Shamrock Marbles

I would love to see one Shamrock--the black based ones. Oh, I have not seen one. There was a reference to a black based pearlized patch on another forum. You’ll definitely will need someone other than me for that fact check!

Thank you. Has anyone seen a double ingot?

Fire, I don’t formulate or make glass. My glass comes from various suppliers. I totally respect those that do make glass, because I understand what hurdles they face. Bullseye sells colors in both Tested Compatible 90 COE and Stained glass (not rated). Bullseye starts with a formula intended to make 90 COE Compatible glass for fusing. After the glass is melted and rolled into a sheet, they test for compatibility or fit. If it fits, then it gets their compatibility logo. If not, then they sell it as stained glass. Finally, Bullseye has a disclaimer about their 90 COE Compatible glass. They recommend the artist to do final testing in their studio. In other words, there’s no guarantee. -John

Wouldn’t argue that any glass manufacturer started with a formula. However, the result was most often different than the original intent. Happy accidents do occur. The adhesive on Post-It Notes was a serendipitous failure. *** How many base colors of PPP are known? Four? White, Blue, Green and Tan? The rare fifth with black base? *** Was there four different runs or one run with four different bases? *** Were PPP found in sets? *** Were PPP dug artifacts? *** What documented sizes are there? Did they tend to run under 5/8”? *** Is the pearl green just a variation of aventurine green? *** Henry Helmer’s formula notes are insightful. Very minute variations in components create varied results.

Pretty much anything with two colors or more was an experiment. Even if a pair of colors worked for one run, there was no guarantee that the colors would fit the next time. *** The sheen, opacity and surface texture of the green on the PPP was truly unique. Can anyone name another manufacturer with that glass? My vote that this outcome was never planned and a pure accident. *** Are there any shooter sized examples of the PPP?

Thanks for the info! Academic papers are written for a specific audience. And typically, that language and vocabulary is specific to that particular field of study. Papers, articles and journals can be a tough read. Read just one sentence and you’re asking yourself, “Okay, but what heck did that mean?” LOL. I have usually found it worth the effort to “slug through” the language and discover the writer’s insight. Again, thanks for the information!

Very nice.👍🏻 Sizes?

C’mon man! Don’t leave us hanging.

CAC peach? -John

Love ❤️ love 💕 this green! - John

A box of Hoagies or Cheesesteaks? 😃

Gregg usually sold at the now defunct Amana show. I think I saw him at the Des Moines show a few years back. Might attend the Decatur show?

Double LOL! Back in the 70’s, my Father brought a pair of dice from Vegas. They were clean, transparent with razor sharp edges. Had them for years, but they seemed to have disappeared. It wasn’t until the 80’s that I discovered 4-sided and 20-sided die in the bottom of a dungeon. 😉

Uhm, okay. https://en.m.wikipedia.org/wiki/Skittles_(sport)

I think they called the game “Skittles”. https://www.ebay.com/itm/135202480426 https://www.ebay.com/itm/116486107486

Pretty sure they are. https://marbleconnection.com/topic/29942-buddy-marbles-box-help-me-out-here/ I can’t comment on value. Congrats on your acquisition!

Welcome. Can you post some pictures of your UV marbles? There is a bunch of experience here that can help you identify quickly. The identifying curve is quite steep. It can be very frustrating and fruitless. My most favorite UV marbles are Peltier “feathered” Slags. Followed by the Akro pattern varieties. Looking forward to your continued engagement.

A Sherbet full of MK UV marbles.

I believe it counts reactions to your posts. The more posts with more reactions, then you’ll have more Reaction points. Great job!

Fantastic packaging design!

How many Peltier pee-wees would it take you to fill it?

Battery case?

Merry Christmas!!

I agree with the others leaning toward a double ingot marble. Here is a chart that shows when two single-ingots join together to form a double-ingot marble: Basically, a 9/16" marble when doubled will be about 0.709-inches diameter. ** If you watch any of the Stephen Bahr videos that show marbles being made, you can see that double-ingots are quite common. Just watch the guy with the tongs pluck out those oversized balls. Back in the day, an operator had to operate multiple machines. They didn't have time to sort, because they were busy shoveling and adjusting. Those double ingots were culled out later during sorting and packaging. Double ingots were disposed. That is why you see many from digs. ** Fun marble you have. Might be a foundational piece for collection of "marble oddities". Sincerely, John
