An opacifier is a substance added to a material in order to make the ensuing system opaque. An example of a chemical opacifier is tin dioxide (SnO2), which is used to opacify ceramic glazes and milk glass; bone ash is also used. Opacifiers must have a refractive index (RI) substantially different from the system. Conversely, clarity may be achieve...
An additive to a glaze that increases the reflection of light to the observer, commonly tin oxide or zircon.
Material for making transparent glazes opaque or white. Tin and Zircon are two common opacifiers.
A substance, such as fatty acid esters, which, when added to a clear formulation, renders that formulation opaque - similar to pearlizer.
