Best Pyrometric Cones for Accurate, Repeatable Kiln Firings
As an Amazon Associate I earn from qualifying purchases.
A digital controller tells you the temperature inside your kiln. A pyrometric cone tells you what actually happened to your clay, because cones measure heatwork, the combination of temperature and time that matures a glaze. Experienced potters run witness cones in every glaze firing, and kiln manufacturers ask for cone evidence before honoring element warranties. This guide covers the cone brands and formats worth buying, when self-supporting cones justify their higher price over standard cones, and which numbers to keep on hand for bisque and glaze work. We also explain reading a bent cone correctly, placing cones across shelves to map hot spots, and building a simple firing log around them.
