The Chemistry, Physics and Manufacturing of Glaze Frits
Silica sand: It slowly dissolves in the melt when its viscosity decreases enough to enhance migration speed of silicon ions through the glassy network. Usually we have a good speed when temperature is 200–300C above the melting temperature of the frit (viscosity is .

glass | Definition, Composition, Facts |
Fused silica itself is an excellent glass, but, as the melting point of sand (crystalline silica) is above 1,700 °C (3,092 °F) and as it is very expensive to attain such high temperatures, its uses are restricted to those in which its superior properties—chemical inertness and the ability to withstand sudden changes of temperature—are so ...

Glass dust, however, is not crystalline silica dioxide but amorphous silica dioxide. As with many situations, the devil is in the details. Here's a closer look. A crystal is a solid material that occurs naturally during cooling from its melting point where its molecules align in a very regular and organized manner.

` Refractoriness is essential while casting high melting point materials. ` The refractoriness of the silica sand is highest. Fineness ² ` Finer sand molds resists metal penetration and produces smooth casting surface. ` Fineness and permeability are in conflict with each other and hence they must be balanced for optimum results. Bench Life ²
