Shirley Cadmus: RAKU FIRING!
A word about clay
The type of clay used for each type of firing is important!
RAKU: Clay meant for Raku firing should contain a good amount of sand or grog. This should prevent the piece from shattering during the rapid temperature change during the firing process. My favorite was Soldate 60. This is a good strong plastic clay that can also be fired to cone 10
PIT-FIRE: I like to use a white clay for this type of firing to achieve a contrast from white to black, to Smokey gray.a low to mid~range firing temp should work well. If a smooth texture is desired, burnish before firing
WOOD-FIRED:Any stoneware clay that appeals to you-I usually usually used Soldate 60 for this also but many stoneware clays and porcelains are available
