GAS REDUCTION , WOOD-FIRED and RAKU CLAY BODIES:


Wood Fire Clay

WOOD-FIRED,  RAKU  and GAS REDUCTION CLAYS

We offer specially formulated clay bodies for those of you doing Gas Reduction, Raku work and Wood Firing.

Shown left: Bowl by Nancy Magnusson made with our moist clay 42,
Soda and ash wood fired from her Noribagama kiln. Note that the body of this pot is unglazed... the lizella in this body creates great iridescent blues and purples in reduction kilns!


Avoid the frustrations of wood fired kiln and Raku work with our clay bodies designed to handle the special stress of those processes.

 Our Raku Clay designed with a high percentage of coarse grog to withstand the thermal shock of fast firing and cooling in Raku. Can be used for wheel work, hand-building, and sculpture.

For pit firing, try the Raku clay or S14. These bodies have a wide firing range and good thermal shock absorption.
When pit firing, bisque your pieces in an electric kiln first for better results.
Expect a lot of broken pieces when you pit fire... it's the nature of the beast, but by doing a bisque firing first, you can reduce your loses.
