Ceramic glaze

Ceramic glaze is an impervious layer or coating of a vitreous substance which has been fused to a ceramic body through firing. Glaze can serve to color, decorate or waterproof an item. Glazing renders earthenware vessels suitable for holding liquids, sealing the inherent porosity of unglazed biscuit earthenware. It also gives a tougher surface. Glaze is also used on stoneware and porcelain.

4 Ceramic Glaze Ingredients

 · Fluxes play the key role in lowering the melting point of silica, making it usable in ceramic glazes. And, like silica, fluxes also promote vitrification (the transformation into glass). The most commonly used fluxes in ceramic glazes are obtained from limestone as calcium oxides. Potash feldspar and soda feldspar are good examples.

Feldspars of importance to ceramics are aluminosilicates of sodium, potassium, and calcium (Jones & Berard, 1993) They are used as fluxes to form a glassy phase in bodies, thus promoting vitrification and translucency.They also serve as a source of alkalis and alumina in glazes. The pure spars are albite (NaAlSi 3 O 8), orthoclase or microcline (KAlSi 3 O 8) and anorthite (CaAl 2 Si 2 O 8).

Substituting feldspars is not generally "rocket science". If two feldspars have about equal KNaO (total K 2 O+Na 2 O) then they are likely interchangable. Of course, some feldspars have lower iron content and thus produce whiter glazes. The difference between a soda feldspar and a potash feldspar may not be a much as the names indicate.
