Bullseye Leaf Green Opal, Emerald Green Transparent Mottle Art Glass
Louis Comfort Tiffany first developed ring mottles in the early 20th century. Artists use them to create the impression of dappled sunlight on petals, leaves, grass, or water in stained glass windows and lampshades.
NOTE: 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.
The mottle patterning, which develops in manufacturing, is heatwork sensitive and changes when fired. At full fuse temperatures, mottles almost completely disappear.
