Raku is a Japanese technique of glaze firing closely linked to the Tea Ceremony. It involves removing the glazed pot from the kiln when the glaze is molten (around 900 degrees centigrade). The glazed pot is then put into a reduction chamber (usually an oil drum or galvanised bucket) and covered with sawdust.

Copper fuming is achieved by the application of a 90% copper oxide and 10% glaze mixture onto the surface of the pot, which is then fired in the normal Raku way. This gives beautiful vibrant colours and a velvet textured finish. It is notoriously difficult to control.
