Hi Akroorka, and everyone😃✨ It appears to be a Japanese pinch pontil to me.

Elias, that sounds exiting! I hope to hear good news from you! 😃

@I'llhavethat1 happy to see the whole advertisement! 😃✨

I was wrong in saying a sticker but a leaflet...

@TheVacorFan, we need your help! The yellow sticker looks kind of new. The fragments read ... in der bayeris..., ....bei Coburg..., and ....neustadt.de. The last one looks like URL.

@akroorka, thank you for helping keep the conversation headed in a good direction! I now realize that my mention of the word wasn’t appropriate for this forum, even though I meant it only as a light joke. I had hoped it might bring a smile, since hearing from the deceased isn’t actually possible. I sincerely apologize if it made anyone uncomfortable. I appreciate the thoughtful discussions here and the time people devote to marble research. I agree, this kind of work requires patience, and I have a great respect for that. I’ll continue doing my part while learning from all of you. @I'llhavethat1, the photos of more original bags are helpful. I see the city name "Coburg" on the yellow sticker in the second photo. What does the whole text say?

Completely changing the subject—but just to let you know, I might not be able to visit the forum much until sometime in next week. On Saturday, May 3rd, I’ll be giving a marble talk at the Yamagata Prefectural Industrial Science Museum. The event is for ten families with children, elementary school age and up. I won’t be speaking for that long, but I’m busy with preparations, so I may be mostly offline until then. It’s currently Golden Week in Japan, a string of national holidays, and we’re right in the middle of it now. The holiday continues through Tuesday, and I plan to spend some time with my family. I’ll be back to work on Wednesday—and that day is also already fully booked until late in the evening. 😃✨ Yamagata Prefectural Industrial Science Museum: https://y-sunka.org

Hi Nantucketdink, I’ve thought about your comment for a day, and I’d like to share the basis for what I’ve been saying. Here are the points I’ve gathered so far: ① Renée Holler told me that the marbles featured on the cover of her German marble book Murmeln are from the Hopf factory. The cover photo includes wirepulls. ② Shackman poly-netted bags contain the same kind of wirepulls and have a “Made in West Germany” sticker. ③ Renée visited the Hopf factory in 1986 and witnessed marble production. This confirms that the factory was still operating at least until that time, which helps explain the “Made in West Germany” labels on Shackman bags. If Hopf was still active then, we no longer need alternative explanations—like old Veiligglas stock being repackaged in West Germany long after the company had closed. That kind of explanation now feels forced and unnecessary. ④ In 2006, cvdv visited the German Marble Museum and learned that a mesh bag containing wirepulls was dated to around 1965. This information came from the museum. ⑤ cvdv also learned from the German Marble Museum that Hopf & Hopf produced wirepulls from around 1950 to 1980. ⑥ I own one of these mesh bags. The wirepulls inside resemble the marbles shown on the Murmeln cover. Of course, what you think and believe is entirely up to you. I’ve explained everything I can in this thread, and I really don’t have anything more definitive to add. If you’re still looking for a more definitive answer, maybe the only option left is to hold a séance and ask the people who were actually there!

Hi @LevvyPoole If you found the pictures helpful, I’m happy! Big bubbles are caused when the glass stream is cooler. If the glass is soft enough, it simply accumulates in a metal cup without leaving gaps between the layers. But when the glass is cooler and harder, it tends to trap gaps. These hollow spaces then become big bubbles inside the marble. I guess lowering of temperature can happen with any maker.

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
