RAKU CLAY BODIES

KPS has been in business since 1974 with the same owners. We are essentially a family business and know what it is to make a living by doing pottery. Even if it is just a hobby, it is important not to have your clay and equipment "fight" with you. We have formulated our moist clay bodies through years of experience and customer feed back. Clay should be fun and work with you to be what you finally envision for your creations.

We never substitute ingredients, looking for a cheaper way to make clay. We buy premium ingredients because we know that you will have fewer problems. We take pride in our clay bodies and hope they enhance your creativity. We perform extensive tests, including firing through glaze completion of real pots, to ensure that we are making a consistent and qualilty product before you get it.

KPS Clays are tested and re-tested. We are vigilant about the quality clays we produce.
We employ only mature adults that have worked for us for many years.
Premium materials are used at all times.
Ingredients are screened.
Our clays are carefully dry mixed and water-metered.
We use a penetrometer to test the density of each clay batch.
We do many tests to determine plasticity while the clay is pugging.
Actual pots are thrown, handbuilt or sculpted from each clay.
We use a highly respected ceramic testing firm to produce test bars.
KPS clays are made by potters for potters.
KPS Clays conform to ASTM D-4236 standards and are certified non-toxic.

All KPS Raku Clays contain Kyanite to ease the thermal shock encountered in the normal raku process.

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 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.
