  2. Pyrometric cone - Wikipedia

    en.wikipedia.org/wiki/Pyrometric_cone

    Definition. 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 ...

  3. Pyrometric device - Wikipedia

    en.wikipedia.org/wiki/Pyrometric_device

    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.

  4. Slumping - Wikipedia

    en.wikipedia.org/wiki/Slumping

    Slumping glass is a highly technical operation that is subject to many variations, both controlled and uncontrolled. When an item is being slumped in a kiln, the mold over which it is being formed (which can be made of either ceramic, sand or metal) must be coated with a release agent that will stop the molten glass from sticking to the mold.

  5. Orton Ceramic Foundation - Wikipedia

    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.

  7. Lambert conformal conic projection - Wikipedia

    en.wikipedia.org/wiki/Lambert_conformal_conic...

    Aeronautical chart on Lambert conformal conic projection with standard parallels at 33°N and 45°N. A Lambert conformal conic projection (LCC) is a conic map projection used for aeronautical charts, portions of the State Plane Coordinate System, and many national and regional mapping systems. It is one of seven projections introduced by Johann ...

  8. Orton Memorial Laboratory - Wikipedia

    en.wikipedia.org/wiki/Orton_Memorial_Laboratory

    Built in 1929, Orton Memorial Laboratory was originally used as the headquarters for the Standard Pyrometric Cone Company. The company was established by the son of the founding president of the Ohio State University. The laboratory was designed by Howard Dwight Smith, the same architect who designed the Thompson Library and the Ohio Stadium.

  9. Cone - Wikipedia

    en.wikipedia.org/wiki/Cone

    3D model of a cone. A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex. A cone is formed by a set of line segments, half-lines, or lines connecting a common point, the apex, to all of the points on a base that is in a plane that ...
