They are VHTF - some of them have a bit of orange in the yellow too. Here's one Ron posted in 2020. They have yellow only, maybe with some orange, and never any white.

The green and tan looks Ravenswood and the others look like Heatons, at least to me.

It's a pretty crazy looking marble.- I can't even offer a thoughtful guess as to who made it.

It may well be Akro but I probably wouldn't call it a Sparkler unless there are more colors than I'm seeing - the white filaments seem pretty fuzzy too. Having said that, it may well have wanted to be a Sparkler. 🙂

I think this is essentially a game marble with a little color that probably shouldn't really be there. And like all marbles, they usually show the same types of seams or patterning as all the other marbles from a particular maker. They are generally not considered collectible.

I agree, newer style Vitro All Reds IMO - the left one is just a little odd.

Sure looks like it to me - you'll have a hard time finding a more crystal clear transparent base glass.

Looks more like an Akro Ace to me - no UV glow from the base.

And you didn't. lol

I really do not like IDing Kokomos from photos unless it's a distinctive type that I am very familiar with. They are just so uncommon relative to Peltier that I always proceed with extreme caution. But I know you have already shown some from your collection that I am very confident about, and those cruddy looking bubble inclusions are often, but perhaps not exclusively, a Kokomo trait - just sayin'.

It is a very cool and intriguing marble but these types are definitely not my strong suit and I really have no idea where it came from. It looks hand-gathered though and the colors remind me of many Czech marbles I've seen. Could we see a straight on shot of this area? No guarantee that it will help me much though. 🙂

I am just starting to learn more about these artists and contemporary marbles so I really don't have much to say other than I think it's a fairly common style and it seems pretty well executed. Perhaps @Alan will have some ideas about who made or will be able to correct me if I said something goofy. lol

I don't think I have ever seen that kind of yellow on a MFC. Does it look like there is a pontil on the other side of the marble (opposite the "9")? A few different views might help - my first impression is it that it's from across the pond somewhere.

It's a wild one, for sure - kinda hard to get my head around it. Peltier is one option I see, and I wonder if the thin tracer line in this pic was supposed to be a fourth ribbon or if somehow the two ribbons merged into one. It would be such weird MK that I would like to rule that out. The only other option I can think of would be a very odd Akro Corkscrew that somehow swallowed part of itself in a strange way but I don't really see signs of an unusual fold anywhere either. All I can say, is that I am leaning slightly Peltier and I can't entirely explain why. Crazy marble!

I agree the base is a little different, the bubbles look more like Akro to me and I'm not sure if it contains the fine filaments associated with Realers either - it's a pretty tough call and I'm near 50/50 on it. The base on the Royals are more opaque too though, I think.

Neat bakelite board. And very few, if any, of us knew about Veiligglas production in Holland prior to Winnie @winnie (may she rest in peace) gracing us with her presence here and doing considerable research. You may want to check out her old posts for more info.

I think there is a good chance it's a Realer - the opalescence in the base has me leaning that direction.

Is the base glass translucent - they're not really giving me a Vitro vibe. Vitro Whities would either be on an opaque white base or the white and colors would be veneered on clear transparent. I'm thinking Pelt or perhaps Kokomo. Are they opalescent or do they glow under UV?

I agree - a helix would be a single continuous line spiraling around the marble - it should have two obvious ends. Also, the book is referring to glazed China (ceramic/porcelain) marbles. The ones you're showing may also be Chinas but they are unglazed.

They all look like Rainbos to me - nice Sunset on the right. Wait, how many ribbons do you count on the left one - is there one that's like a big loop?

These must be ultra rare since I have never seen them, and I still can't. 🙂

It would be helpful to see the opposite side of the patch from what you are showing. In the meantime, here's a pic of some Acme Realers to compare to . . .

In honor of Bill McCaleb, I'll post some of his little pretties . . . As I've said elsewhere, he sure knew a good one when he saw it.

It might help, or it might just be the marble, or me. 🙂

I would guess foreign on the right one, and probably the left one too. But it's really hard to make out the seams on that one so I am not 100% sure.
