SCHOOLHOUSE 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.

Custom clays must be paid for at time of manufacture. Pick-up must be made within one week. Minimum order of 2000 pounds, please.
