Raku Some pieces are fired plain while others have a coat of slip and then glaze applied before being fired.
The kiln is heated rapidly. When the correct temperature is reached the work is removed from the kiln and immersed in sawdust. This stage is definitely the most exciting and dramatic! The resulting carbon is absorbed by the clay body imbuing it with its own special qualities. The glazed pieces are allowed to cool before being covered in sawdust. As the glaze cools rapidly it crazes. When placed in the sawdust the carbon seeps into the resulting cracks in the glaze. It is absorbed by the slip and then the body to produced the characteristic effect. When cooled the glaze and slip are easily removed – it’s a bit like peeling a hard boiled egg!
