Really?  I was thinking that but whats the difference between a game marble and something like a solid CAC or the like?  If it’s too long to answer no worries, I’ll do more studying haha…

Don't think of a glass pot as a perfect, singular and constant source.  Marble making was/is an incredibly cheap, mass production process.  Variations always occur.

The Persian blue could be made by vitro. Mine react to uv .

I personally like the early game marbles they have some character and usually the colors were muddy if that's the correct term.

The CAC question is tough to answer so I'll leave it with you research.

I've been told if it's a CAC you'll know .

Happy hunting.

I appreciate any and all help.  Thanks again.
