Lightning Deal 1kg Cobalt Carbonate Cyber Monday Only [vie9n0RM]

CoCO3  A very powerful colorant and flux for glazes (<3%) and slips (<15%) typically producing deep clear blues but also pinks, mauves and greens. It decomposes to cobalt oxide on firing and can be used as a substitute for it in recipes (use 1.5 X more). It is less prone to cause specking than the more concentrated oxide.
