(Hopf stationary with 1965 date)

The stationary photo is from @akronmarbles. Thank you, Brian! 🙏💕

"Now we have a photograph of their marbles... it will become a big news to the marble fans. 

Do you know marble forums such as Marble Connection and All About Marbles?

We share knowledge on marbles and discuss there.

I have one more thing to be confirmed to you... were ALL the marbles on the cover made at

the factory?

This is important.

=============

Below are two examples that are to be Spielwaren Hopf packages. 

To my eyes, the marbles (wirepulls) match the style. "

(A netted bag of wirepulls saying Made in West Germany.)

"A poly-net bag is distributed to the American market by Shackman & Co.

An American collector Buckeye posted the photos at marble Connection in 2017."

(The same netted bag showing backside saying Shackman NY)

This plastic netted bag photos are from recent post by @Ric.🙏 💕

Thank you for both Ric and the owner @BuckEye ! 🙏🙏❤️

(A natural fiber net bag with a paper label.)

"Another example. It doesn't say anything on a paper label. 

My friend bought it for me as a gift at a Tokyo shop which specialized in vintage DDR goods.

Although they were not from East Germany, I am now honored to own these marbles.

When you know the history of the maker, even if it is a small portion, love deepens. 

Thank you for your work"

(The same paper label bag with loose matching marbles from a German lot.)

"Very best wishes and thank you, Aiko Suzuki" 

 

==========================

I believe we can identify Hopf marbles by closely looking at the photos.

The cover photo is in A4 size. It's large enough to see the details. 

Buy Renee's book while you can find!

 

I hope @akronmarbles join us and share Hopf's patent information with us when he can spare his time. 🙏✨

Also, any information about Hopf’s products or its history is welcome, please feel free to share it here.

 

 

　

@Ric  I think Euro swirls/wirepulls were made by Veiligglas, Hopf and Seike.　

I cannot think of any other names, since I don't have any proof. 

Do you happen to know any other possibilities?

It would be great if we could keep exploring these things together.😃🫧✨

@akroorka Thanks for letting me join.😃💕

I've got my boombox when I was in the 5th grade, used it for recording a voice letter to a class mate.

At night on the radio was music like Shine on TV by A-ha, Sade and Stevie Wonder. 

I listened to the radio throughout my teenage years.

A Japanese music critic, Yoichi Shibuya, often recommended artists like the Gipsy Kings and Weather Report.

Before my interest shifted more toward jazz, I listened a lot to David Bowie, The Police, and Frank Zappa.

I love the unique beautiful voice of Kate Bush... my brother had lots of her cds. 

@Fire1981 Many thanks for posting your marbles. From the newer look, I feel Hopf for these, but I am sorry if my way of seeing them is wrong. I planned to talk about Hopf marbles in near future, but if you can't wait, I can explain it here. 😃 Do you want me to do it right now?

@Ric The questions you asked are probably the ones many people here have been wanting to ask too. But I’ve already shared everything I know. I’ve spent quite a bit of time digging through the archives of Japan’s National Diet Library and Japan Patent Office. The documents I’ve mentioned are all I’ve been able to find so far. 

I suppose your question is related to wirepulls, because you are one of the owners of "foreign" Codeg boxes. Please let me explain. 

First, here are the clues I’ve got:

① Seike filed a utility model for a swirl-making device in 1936.（https://www.j-platpat.inpit.go.jp/c1801/PU/JP-S12-013819/22/ja  I would do line-to-line translation in a near future. Please remind me and request if I forget to do so. I have many things to be talked.  ）

② The Bolitas Japonesas boxes hold wirepulls.

③ In a 1937 glass industry conference, he stated that the UK was his largest customer. (Dec 1937 “Science and Industry / Kagaku-to-Kogyo” https://dl.ndl.go.jp/ja/pid/3334881/1/33 )

④ Seike’s Duck Brand Trade Map includes London, Amsterdam and another port in Europe. (“ 1951 Duck Marble advertisement for domestic market (Side A)" https://marbleconnection.com/topic/39400-1951-duck-marble-advertisement-for-domestic-market-side-a/#comment-335643)

⑤ Fairylite was a trade name used by Graham Bros., a London-based toy importer (1887 to 1970). They dealt mainly in the import and wholesale of items made in the Far East / Hong Kong. (A post by slagqueen Sep 27 2019 at AAM. https://www.allaboutmarbles.com/viewtopic.php?p=321847&hilit=Fairylite#p321847)

