Feldspar is used in various industries, but it is mainly used in thermal industries such as in the making of pottery, porcelain, faience, glass and metal painting through functioning enamel. A little amount of it, not more than 10 %, is used for other purposes like the filling materials, painting and for the making of some sorts of soap.
Feldspar is taking its economic value when found separately or when found separable. For this reason, it is accessible to extract it from the veins that contain it in the rocky base.
