Is there a pontil on the slag? Pattern does look like it could be handgathered.

Agree on the OP being Alley. At least that's where I kept my shooter sized one (Don't see them around much, at least for me). BerryB's marble is a CAC

Looks like an unusual Petlier to me. Nice!

The clear based look extra cool

I'm kind of wondering if the marble in the original post is is some type of torch work marble. 2nd pic down has me especially thinking that way.

Very interesting. I don't doubt the experts, but would love to see how the pontil (on the other pole) looks on these examples.

I've heard those eggs are more modern and made in China but haven't seen one myself so

Very nice! Looks like a great combination of thought, time, and talent went into it. However you choose to display (wall hanger, table-top etc), make sure the glass and frame are good and sturdy. I've reinforced my wall marble display a few times (call me paranoid) since the weight can unexpectedly add up. The sound of a CRASH, followed by a bunch of marbles tumbling everywhere wasn't something I want to hear.

Look like Akro Patches to me, but the oxblood is a bit more on the purpley side (on my monitor anyway). Since the pair compliment eachother I don't mind seeing them both in one thread

That feature would prevent it from being an intentional corkscrew for most people. I'm not aware of any other manufacturers that had the technology like Akro did to make corkscrews (spinner cups, etc.) Sometimes a twisting pattern will result from a marble traveling down the rollers. I believe some of the more common examples of this came from Jabo and were referred to as "jorkscrews", since they looked kinda like corkscrews but were more of a fluke. Yours isn't a bad looking marble, the, UV, oxblood, etc are pluses. Did I miss the size?

You didn't mention a size but Akro is a good possibility

Sounds about right to me. The base glass on these are very "soft" so chip and fracture easily. Kind of a translucent white. Stripe colors include (but not limited to) blue, red, green stripes (sometimes all three at once). Then there are the black based ones, and the blue based ones etc.

I believe they're referred to as "cold roll" marks from the rollers not being at the correct temperature to smooth them out. A lot of industrial marbles had this feature (how the marble looked wasn't as important) .

Green Clambroths aren't something I've seen much of.

With machine polishing, some things to look for: -sometimes polishing will open up air bubbles that the polishing compound gets into -on handmades the pontils are usually removed -surface is very spherical and "slippery" -patterns can change (seams can open up) as noted above -colors can change (ie: oxblood) There are other things that can jump out at you, but those are the first few things for me. If it looks too good to be true, or if something seems a bit "off", have a closer look.

Yeah, MK vs. Pelt seems to be a recent hot topic so that may be part of the soft bidding.

Possibly. Oxblood is Red. Aventurine is usually in green or black. It's thought the reaction has something to do with the minerals precipitating from the glass formula/heat, etc. , many colors are possible. I'm sure one of our more experienced glassworkers here, can explain it better.

I believe that color green and oxblood happens frequently, whether intentional or formulation related. Aventurine will sparkle under direct light. In different terms: no sparkle = no aventurine (no matter what shade or color).

Looks more MK to me. Where is Galens hammer?

You're right on your First guess (not a Popeye)! Second looks like a Vitro Third is a chip and not a melted pontil

Solid as in no light shines through it? It's seen a few battles for sure

First and 3rd pic show Akro. Green one in 3rd pic is probably CAC

Nice Corkscrews, appear to be in nice shape as well. Congrats.

@Steph what are your thoughts on these? Single color, bubbly base glass (which already looked to me that way from the first pics). Pelt Bananas? I don't know much about these but would love to see some other pics

Peltier marbles share the trait of a bubbly clear base on certain examples. Bogard (and others) also. Welcome to the site by the way! A lot of knowledgeable members here I'm sure can chime in to narrow things down