⑥ We see names of Graham Bros and Cowan de Groot in Japanese trading documents in 1935 and 1936 ("Ministry of Foreign Affairs Trade Bureau Daily Report No. 286", Ministry of Foreign Affairs Trade Bureau, 1935. https://dl.ndl.go.jp/ja/pid/1893946/1/360?keyword=Cown+de+Groot  & "Directory of Overseas Importers, 1936 Edition" Edited by Osaka Prefectural Trade Hall, 1936. https://dl.ndl.go.jp/ja/pid/1228204/1/35?keyword=Coran+de+Groot)

⑦ Fairylite imported toys from Japan, as seen on boxes like the “Moon Explorer,” marked “Made in Japan” with the Fairylite logo. ( A post by Alan Dec 31 2007 in Steph's "Fairylite ... German? American?" https://marbleconnection.com/topic/7707-fairylite-german-american/#comment-68004)

⑧ A Fairylite marble box marked “Foreign” includes green marbles with dark green bits—a trait found in Seike’s glass. (You can see the dark green bits in all 3 marbles from wvron's photographs ”Interesting vintage box of marbles” by wvrons Sep 27 2019 at AAM. https://www.allaboutmarbles.com/viewtopic.php?t=43695&hilit=Interesting+vintage+box+of+marbles)

⑨ “Foreign” was used to label Japanese goods in the UK due to anti-Japanese sentiment after the Manchurian massacure and during the war. (Nobuo Kumagai "The Japanese Tin Toys from 1880's to 2010's" I talked about this topic in Steph's "Fairylite ... German? American?" )

⑩ This labeling continued into the postwar years. (Nobuo Kumagai )

11   Before 1954, Hong Kong imported marbles mainly from Japan and re-exported them to Commonwealth countries. (“The Glass Marble Industry of Hong Kong” in Steph’s “New Cat’s Eye Historical Data” Apr. 29. 2009. https://marbleconnection.com/topic/11272-new-cats-eye-historical-data/#comment-95175)

 

Then a story based on my research:

When Seike began producing machine-made swirls, the type described in his 1936 patent, he also started exporting them. Many of his marbles were shipped to the UK, which had become his number one customer. To take advantage of favorable tax treatment under the Most Favored Nation status, British importers routed Japanese marbles through Hong Kong.

However, after the Manchurian Massacre in December 1937, anti-Japanese sentiment surged in Britain. Boycotts of Japanese goods began, and the labeling on products was changed from “Japan” to “Foreign.”

By the summer of 1941, exports of Japanese goods to the UK had ceased. That situation continued until the end of the war. During wartime, the Japanese government, anticipating future export potential, allowed the marble industry to survive as part of wartime industrial restructuring. Seike’s joint company continued marble production throughout the war. ( "The Industrial Readjustment for Small and Medium-Sized Businesses in Osaka; The Fact-Finding Report on the Industrial Readjustment for Small and Medium-sized Businesses Under Osaka Prefecture", The Osaka Chamber of Commerce and Industry, 1943.  https://dl.ndl.go.jp/ja/pid/1058348. I talked about this in Steph's "Fairylite ... German? American?")

This is why, immediately after the war ended, Seike was able to supply his marbles to the global market.

Here’s what the postwar European marble scene looked like:

“Since the war, the German marble manufacturing disappeared and the Netherlands only has one marble factory.
Also France still has a marble factory, but that’s all there is in Europe.
The largest marble producer is Japan.”
(From the post “Dutch Marbles Roll Over the Globe” by Winnie, May 18, 2016 https://marbleconnection.com/topic/22077-french-marbles/?do=findComment&comment=196685)

Even after the war, anti-Japanese sentiment remained. Some distributors who had handled Japanese marbles before the war began to seek alternatives, or inexpensive marbles made in other countries.

Cowan de Groot, although based in Britain, is thought to have Dutch roots by its name. After the war, he approached a glassworks in his homeland, the Netherlands. He asked if they could produce swirl-type marbles similar to the popular Japanese ones from before the war. As a result, Veiligglas began making marbles in 1949.

I believe that for them, it was crucial to emphasize that these marbles were “Made in Holland.” That phrase was printed on the boxes to differentiate their marbles from the Japanese “foreign”.

From this point, Seike's marble exports to the UK declined. I’m sure Cowan de Groot and others would not have done anything so foolish as to pack Dutch marbles into boxes labeled “foreign”—that would’ve ruined the purpose entirely.

