Ice crackle glaze creates a network of interconnected, angular cracks resembling fractured ice. This specialized form of crackle glaze requires precise control of glaze chemistry and firing atmosphere to achieve its characteristic crystalline pattern.

Crackle glaze (开片, kaipian) intentionally creates networks of fine cracks in the glaze layer through controlled cooling. These fractures, often stained with ink or tea over time, form decorative patterns ranging from delicate “golden thread and iron wire” to bold…

Kiln transformation (窑变, yaobian) refers to unpredictable color changes in glazes caused by chemical reactions during firing. This “controlled accident” produces unique patterns ranging from flame-like streaks to iridescent surfaces, valued for their natural spontaneity. Scientific PrinciplesColor variations result from:…
