RAKU is an ancient Japanese method of firing pottery. Raku ware is a type of Japanese pottery traditionally used in Japanese tea ceremonies, most often in the form of chawan tea bowls. It is traditionally characterized by being hand-shaped rather than thrown; fairly porous vessels, which result from low firing temperatures; lead glazes; and the removal of pieces from the kiln while still glowing hot. In the traditional Japanese process, the fired raku piece is removed from the hot kiln and is allowed to cool in the open air.
We use the Westernized version of Raku where the pot is pulled from the kiln when hot and then placed into a trash can of combustible materials to smoke the pot.