In 1954, new tax regulations were enacted that disadvantaged Japanese marble imports. The use of “Foreign” labeling was completely banned. This change greatly reduced the appeal of importing Japanese goods via Hong Kong. Hong Kong started producing marbles, both clay and glass from this year too. Trade volume dropped, and for Seike, this must have been a serious blow. 

=============

I believe that by gathering information from many sources, we can deepen our understanding and increase the reliability of what we know.

In fact, I’d be more interested in asking the reverse questions. Do you have any documentation that shows exactly which manufacturers these distributors imported marbles from? Are there any records that clearly connect other marble makers to these toy merchants? That kind of information will be important as much as the documentation I have found out. I’d like to know what’s out there from the UK side.

@Ric I agree with you. Seike’s marbles really do show a wide variety. They are a reflection of both his passion and the times he lived through. He made marbles over a long period, facing many changes—like the depression in the early Showa era, the war, material shortages, and trade restrictions. He had his ups and downs, and all of that reflected in his marbles.

Some of his marbles are beautiful, but after the war, there are also pieces that don't look as good, due to the high content of recycled cullet. I’m not sure whether those were exported or not.

It seems that his company ceased operations around 1959. One main reason (except for his age) was a sudden surge in marble production. A newcomer to the industry, who initially knew almost nothing about marble making, struggled with his new equipment. He asked an engineer named Yasuaki Hosoi to help improve the system. Hosoi turned out to be the right man. The improved system was a great success, and other factories quickly followed. Production grew nearly tenfold in a short time. Overproduction led to a price collapse, and only a few survived. The impact was worldwide; marble makers in Europe and America also shut down. (I will post a translation of Hosoi's memoir in the near future.)

I’ve mainly collected marbles from Japan, the UK, and Germany, so I’m sure I can learn a lot from you about WV swirls. Thanks again for sharing your thoughts.

Hello everyone, it’s noon here in Japan, and I’m back on the forum.

I figured my earlier post might stir a confusion... For now, the safest approach would be to study marbles that are still in their original packaging. That’s where we can gather the most reliable clues.

For that, we’ll need the help of those who own such boxes. I need your help, @Ric. 

Once we’ve studied more, we may be able to recognize what was likely made by Veiligglas, Seike, or ... Hopf, but only by comparing them closely with well-preserved original examples. 

As for why Japanese marbles were labeled “foreign” before and after the war, Steph's thread “Fairylite... German? American?” has some good background on that. I posted about it there last year. I also talked about toy companies like Cowan de Groot and Graham Bros. in “1951 Duck Marble Advertisement for Domestic Market (Side A)”. Feel free to check them out! 

I also would like to hear from @Mojo and say hello. 

-----

@akroorka Oops! I didn't see your warning when I posted! I will delete this post on your request. 

@Ric That is a good idea.😃 @davesnothere I also look forward to the photos. 🫧✨

@akroorka when I use the term wirepull, I meant swirls that were thought to be made in Europe. 

I didn't know the definition until recently, til I read wvron's post giving the explanation.  

 

I closely looked at the photo of Dave's, enlarging it to the maximum.

My overall impression is that the group has many swirls/wirepulls with wispy striations.

 

To compare, I joined two photos. Roberto's bolitas japonesas box is on the left and Dave's wirepulls are on the right.

We see two swirls in light tan in the original box and one in Dave's. 

Below are individual photos Roberto shared with me.

They are great closeups. Have fun looking at the details. 

 

 

Here's another set of photos. This time Dave's marbles are on the left. 

Please look at the hiding marble that I circled in pink. My eyes kind of attracted to the one.  

It has a little bit of blue mixed in white.

You see this kind in a smaller bolitas japonesas box which holds only 9 marbles.

Again, the image is from Roberto. He couldn't remember which source he found it.

 

 

FYI below are some original boxes of Seike's which have "foreign" country of origin. 

I started a thread titled "Seike's 1936 Wirepull Invention" at another marble forum in 2022, where I did line-to-line translation of his utility model right.

All the photos were contributions of @Nantucketdink there.

These boxes are probably well-known to the people who are interested in wirepulls.

Some part of the consensus of Veiligglas wirepulls has been made around these boxes.

Now it is time to study these marbles one by one. 

 

At the end I share 3 marble photos from wvron.

Back then he was the owner of the bolitas japonesas box.

