Carn - a Celtic word, borrowed into English as "Cairn", means a man made pile of stones. This pottery was started by John Beusmans at Nancledra in Cornwall in the early 1970s. The pottery is still in production.
Beusman's work is distinctive. He carries out the work of thrower, mould-maker and decorator. His pieces vary in shape, size and nature, but are always instantly recognizable. The work is slip-cast and usually several moulds are made from a master, each one incised with a different design. The colour is produced by applying copper oxide and copper mixed with cobalt with a mop. The pots are then fired in an electric kiln at 1140°C.
