Opacifiers

"Minerals which are included in glaze recipes for their property of opacification. Opacity is the result of light interference inside and at the surface of a glaze. This can occur in three ways: when light strikes opaque matter suspended in the glaze, when light is deflected by crystal facets and when it is deflected by matter of less than wave-length size."