Marbles look a bit different when the photographer is different. 😃

 

 

 

 

 

@Ric @davesnothere Fibrous wiggles make me think they are Seike's... 

Below was my answer when I had an inquiry from @YasudaCollector some time ago. 

And also two of the local finds which also have that trait. 

 

Thanks, Dave! I feel that would be one too. The fine thread of intricate wiggles and the big bubble would point in that direction.
Identifying exactly what’s Seike is still really difficult. The world would be simple if there were only one maker, but there were at least three for Euro swirls. We really need more originals— Bolitas Japonesas, Fairylite pieces, “foreign”-marked ones, and pre-war examples, to compare with other maker's. 

@Ric Thank you so much for your comment...late or not doesn't matter! 😃I appreciate that you took the time to look so closely at the photos. It’s rewarding to know someone enjoyed them.

The marble you mentioned is one that belonged to the Fairylite box. I'm sure to pass your words to Roberto soon. He is such a generous man, he always shares his marble photos with me. 

About the development of Cat’s Eyes...back in those days, the competition among makers was intense. Creative inventions came out of rivalry, and they grew together through the competition. 

Then, there was a marble makers’ association, and the head was Isogami. He kind of represented the newcomers in the industry, while Seike was more of a pioneer and a loner. You might think Seike would naturally have taken the lead, but that wasn’t the case. The first association was actually formed by newer makers who wanted to buy color glass and other materials in bulk and split the cost. Seike, on the other hand, was independent. He ran his own factory and made everything himself, so he didn’t really need to rely on anybody.

I believe Seike eventually joined the association because the government wanted to unify the industry. When that happened, the organization became naturally divided into two groups.

Later, when wartime industry reform was first planned, the marble industry was supposed to be reduced to two factories—one run by Seike and his allies, and the other by Isogami and his group. But as Japan’s war situation and financial situation worsened, only one factory was allowed to survive. In the end, it was Seike’s side that remained, while Isogami and the others had to leave. All of the marble-making equipment and patents were passed to Seike’s group and used for marble production during the war.

 

@Ric Yes. Your observation is right, the seams are different. Yesterday I asked another marble peer the same question, and he also answered that would be Asian made. They are probably Taiwanese! 😃✨

My talk this time is about Seike's cat's eye invention.

Below is a translation of his patent article. 

 

 

Japanese Utility Model Showa 14 No.9082. 

Filing Date: March 3, 1938.

Publication Date: June 15 1939.

Applicant / Inventor: Naoyuki Seike 

Device for Mixing Colors in Glass

Summary: This utility model features a glass furnace equipped with a glass chamber (1) and an outlet (3). Positioned close to this outlet (3) is the lower end of a rotating glass feed tube (4), which functions as a passage for molten glass. One or more discharge openings (6) are drilled into the sidewall near the bottom end of the tube to release the glass. 

Article: In this invention, molten glass from the main glass chamber (1) is discharged through an outlet (3). At this discharge, the lower end of a rotating glass feed tube (4) is positioned so that a stream of colored glass can also flow out from its own outlet (6). As a result, at the point of convergence (3), the steady steam of clear molten glass from the chamber and the narrow colored stream from the rotating feed tube become integrated under a rotating motion, allowing the colored glass to spiral delicately within the main flow and be discharged in that mixed state. 

And when the discharge openings (6) are made as two or more, it becomes possible to achieve a more varied and colorful result in terms of color mixing. 

Therefore, this invention has a simple structure yet produces beautifully blended colored glass, making it highly effective for practical applications such as the manufacturing of glass marbles. 

In this invention, if necessary, the interior of the glass supply tube may be divided, allowing different colored glasses to be supplied and flow down respectively. 

*******

I think Seike was probably trying to make marbles with internal spirals, like the ones we see in old German handmade marbles, using this device. That is why he designed the inner tube to rotate. 

But to get a proper spiral inside a marble which is less than two cm across, the tube would need to spin really fast. I don't think that was possible back then, and not even today. Spinning a tube that is submerged in molten glass at high speed sounds difficult, even with modern advanced technology. 

As many of people here probably notice, the basic system here is actually the same as the one for making cat's eye marbles. After trying out this setup for numbers of times, he would eventually end up creating cat's eyes instead of spiral marbles. 

Tatsukichi isogami filed his cat's eye patent on March 11, 1938. But Seike filed his on March 3 of the same year, 8 days earlier. 

