These strong colouring oxides and compounds 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.
