This handmade porcelain tumbler was lined on the inside with a layer of porcelain clay slip, in which the dendritic patterns formed. This formation is the result of a chemical reaction.
This cup was then glazed with a light blue glossy glaze inside, and an opalescent white/pale blue crystalline glaze on the outside. The cup was then fired in a kiln to 2200 Fahrenheit.
Approximate dimensions: 5 x 3 x 3 inches
It may be used in a microwave and dishwasher.
