Code 3103 Copper Carbonate.
CuCO3. A finely divided compound similar in properties to Copper Oxide, often used to prevent specking. 1-4% addition. Will give an apple green colour under neutral or oxidising conditions, except in alkaline glazes when a turquoise blue is obtained. Whilst in reducing conditions a copper red colour is produced sometimes known as sang-de-boeuf. The carbonate form gives an evenly textured green glaze due to its fine particle size (3 – 7%)
NOTE – when added to low solubility glaze, copper causes the solubility of the lead to be greatly increased, making the glaze unsuitable for use on vessels containing food stuff or beverage.
