Melting Points of Rocks and Minerals

Melting Points of Rocks Igneous rocks form through the crystallization of magma.There is a considerable range of melting temperatures for different compositions of magma. All the silicates are molten at about 1200°C (when a part of rock) and all are solid when cooled to about 600°C. Often the silicates are grouped as high, medium and low-melting point solids.

But feldspar is both easily obtained and useful. It is an ingredient employed in both glassmaking and ceramics. In glass, the aluminium oxide content of the mineral helps toughen the product both for containers and glass fibres, while in ceramics, alkali metal oxides lower the melting point of the mix, achieving a unified material.

Potash Feldspar Digitalfire

Notes. One of the most important materials for medium and high temperature ceramic glazes. Potash feldspars are often not as pure and white as soda spars. A feldspar is typically referred to as 'potash' if there is significantly more potassium than sodium (typically there will be 2-5% Na 2 O).If the amounts are closer to equal they are termed potash-soda feldspars (or vice versa).

Spodumene Digitalfire

Spodumene can also be substituted for part of the feldspar complement in a recipe without disturbing overall chemistry too much (other than substituting Li 2 O for KNaO). Some types of spodumene do contribute to the formation of bubbles in the glaze slurry.

Melting of Amphibole-bearing Wehrlites: an Experimental

Wehrlite melting produces higher CaO content than lherzolite melting, but only at high MgO concentrations (i.e. high temperatures and high melt fractions). Nepheline-normative ultra-calcic melts from arc settings (Della-Pasqua & Varne, 1997; Schiano et al., 2000; de Hoog et al., 2001) cannot be explained by melting of lherzolites or wehrlites.
