The pyrometric cone is "A pyramid with a triangular base and of a defined shape and size; the "cone" is shaped from a carefully proportioned and uniformly mixed batch of ceramic materials so that when it is heated under stated conditions, it will bend due to softening, the tip of the cone becoming level with the base at a definitive temperature.
-- "The term pottery includes many varieties of ware from the crudest vessels of prehistoric times to the most beautiful decorated porcelains, stoneware and earthenware; it also includes many articles such as large grain-jars used in ancient times for storing corn and other dry materials, wine-jars and modern sanitaryware and the large tanks ...
Rather than shrink as rings do, a cone's tip will bend forward to the same level as the base at the time of maturity. Other deformations of a cone, such as bloating, cracking or bending backward, can be appropriately interpreted to troubleshoot activity inside the kiln. Discs Are calibrated ceramic disc-shaped devices.
One of Seger's most impactful works was his 1886 essay Standard Cones for the Measurement of Temperatures in the Kilns of the Ceramic Industries, which was the first to specify formulas for pyrometric cones. These cones enabled ceramicists to precisely identify the actual heat-work experienced by ceramics through monitoring the cones' slumping ...
In production, first, a large clay cone was shaped on the disc. The peak of the cone was the actual point of rotation, around which the bowl was to be formed. It was then sliced off with a wire or a cord. The resulting bowls had a relatively thick wall near the base and marks from rotation and pulling on the underside of the base.
