Ash glaze

Description

A ceramic glaze that contains a high proportion of plant ash. Ash was used as a glaze component since the Han dynasty in China. Because a wide variety of waste products (wood, leaves, seed pods, sawdust, bark, etc.) are used to produce ash, it has a wide range of compositions (silica, potash, lime, carbon, etc.). This variability in composition gives unreliable and often unsatisfactory, results.
