GILSON & DOPALS OPALS

Attention Glassblowers:
Don't be fooled by the imitation Gilson opal that is currently on the market. It won't work with glass because its made with plastic resin.
These are the real deal, guaranteed.

Synthetic opals by Gilson and Dopals Opals are only compatible with borosilicate glass which is 33 coe.

Shard Sizes are as follows:
(Shard = 1mm to 0.5mm) (Mini = 0.5mm to 0.35mm) (Micro = 0.35mm to 0.25mm) (Nano = 0.25 to 0.10mm)
