Cobalt Carbonate Size:100 g Used for its tan colorA pinkish powder, cobalt carbonate is very fine grained and disperses better than cobalt oxide in the glaze slurry and the glaze melt, and therefor it provides a more evenly distributed color in the glaze. Cobalt carbonate produces vibrant shades of blue in glazes, slips and underglazes and is stable at all firing temperatures. In terms of colorant strength, cobalt carbonate is a weaker form of cobalt oxide though both are good sources of cobalt.
