akroorka

"Melon Balls" are one color in my experience at least. There should be some sort of "Pontil" included. This one appears to be machine made and if I had to guess on the maker it would be Master. Marble--On!!

That cat is just a killer cat-love him/her. Marble On!!

I love them as well--you keep collecting what you like--we all do--collect what we like. I have Sauerkraut in my veins. Marble—On!!

I would call this one an Akro slag--nice one! Marble--On!!

Lets call in @Nantucketdink for an opinion here. He knows these like no other.. Marble--On!!

Vitro X2-- Marble--On!!

MK an Vitro were the most known for this. Marble--On!!

There is no AV here that I can see. These used to be called Akro "Experimentals"--this one is a dug Akro imho. The cutlines line up with what I think. I appreciate all opinions and hope to see some more. Marble--On!!

I would sort this one as a weird Vitro. Nice marble though--Thanks for sharing it. Marble--On!!

This one is nailed--welcome COVRSWAP to "TheMarbleConnection". Show us what you have-- Marble--On!!

I have seen this color/pattern before--in an Akro Cork--I wonder? Prizename? Marble--On!!

I think that @Steph would agree here. Marble--On!!

This is a classic example of a veneered marble. Notice the white that shows in the cutlines. If you were to break this one open it would be all white inside. I think that @Melissa has some input to share here. Marble—On!!

Vitro Oxblood is a bit weird--if it were mine--I would call it ox for sure. Of course, I appreciate all opinions and hope to see some more. Marble--On!!

Pretty funny Ric. I agree with Jabo--lol. Marble--On!!

Al and Ric are right one with this one. It is a nice find and a great ask--a keeper--these are quite old and getting harder and harder to find. Marble--On!!

"Just Corks" are you kidding--these are Akro Corkscrews---the best marble ever made. Marble--On!!

There are slags and there are SLAGS!!! Very Nice!! This is number two on my list--Number one is an "Electric Yellow" CAC. Marble--On!!

Alox sounds right that was my first thought-- Marble-On!!

The white--at least some of it here, is opalescent. I have an eye for this stuff—just sayin. Great marble! Marble—On!!

The clearity of the glass makes me push towards a USA made classic of some sort. It has big bubbles though and one not quite finished cutmark--kinda ruff really. If the second image on the left if a cut-line along with the third image on the left--a slight "V"--Vitro--no name. Nice find--no better ID from me at least. @Ric is right on again. Marble--On!!

X2-- a weird dug Vitro. Marble--On!!

Just my opinion here, It is not an Akro, not a CAC, not a Jabo---- Marble--On!!

This is no regular Rainbo but it is a Pelt imho. I appreciate all opinions and hope to see some more--. @Chad G.? Marble--On!!

I collect corals--this one would be included--just barely though. Nice marble!!
