Chiang Mai is the centre of Thailand's ceramics industry. Among it most prized items is the distinctive Celadon pottery, so named for its unique glaze, the result of certain ingredients mixed with wood and ashes applied in a carefully controlled step by step process.
The clay is first treated with additives which are then let in the shade and thrown. After bisque firing at a temperature of 800 C, the glaze is applied. The piece is then placed in the kiln for a second firing at a temperature of 1,250 C, which gives the Celadon its inimitable, finely cracked finish.
