White, Mottle 006013
Bullseye Ring Mottle sheet glasses are non-fusible and not intended for kilnwork. Their formulas are not Bullseye Compatible, and they are not tested for compatibility.
These glasses are designed for "cold" processes such as stained glass and mosaics. Artists use ring mottles to create the impression of dappled sunlight on petals, leaves, grass, or water.
The mottle patterning develops in manufacturing. It is heatwork sensitive and changes when fired. At full fuse temperatures, it will almost completely disappear.
