Pyrometric Cones are essential tools used as witness cones to monitor ceramic firing in kilns for consistent, repeatable firing temperature. They are made of specifically formulated compositions, including many of the same ingredients as ceramic products. Each cone is designated a number (for example, cone 04), and each cone number measures a fairly small range of firing temperature.
To determine the best maturing temperature for your ware, we recommend that you use three cones for firing: one cone for the desired maturing temperature, one cone right below that temperature, and one cone right above it.
This is Cone 07.
Fifty cones per box. Each one approximately 1" tall.
