Incidental AV?

[marblemanvintagemarbles]

Size is 9/16" on this one. Is it one of thr Mk patches with av?

[Ric]

Yes, MK. It's hard to know whether the AV was entirely incidental or not - I have seen quite a few of them.

I remember showing one that ive had in the past on Facebook and people getting sorta excited about it. Spoke of them like they were intentionally aventurized

I think the AV probably was intentional since all I've seen have AV and I've seen quite a few. But it's hard to know whether that it just bias on my part or not since I likely wouldn't pay any attention to one that didn't have AV - wouldn't be much of a marble without it, IMO.

Unintentional Aventurine is always a thing in any green color from any marble maker from around the entire planet.
It is a common thing to find in any marble that includes the color green—even Akro.
It has to do with the glass recipe in some shape or form or use. 

@Alan more than likely has a better explaination of this and I hope that he chimes in.

Saying that, some Akroware had some intense UV in the green colors that had to be intentional imho.

Some of those two tab ashtrays just light up with it.

Marble—On!!

Yes - MK.  These are more recent.  They usually have excess colorant precipitated out - sometimes chunky.
