Quartz is an unusual mineral. It is stable below 573 degrees Centigrade, but between 573 and 870 degrees, tridymite, (another silica mineral,) forms. At 1470 degrees, tridymite undergoes a structural rearrangement and becomes cristobalite, which is isometric. At 1710 degrees, cristobalite melts to a viscous liquid.

Quartz is a naturally occurring silicate mineral composed of silicon dioxide (SiO 2 ). It is one of the most common and available minerals on the earth's surface. It ranks 7.0 on MOH (Measurement of Hardness) scale, behind topaz (8.0), sapphire (9.0) and diamond (10.0). While quartz is abundant throughout the world not all quartz are suited ...

Agriculture dolomite. Dolomitic limestone, often referred to as 'do-lime', is a mixture of both calcium and magnesium carbonates. Do-lime should be used on soils with a magnesium soil test of 100 ppm or less. It is an excellent and inexpensive source of magnesium for acidic soils. On soils with a magnesium test greater than 100 ppm ag-lime ...
