What is Raku?

Raku Body

When making pieces for raku firing, consider the stress the process puts on the work. The thermal shock will crack large pieces made from most fine textured clays, so it's best to use a body containing sand or grog. Long Beach is good for medium sized pieces, and B-mix with sand will work if you need a white clay to use with crackle. Large pieces should be made of a coarse raku or sculpture body. Any piece that's at risk of cracking or exploding in a stoneware firing is doubly at risk when raku fired, so be sure to construct raku pieces well. While the clay is still in the bag, consider how to design the piece so it can be sensibly removed from the kiln with tongs. Avoid extremely fragile pieces or very heavy thrown pieces.
