Tranlucency


Translucent glazes are neither opaque or transparent. A good example is a matte glaze that contains no opacifier. Glazes that are opacified will of course have varying degrees of translucency according to the amount of opacifier present. A colored glaze can be transparent, translucent or opaque and the color quality with vary accordingly.

Porcelains can be translucent, for example bone china. The translucency is a product of the degree of melting (the more melted the more translucent it will be) and, or course, the wall thickness. Low TiO2 clays are used to make translucent porcelains.

  • (Glossary) Transparent Glazes

    A fully transparent glaze is simply one that does not have opacity. But there are degrees of transparency. For example, if a glaze is matte it will show the color of underlying body and decoration, but these will be muted (so it is actually translucent). Completely transparent glazes look like a gla...

  • (Glossary) Bone China

    True bone china is a special type of translucent porcelain. Instead of feldspar, bone ash is used as the flux. The process requires more careful attention than normal porcelain. The vitrification range is narrow, kilns need to be fired carefully. Ware often warps so badly that it must be fired witho...

  • (Glossary) Opacity

    Ceramic glaze opacity refers to the degree to which a glaze is non-transparent. Non-colored glazes can be either transparent, opaque or somewhere in between. Transparent glazes are glossy (matt glazes, by definition, are never completely transparent but they can be partly translucent to reveal under...
