Corning Ware, Pyroceramics, Pyrex

While this is a trade-name of a specific type of ceramic available, the term is also used in a generic sense to refer to porcelain tableware that has an extremely low thermal expansion. While a trade secret of the Corning company, it is well known that oven-to-table ware is produced by controlling the firing curve to achieve the development of the beta spodumene phase in the porcelain microstructure. 'Pyrex' ware is a low expansion high silica borosilicate glass.

  • (Glossary) Co-efficient of Thermal Expansion

    A measure of the reversible volume or length change of a ceramic material with temperature. The more the expansion during heating the more contraction must occur while cooling it back down. Expansion values are very small and recorded in scientific notation (e.g. 6.5 x 10-7 which is 0.00000065). Typ...
