Cone 5 · 6 · 7 – like all of our medium temperature clay bodies, Coffee is designed to fire at cone 6 (1222 °C / 2232 °F). Cone 6 is a hard ceiling: above it the body bloats badly.
Dark brown · the colour develops through cone 5 to 6
Dry 7.3–8.0% · fired 6.5–7.3% at cone 5, 7.0–7.8% at cone 6, 7.5–8.3% at cone 7
Cone 5 2.8–3.2% · cone 6 2.2–2.5% · cone 7 1.0–2.3%
Every figure is a measured range from the Plainsman lab, not a single nominal number. Cone equivalents are Orton self-supporting cones at 108 °F/hr.
Coffee is a dark brown burning stoneware for functional work at cone 6. The colour is in the body itself, derived from burnt umber – a calcined natural clay – rather than applied as a slip or stain, so it runs all the way through the piece.
It is smooth and plastic, throws easily, generates plenty of slip on the wheel, and stays workable even when soft.
Firing to cone 6 is a firm limit rather than a preference. Beyond cone 6, the umber begins to break down and the body bloats badly, so this is not a clay to push to cone 7.
LOI 6–7%
Wheat is a smooth, highly plastic general purpose clay body for cone 6, firing to a warm buff with a light iron speck. It is a lower-cost alternative to our M340 bodies, with a similar maturity and colour at cone 6.

M390 is a smooth, very plastic red stoneware for functional ware at mid range. It carries more native Redstone than any of our other bodies, which is where the depth of colour comes from, and it is a joy to work with on the wheel.
Also available:
M340 is one of our most popular general-purpose clay bodies – plastic, medium-fired and buff burning, and it throws and hand-builds equally well. Best fired to cone 6.
