This clay is the same formula as Soldate-30, but contains finer 60 mesh sand. The texture is medium coarse. Gray in the raw form with a high sand content which makes it an ideal choice for large thrown pieces and sculptural forms.

An outstanding, all-purpose, orange/brown, moist body. Has fine sand and is a difficult body to crack during firing. Durable and affordable. Good for professional or student. Reduces a warm orange/brown, lighter in oxidation.

Gray in the raw form with a medium sand texture. A popular body for general purpose use. Large and thick-walled pieces are prone to cracking. In light to medium reduction, Rod's Bod fires to a warm brown with iron specks which generally bleed into glazes forming brown specks.

As of October 2022, Buff Plus now uses only 40mesh fireclay and 35 mesh grog.
A medium-range light stoneware body with about 9% fine grog which fires off-white to buff in oxidation and slightly darker in reduction.
Flint Hills clays have been evaluated by a nationally certified toxicologist, and have been found to be in compliance with ASTM C-1023 and D-4236, and to not contain any material in sufficient quantity to be toxic or to constitute a chronic health hazard when used responsibly.

A non-iron based high-fire stoneware body with about 18% grog (30 mesh flint grog). Fires to a buff color and provides a good background for glazes. Suitable for high-fire throwing, sculpture, and handbuilding as well as raku and primitive firing methods.

RECOMMENDED VIDEO: Stoneware White with Grog by Bracker's
A low fire red clay with about 18% grog (30 mesh flint grog) that fires to a light red-orange color at cone 06 to 05, and a richer, deeper red color when fired hotter, up to about a cone 2.

Has the plastic nature and glaze friendly creamy color of B-Mix with Grog and all the added qualities of paper clay. It is a great choice for sculptural vessels and has the positive throwing qualities you expect from B-Mix with Grog. Can be fired in a wide range of temperatures from cone 04 to Cone 10.

For years Kansas Clays (and Flint Hills before them) has been making this special blend of Domestic Porcelain for production potter, Steve Coburn. The addition of both 30 and 120 mesh Molochite gives this clay additional strength without compromising whiteness, while the addition of 100 mesh kyanite reduces shrinkage.
Fires gray-stony-white in reduction at cone 10, off white at cone 5 oxidation, and bright white at cone 05 (raku). It is a medium textured, low shrinkage body designed for large-scale hand-built sculpture and tile work where thick cross sections (up to 1 inch) are anticipated. Contains a moderate amount of fine and medium mesh grog.

A medium coarse clay body which exhibits excellent throwing characteristics. This material pulls up well for tall vertical forms without downward creep. Also throws well horizontally holding near flat cantilever flanges on bowls without slumping. The clay both stretches well on big bellied pots and necks as well as on pinch neck bottles. It should be noted that the fine wood fiber content of this clay makes it necessary to reduce the amount of water added to the clay during throwing. Excessive use of water will negate the forming advantages that the fiber produces in this clay. Bob's is also an excellent sculptural body with remarkable resistance to cracks and warps. It is highly grogged with a toasty color. Fires from cone 04 to cone 6.
