You're showing some super examples, Ron - I especially like the latticino in green glass. The horizontal swirl is awesome too, but is it German?

Those are dandy big ones, Ron. Did you by chance get them from another Ron?

That's a nice colorful assortment!

The transparent swirls can be tough, especially the ones that are, essentially, slags. I'd probably stay with Alley. Transparent Ravenswoods are usually a bit more sparse. Regardless, it's nice batch-glass white swirl.

Great marble, Joep!

That's a pretty marble and great photo too!

Hmmm . . . "for your German marbles and related items" - I guess this fits. lol

Oh yeah, those are cool, Bo!

Brian has a great article about this type of 'hand gathered imitation onyx' marble. https://www.briangrahamglass.com/elias-greiner-vetters-son-the-story-of-ground-pontil-marbles/

Naturally colored yellow limestone marble, likely from Sonneberg-Coburg area, early 19th century. Described by Gartley and Carskadden in 'Colonial Period and Early 19th-Century Toy Marbles', p. 105.

It's intriquing . . . If it was a factory box, I would expect to see the company name & address on it, somewhere, either on the top or side of the lid, or at least "made in the USA" along with the logo stamp. It also seems a bit too fancy for a stock box and not quite fancy enough for a gift box so . . . ? Having said this, it's important to realize that I am near clueless about Akro boxes.

Water-driven stone polishing mills are machines, right?😁 a couple of close-ups. And here it is with some non-machine-made stoneware. I'm betting the stone is older. lol

Okay, last one for this week!

A good "R" is hard to find . . .

Thanks for everything, Ron. I like the prospects on that one. Some more of my favorites - black cherry striping on a peanut butter brown base - mmm mmm!

I should have said it's 9/16" too, which is another reason I am hopeful and leaning Ravenswood.

I never actually sampled them, and I stand corrected. The 5% for error seems entirely reasonable too.

These are my most treasured because I got them in trade from a dearly departed Dutch marble friend, Winnie.

Killer marble, is the base translucent/smoky? Really nice!

Brent Marshall You will not see many marbles from this glass artist. The biggest here is about 1 13/16"

You're right, AkroOrka, Alibaba is a great place to scout new marbles, especially of Chinese origin.

Man, I wish this one was mint! Black Brick
