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.
Pyrometric devices gauge heatwork (the combined effect of both time and temperature) when firing materials inside a kiln. Pyrometric devices do not measure temperature, but can report temperature equivalents. In principle, a pyrometric device relates the amount of heat work on ware to a measurable shrinkage or deformation of a regular shape.
A brand of pyrometric cone. Overfired When an article has been subject to excessive firing, either time or temperature, such that the physical properties have been adversely affected. Overglaze See Enamel, above. Oxidation Oxidising firing A firing in a kiln with an oxygen containing atmosphere.
Around 1782 potter Josiah Wedgwood invented a different type of pyrometer (or rather a pyrometric device) to measure the temperature in his kilns, [5] which first compared the color of clay fired at known temperatures, but was eventually upgraded to measuring the shrinkage of pieces of clay, which depended on kiln temperature (see Wedgwood ...

The roots of the Orton Ceramic Foundation date back to the establishment of the "Standard Pyrometric Cone Company" in 1896 by Edward J. Orton, Jr. In 1894, he was appointed the first Chairman of the Ceramic Engineering Department at Ohio State University, the first ceramic engineering school in the United States.
