No. A diaper fold is a CAC. When a glass ingot is cut and drops to the rollers, sometimes that ingot folds over on itself. In that case it will usually form an odd pattern. The once you have is a glass flaw that cooled too quickly to round itself fully on the rollers.

Far right one is a poor exposure. It may be MK. The other 3 may be Akro. The second is a folded reject, not a "transitional". Flaws don't signal a different process.

You understand that these are new marbles - right?

I didn't attend. I saw a fair amount of the material that came out at the New Philly show shortly thereafter. Being familiar with what came out of the site in the "Wild West Days" (I visited the site multiple times and purchased from diggers) and knowing what Roger found in his early digs - the last "cleanup" was not that interesting. Judging from a dig primary investor's problem in selling what he had, I think others had a similar view. Wild West Days remnants:

Anemic MK.

It shows a sign that would suggest torch-made.

I haven't yet seen signs that would suggest that.

I'm not seeing traits of cane-cut marbles.

I'd say that a solid Mike Warnelis box of Tye Dyes is up there.

Not Raven for me.

I purchased all of them back in the Day that Gerry was making them. Most were through an well-known intermediary who sold only contemporaries. Knowing what was involved in making them, its not surprising that Gerry stopped making them. They are quite labor-intensive. You are right that maintaining symmetry during the first and last stages had to be fairly tricky.

Modern, House of Glass.

Bring on the Veiligglas!

Could be firebrick. Cullet piles could have almost any kind of junk in them.

Since its not yours, I'll critique the no-bids: 1. Bad photos. Out of focus. Distant. Poorly lit. Bidders can't get a sense of the surface wear due to the former. Core shows poorly due to the same. When all bidders have to go on to choose how much they want it, condition etc - photos matter.

I agree that Scott was a forger. I never saw any of his work that reflected mastery - and I never knew Scott to care much about mastery. I also never saw Scott (I knew him, spent time with him a fair numbers of times, bought some of his so-so fakes a few times) as having a conscience. In fact I believe that Scott absolutely reveled in stirring-the-pot by creating fakes that caused issues in the hobby. That seemed to be his greatest reward. He sold most of his work very cheaply - some at a break-even cost of gas and glass. His hyper-arguements with people were things of legends. Old timers here remember him being banned here for cause, starting his own website to continue arguments and attacks with language and the most awful things said about people's family members imaginable. Selling Peltier NLR fakes for $3.00 is telling.

Looks like Akro glass.

Do what you have to do. Paying our debts is an important matter in our lives. You know what to do.

That is a flopover single ingot.
