Nice start to the day, Dave! I'll be heading the same direction later.

I'd guess it's a sort of Skunk (Rainbo) but it looks a bit like one of those mushroom mibs too.

You really have to be careful when looking for big Alleys because JABO made quite a few that are tempting. I think this one may be from a contact run - Mamie's?? And I think if you found a 1" Blackie you'd really have something. I have quite a few big ones but they are all shy of 1". And it wouldn't surprise me that, Blackies, being a bit newer, when glass was more expensive, just never really were produced at 1".

I'm not entirely sure if it's Akro or not. But if it is, it would be a very lazy corkscrew, at best.

Not Akro, maybe JABO.

It looks more Akro to me.

I see a good chance for Peltier. Cherry Bomb?

It would be a big one but I could see it too.

I am thinking JABO for the first one, a very nice Vitro Blackie for the second, and Akro for the third.

Icy cool, Ric!

I was hoping it didn't have some awesome deco design that got obliterated by the sun, because that really would have been been shame.

Mike did have that superpower.

Nice, Art. I'd be interested to know what the sides of the lid look like.

Riker cases are the glass-topped pressed cardboard cases that many folks use to display marbles. I'm sure you've seen them. Mainly because Art just showed one. 😀

I found what Steph said very interesting - maybe the geologists are the ones who need to call it something else. I mean, the mineral is not glass, right?

One Vitro and two MKs is my take on it.

Most likely Pelt but I couldn't rule out Kokomo possibities.

I agree with Alley.

I really like the base glass for the first one, Dave!

Rainbos . . .

Nice examples, Dave. I especially like the blue one!

Nice selection, Gladys!

It doesn't look so unusual now - it seemed much darker buried in the pile. Still a nice one though.

That's a pretty marble, Chris. I think that the word "agate" was initially adopted by American marble companies since it was associated with the quality stone marbles from Germany, which were something they wanted to replicate with glass. As for minerals in marbles, gold lutz and mica were used in early German handmades many years ago. I think aventurine is sometimes purposefully produced and sometimes just results from reactions of certain colorants used in he manufacturing process. I am sure others could add more to this discussion.
