RAKU CLAY BODIES:

KPS RAKU CLAY. Cones 08-10. Designed for extreme Raku thermal shock. Bisques very white, blackens nicely in post-reduction Raku firing. It's a fairly smooth textured, but tuff, plastic body. Makes working in raku easy. This is the closest thing to a universal clay body. It will work well for practically any application-low-fire to high-fire and anything in between, plus you can count on good glaze adhesion and fit all the way up the temperature chart. If you only want one clay, this is the one to use. Glazes very well. Has kyanite for thermal shock. Oxidation, reduction, wood or natural pit firings.

KPS RAKU C. Same properties as above but with the addition of medium coarse grog to give ultra, industrial strength. Good for slab making, large wheel work and handbuilding. Also excellent choice for sculpture and large objects. Bisques white. Will fire to cone 10. Oxidation, reduction, wood or natural pit firings.

KPS RAKU XC. Same properties as above but with the addition of extra medium coarse grog to give crunchy textural feel. Best for slab making, large wheel work and handbuilding. Also excellent choice for sculpture and large objects. Bisques white. Will fire to cone 10. Oxidation, reduction, wood or natural pit firings.

KPS 250 SCHOOLHOUSE RAKU. Cones 08-10. This is our smoothest texture raku clay that really throws itself. It has the heart of a lion and the feel of velvet. It will hang in for the long haul and will not disappoint you. Economy and greatness all in one. This body will vitrify from cone 6-10 and be a light cream color in oxidation and slighty more toasty in reduction. Oxidation, reduction, wood or natural pit firings.

Purge Clay: Purge clay is offered as generic clay suitable for practice or for those not fussy about fired color. Only available locally, not for shipment because these clays are not boxed. Subject to availability, first come, first served. We do not test these clays.Suitable for lowfire use only. NOTE: Purge clays do not carry the ASTM D-4236 certification.

Custom Clay: We will mix your custom clay body to your exact formula using the best materials available. We never substitute an ingredient without your permission, nor do we use cheaper grades of materials. KPS will add sand or grog to any of our existing clays for a small charge. Custom clays must be paid for at time of manufacture. Pick-up must be made within one week. Minimum order of 2000 pounds, please. NOTE: Some custom clays will not carry the ASTM D-4236 certification unless you have paid for LHAMA certification. We can arrange this for you, if needed.
