With St. Patty's Day coming up, I thought I would spread a little "luck of the Irish" . . .
The biggest is 15/16" and the Rainbow Red is just for size comparison.
If those are made from Alley cullet I will be astounded - the likelihood seems near zero to me.
Here is a pic from the JABO Jalley run that @Bocci posted at Jabo Collectors of America
At this point, it seems the likelihood they are JABO is higher than the likelihood that they are Vitro but I am still interested to know what Josh @Nantucketdink thinks about them.
I really don't see anything that would make me think they are made by different companies and I think the likelihood that they are is very small so I am not sure what to think now.
Transparent red base glass is very uncommon for Vitro and it's quite common for JABO so . . .?
They all look the same to me. And I sure thought the dark color on the mibs in the OP was purple and not red covered by blue or something. Can you show me a pic of all 5 together but grouped by base glass?
