The natural properties of Feldspar are: - Crystal shape: Single or triangular - Color: Orange or Orange Orange - Scratch: White, yellow or pink - Hardness: 6 - Specific density: 2,54 - 2,76 Feldspar is used in many industries, mainly the manufacture of glass, ceramics and abrasives, as well as used as fillers in the manufacture of plastic, paints and rubber and recently began to use feldspar in the manufacture of electrical insulators and plastic domes. Technical specifications: We have different types of feldspar, whether or not, or veins, where we have the raw materials third grade total potassium oxide and sodium oxide to 14%, and our mines are characterized by the quality of raw material and contain a large reserve
