Da Roberto

Or it could be Heaton, similar to these below, but weaker...

Yes, very beautiful!

I don't think there was any dull yellow in this performance I knew there are reds with a transparent base (rarer)

Not the three yellow ones though.... the first ones at the top are of first execution

Peltier "Boyce lundstrom" second performance 2001

Nice piece! I am always attracted to these things

Certainly,... to be taken into account

Take a look here... https://www.greatchicagofire.org/item/ichi-64557/ https://www.allaboutmarbles.com/viewtopic.php?f=5&t=48372&p=350491&hilit=Mystery+of+art#p350491

Very close, but not ox for me....

Hello I accidentally saw with much delay this thread Well, it is a marble "BERRETTI" (Laura Berretti) currently produced in Italy (Firenze)..... even if fire is already aware of it They are cold and heavy because they are made of ceramic They have also been shipped to the United States I have some, see link...https://www.allaboutmarbles.com/viewtopic.php?f=5&t=49805&p=359418&hilit=berretti#p359418

Alley

Vacor "orca"

Maybe Vacor "neptune"

It would take more views but I think it is a Vacor "orca"

I think he is a bit familiar with mine, I can't say exactly if Alley or Ravenswood, but I think more of Raven.... at least, on my Brown swirl

Akro

Possible single seam cac

Perhaps one of the most recent ones , rather lackluster ones to keep up with the Japanese and Chinese competition, or some washing

Akro maybe

No

Alley for me

Oops, yes true, I confusion up a bit with Peltier second run

👍

Alley Sistersville

Yes these ashtrays should be Vitro Oh, if you move the Geiger counter, it should be unsettling.....
