Ash glazes

Definition

Ash glazes are a type of ceramic glaze created by mixing ash from plants, trees, or other organic materials with clay and water to form a liquid coating that is applied to pottery before firing. These glazes were significant in ancient Chinese ceramics, particularly during the Han dynasty, as they provided both functional and aesthetic qualities to the pottery, resulting in unique surface textures and colors after firing.
