213 Porcelain Clay | Mid-range Porcelain Clay | Cone 6 | American Ceramic Supply Co.

A white body formulated for Cone 6 firing. Plastic and throwable.

Firing Temperature range : Cone 6

(2232–2195°F / 1222–1201°C)

This clay body is formulated for mid-range firing and performs optimally at Cone 6.

For slow firing schedules (typical in gas kilns or controlled oxidation/reduction firings), expect the following temperature benchmarks: For fast firing cycles—often used in electric kilns—the temperatures required to achieve each cone are slightly lower due to reduced heatwork over time:

Note: Electric kilns generally follow fast firing profiles, meaning actual peak temperatures may be up to 30°F (15–20°C) lower than traditional gas kiln firings. Always consider your kiln type and firing schedule when targeting a specific cone to ensure proper vitrification and glaze fit.
