Fused Glass Frit

A fused glass frit plate made from one piece of fusing glass and different colored frit fused and slumped in a glass fusing kiln.

The fused frit plate has one piece of red fusing glass with a coating of coarse and medium frit.

The colored frit gives the plate a floral appearance.

Colors and size can be altered to suit mold size.

This type of design will produce some brilliantly colored glass art.

Bullseye materials have been used for this design.
