Co-Efficient of Expansion is a measurement of a material's degree of expansion when heated and contraction when cooled. Altering this value can help achieve a desired glaze fit. Glaze fit is the difference in degree of contraction between a glaze and a clay body. A high value may indicate a tendancy to craze while a low value could indicate a tendancy to shiver.
0 is a low value and could indicate too much compression with the possibility of shivering.

Ratio can indicate the relative gloss or matt finish of a glaze. Ratio is a measure of the proportion of Silica to Alumina in a glaze. Typically a glaze with a high ratio will be glossy, while a low ratio could indicate a matt or semi matt finish. Slow cooling of a glaze can cause crystal formation which will also result in a matt finish, even though the ratio value indicates a gloss finish.
is a low value indicating a less shiny surface.