Isogami wrote about the details of the device he used to make cat's eyes in his article. Then, just two months later, on May 24, 1938, he filed another utility model. This time, it wasn't about the machine itself, but about defining the design of cat's eye marbles. 

It's not really common to first patent the device and the separately file something just to define the look of what it makes. In my opinion, he did this because Seike had already managed to make cat's eye marbles using a machine of his own design. Since Seike's utility model was filed earlier, Isogami couldn't claim Seike had copied his invention. Instead, he tried to protect the appearance of the marbles, to make sure no one else could legally make marbles of the same kind. 

I don't think Seike wanted to make the exact same kind of marbles as Isogami. Many of Seike's cat's eyes have a twist to them. That probably reflects not only his experimenting nature, but also an intention not to copy Isogami's work. 

For example, there are marbles with as many as 12 vanes, 

or with hybrid vanes in mixed colors. 

Some are hybrids, combining internal vane structure with ribbon or patch marble designs. 

Some have two-toned base glass.

Others feature jelly vanes or softly-translucent alabaster vanes. 

In some, the base glass is colored while the vanes themselves are white. I think Seike's internal vane structure actually started from here. 

Seike just kept going with his own idea and tried all sorts of new things. 

I think the cats with many vanes came after the war, but the stripey cats might have been from pre-war time to post-war periods. 

Below is an example of stripeys in a pre-war assortment of glass toys. 

 

 

 

I agree with Mojo anf Ric. 

Mine measures 25 mm, and it is with a distinct orange peel texture too. Yellow is almost disappearing. 

This is an English lot it belongs to. 

 

I wonder who made these two. The orange peel texture can be felt for them too, although the feel is subtle. 

 

 

@davesnothere @akroorka We exported glass bottles to the world in the early years. When I was searching for marble-related information, I came across to Osaka Bottle Works (Osaka Seibinsho), a manufacturer and exporter of various kinds of bottles and marbles. It was established in 1907 (Meiji 40), and once monopolized 80% of Japan’s total exports of beverage bottles. Here are some information on them. 

An advertisement of the bottle company. The circled B is their trademark. 

"Shina (China) Yearbook, Second Edition" (1917)

Edited and Published by: East Asia Common Culture Society, Research and Compilation Division

 

 

 According to "Complete Collection of Japanese Registered Trademarks, Series 7, Volume 1" (1915), the trademark was registered in April 1914. Their bottles had a B embossed on the bottom?

 

I first saw the entry of Osaka Bottle Works in connection with marbles in "Export Product Purchasing Guide, 1919–1920" . 

"Export Product Purchasing Guide, 1919–1920"

The list says the company is "the mfrs. of Glass Bottles and Glass Marbles". The Japanese reads 硝子瓶及瓶玉, or Glass Bottles and Bottle-stopper Marbles.

Under the bottle company is the name of Owi Tokujiro. He was the person who left a record of the earliest glass marble export in the country (1915), and I believe his product was toy marbles with a design. His main products were glass bangles for India, mercury beads, fake-pearls and other kinds of glass beads. 

 

Other entries which are also available in English;

 

 

 

 

 

To add something important, the proper name for the books appears to be "The Japan Mercantile & Manufacturers' Directory and Private Residents' List" by A. Cameron & Co. Ltd. I don't understand why we have double names for a book.

 

 

I also found a factory photograph!

It operates a factory covering a site area of approx. 9,900 m² (106,000 sq ft), with buildings occupying 6,600 m² (71,000 sq ft)...employing over 800 workers.

From "General History of the European Great War and Peace Commemoration: With an Appendix on the Glass Industry During the War" (1919)

 

This company was one of the leading pioneers in the bottle manufacturing industry besides Tokunaga. They introduced Siemens-type regenerative furnaces and dramatically increased production efficiency. In one month, it produces 1.5 million bottles for beer and carbonated spring water (including Ramune bottles for export), as well as 25,000 acid-resistant bottles and 250,000 perfume bottles (using crucible furnaces). Later on, Osaka Glass Bottle Works purchased a partial usage right to the Hartford-type furnace from Tokunaga, who held the exclusive rights in Japan. This advance allowed the company to shift from a system in which only raw materials were melted during the night, to a continuous operation where bottles could be produced both day and night. 

Due to the high quality of its products, the company has gained a strong reputation in markets around the world. As a result, only a small portion of its products are supplied domestically, while the remaining 90% are entirely exported—mainly to destinations such as British India, French India, the South Seas Islands, Hong Kong, Shanghai, Africa, and Great Britain.
