Ummm, the left hand one could be a Master Glass "Catseye"--they can be quite funky looking--this would be a nice one.
The right hand one may be Akro or Master with a lean toward Master.
Marble--On!!
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!!
