| Firing | Process of heating a ceramic in a furnace or kiln at a high temperature to make it harder |
| Fuse | To melt together |
| Wedging | Process of cutting |
| Bisque | A ceramic product that has been fired without a glaze |
| Flux | A material used to prevent the formation of oxides or dissolve the oxides as they form. |
| Sinter | To heat for a period of time at a high temperature but below the melting point |
| Glaze | A glass coating that is applied to ceramics |
| Silica | Common name for silicon dioxide (SiO2) |
| Plasticity | Ability to change shape when stress is applied and retain the new shape when stress is removed. |
| Silicate | One of many naturally occurring minerals that have silicon and oxygen atoms bonded together by single bonds. Raw ingredient for most ceramics. |
| Tetrahedron | A shape that atomic particles sometimes form when they combine that is the shape of a pyramid |
| Clay | A fine grained soil consisting primarily of compounds containing SiO2 and Al2O3 |
| Refractory | Type of ceramic with ability to withstand very high temperatures. |
| Abrasives | Ceramics that are used to smooth |
| Metal | Element on left side of the periodic table |
| Nonmetal | Element whose properties are not those of typical metals |
| Glass | Special ceramic that is a noncrystalline solid. |
| Ceramics | Type of substance that is composed of metals or semi-metals strongly bonded to nonmetals. |
| Annealing | a heat treatment used to soften and/or relieve stress in a material |
| Borosilicate | glass with some thermal shock resistance that is used for laboratory glassware |
| Coefficient | # for thermal expansion that represent the % of expansion for each one degree Celsius |
| Fire polish | to heat to a temperature where glass will flow enough to remove sharp edges |
| Former | an element whose oxide will form a glassy network structure |
| intermediate | ingredient in glass that can act either as a glass former or modifier |
| lead alkali | soft glass that is composed of primarily silica |
| Modifier | additive to glass that lowers the melting temperature |
| Plate | type of thick |
| Polarized | type of filter that allows light from one direction. Used to view stress in glass. |
| Score | scratch glass surface so the imperfection can be used in tension to break the glass into the desired shape |
| Soda lime | most common type of glass made of silica |
| Silica | silicon dioxide (SiO2) |
| Tempered | glass type that is cut |
| Sublimation | changes from solid to gas |
| Viscosity | measurement of thickness of a fluid: molasses in January |
| Thermal shock | break when experiencing a rapid change in temperature |
| Source chemical | a chemical used in glass making that will decompose when heated and convert to the desired ingredient |
| Vitreous | glass-like |
