50 copper carbonate

Chun glaze is an ancient and traditional Chinese glaze. It is not usually very blue.

Tradtionally blue in a Chun is caused by the reduction of rutile, which can be chancy.

Expect a creamy glaze that spreads into several visual layers. You might get hints of lavender as well as blue.

Cone 9-10 (Frits Hommes variation)

Start with the basic Blue Chun recipe above. To the 10,200 g recipe, add 96 g cobalt carbonate.

Leave out the copper carbonate (but keep the rutile in). This yields a light blue Chun with consistent light blue color, while preserving some of the traditional Chun color variation
