Here are some "Frit Marbles". I think that they are Vacor--not sure though.
They glow after you hit them with white light. "Phosphorescence" is the word regarding these.
You can hit them with a lazer light and make little letters/marks on them--pretty cool.
Marble--On!!
Yes, I get it Fire.
These Akro Ox patches are all over the place with coverage, depth and colors involved.
The transaparent part is kinda weird--but I accept it.
I really want it to be a Vitro--just not imho.
Marble--On!!
This is the third time today that I have seen an Akro oxblood patch with yellow and blue involved.
Not real common in my experience—it must be the weather.
This is the hardest to ID of the three but I will stick with it.
Marble—On!!
