Oxidation Firing
Perhaps the common kiln that's used in North America is the Electric Kiln. The atmosphere in an electric kiln is generally what we call oxidizing. It means there is no smoke, no atmosphere which is going to change the oxide colours of the glazes that we used. Electric kilns are particularly convenient for very careful colour development and colour control as we see in this small piece of maiolica from Alan Caiger-Smith in England. Very well controlled colour use in here. The electric kiln is particularly suited for very specific colour use.
