Symphony Purple, Blue, White Mottle
Mottle Glass: 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 heat work sensitive and changes when fired.
