Get people riled up with a ridiculous price. Start a buzz (this board is helping). Let the buzz build. Cut the price for a (still silly) ridiculously priced, beat-up Jabo. Some gullible fish will bite.

If one poured molten glass in a hole (which given how small they are, would be next to impossible), the marble would be flat-topped.

That look like UV reflection, not UV reaction. Its a swirl, not a slag.

Try to not look at glass imperfections in a marble as indicators that it is handmade/transitional. Look at the whole marble.

3 inner bands. The outer bands were a separate roll after a clear gather.

I'm by no means suggesting that others may not be interested in such a service. I'm just pointing out my take on it (regardless of a possible provider).

I don't see collectors giving up the tactile dimension of owning a marble, handling it while considering purchase and display. I have experience with slabbed coins - but rare coins and comic books degrade from handling. Marbles don't. Maybe because I've been doing this a long time and learned marble grading >25 years ago before everything out there became "near mint" and damage became known as "as mades". I don't need to depend on someone else to tell me what the condition is, and I don't fancy marbles sonically welded into little plastic cubes with a piece of paper. As for the link above, I got this:

I'll go with George Pavliscak. Some if his styles aren't far off from that.

Jabo

For most of us, white isn't counted as a color.

It appears to be a flopover single ingot.

Is the surface hard, or has some 'give'?

The bead wasn't drilled. It was mandrel-wound, a common and easy modern bead making technique. Its the first flameworked bead making technique taught in basic classes. As noted earlier, the first is just a funky cats eye.

You are correct in saying that it is not a Matthews. The signature doesn't ring a bell. Obviously a tank marble. Odd speckling, the likes of which I have never seen. Two-stage frit roll done quickly without trying to cover either pole. The gold-ish color looks iridescent - and that can reflect UV light making you think its reactive when its actually reflective. Guessing its the latter. IMO there is a fair chance that its not a generally known studio (a lot of gift shop pieces come from such studios). Size?

There is a group of people interested in the vintage manufacturing process of marbles and specifically the glass. There was a rather deep study a few years ago of the dynamics of glass in liquid form and how it behaves in a glass tank. I think you'll find that glass flow in the tank is responsible for the flow you describe resulting in that flame-line pattern, instead of it oozing out of the tank and "piling up". Some of those dynamics will be influenced by the condition/age of the tank interior, and possibly some weather conditions.

Cat's Eyes are machine made. Try not to see imperfections as "pontils".

Its just fine as it is. Any attempt to clean it will degrade it.

As a Veteran - I thank you for the kind thought. I can tell you that it can be pretty isolated and lonely for a lot of our military. Some of the places that many serve are quite isolated, even desolate. And they can feel pretty much on their own, unknown and forgotten. I have visited a few of those places. Even those on established military posts overseas with 4-500 people can feel pretty isolated serving during Christmas. From firsthand experience, it can be a quiet 24-hour shift on Christmas because married (accompanied) military almost never have duty on Christmas, New Years etc. So the younger, single guys get the duty. But they are there, serving, underpaid and generally unacknowledged. To Brothers and Sisters in arms across the globe - I know your sacrifices and appreciate all that you do. Here is a Planet recognizing how widely you serve.

Yes. Thank you. Yes, the outer perimeter is all big 'Half and Half' patch experimentals. Here is another view:
