Champion Furnace with the typical annealing fractures.

It appears to be a flopover ingot, so its weird. I'm leaning CAC Snotty due to the glass density and motion.

Anemic Vitro.

They were simply in a hurry. They finished off the shear point any fast way they could. What was needed was a function of how much the cane cooled in the cup by the time the shear was made. More cooling = more work/time needed.

That doesn't appear to be 'aventurine'. I'll go out on a limb and say Vacor.

Pretty interesting all the same. I've never heard of it. I looked it up and its part of the 1940 movie promo.

Pic of the Green Hornet?

I'm guessing that the one on the right is not a transparent base.

Banded Lutz. Pretty rough condition - and lutz collectors rarely want them in this condition. Est. maybe $25 on a good day.

Kids put marbles in a frying pan and fry them over heat. The rapid glass expansion fractures the marble. Most of the time it holds together unless shocked by play or heat/cold.

1. Need to see the cut line 2: Looks like a fried cat's eyes 3. Plastic - too many in one pic to easily respond. Top are Cats eyes. Solids are game marbles. 4. Fried 5. Asian 6. Cats eye 7. Clearie 8. Prob modern 9. Cats eye

I'm not a Vitro person, but it says Vitro to me.

Not bricks, no oxblood. Game marbles, absent indications otherwise.

Post a few well-focused pics with no more than a dozen marbles in each. We can start you from there.

Given I have seen some others that are essentially the same, the green was likely expected. But as I like to say - almost anything can come out of a marble machine. Note that my example was from the Akro site French Drain oxbloods cache, dug by "W". Almost all marbles from that site location were odd in some way.

Because I'm wondering whether it is similar to this (which I can accurately ID the source):

The best answer is to watch the processes and study the result. Tank work involves the construction of a cane, one layer and one step at a time. Sometimes the step is a twist or a cane/frit pick-up or pulling the cane down. The slower approach is to study and understand how a cane construction marble is made by looking at photos, perhaps Youtube videos. There are a number of types - just as in vintage handmades. Each has it's own approach to the process, but the basics are the same. Over time you can look at a piece and reverse-engineer how it was made step-by-step. The torch/cane difference is easy to pick up with some study. They are quite different. ETA: The VERY best is to to take classes at studios. I took torch lessons from Kate Fowle which were 90% bead making, but the process for handling glass at the torch is similar. I have tank experience at Wheaton and a glass studio conveniently 15 minutes from me. Both helped immeasurably - not to mention watching true professionals like Ro Purser, Geoff Beetem, Mark Matthews, Harry Besett, Josh Simpson etc. Harry Besett:

Torch: Tank (Geoff Beetem):

I'd have to see it without the backlight effect.

I'm not familiar with him so I looked him up. All of the examples of his work is torch work. The OP piece is a tank piece.

Those in the posted link are common.

The construction is fairly unremarkable. What is odd about it is that most artists wouldn't use a dark core like that. It kind of disappears. The "I" appears to be someone's signature, but not one I am familiar with.
