Clarity, Colour & Economy
This glass is suitable for both glass fusing (C.O.E. 90) and stained glass. Really easy to cut this one.
Wissmach 90 C.O.E is made for glass fusing and kiln forming. Special care has been taken to avoid devitrification and all our Wissmach fusible glass is compatible with all other 90 C.O.E products.
