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.
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.
Orton developed a series of pyrometric cones and established the Standard Pyrometric Cone Company to manufacture the cones, which continue to be used. He died in 1932, and in accordance with his will the Edward Orton Jr. Ceramic Foundation was formed as a charitable trust to operate of the Standard Pyrometric Cone Company. [8]
Pyrometric cones Hermann Seger (1832–1893) was a German ceramicist who is widely credited with pioneering the development of the pyrometric cone , which enabled the rapid growth of the ceramic industry around the turn of the century.
The show's title was taken from the constraint on submissions, which must fit within the box in which Orton's pyrometric cones are shipped, 3" x 3" x 6" (approx. 75 mm x 75 mm x 150 mm.) Submissions were adjudicated by up to four members of the ceramics art community in the United States, and exhibited during following year's the conference of ...
The Orton Memorial Laboratory is a historic building in the Weinland Park neighborhood of Columbus, Ohio. It was listed on the National Register of Historic Places in 1983. [1] [2] Built in 1929, Orton Memorial Laboratory was originally used as the headquarters for the Standard Pyrometric Cone Company.
ASTM standard C24-01 does relate to the use cones but, and to quote, “ ... the determination of the Pyrometric Cone Equivalent (PCE) of fire clay, fireclay brick, high alumina brick, and silica fire clay refractory mortar by comparison of test cones with standard pyrometric cones under the conditions prescribed in this test method.”
