Feldspar Lumps, Application : Ceramic,Glass Manufacturing,Glazes

We are offering feldspar lumps. Feldspar is the name of a group of rock-forming minerals which make up as much as 60% of the earth's crust. Feldspar crystallize from magma in both intrusive and extrusive igneous rocks, and they can also occur as compact minerals, as veins, and are also present in many types of metamorphic rock. Feldspars are also found in many types of sedimentary rock. Feldspar powder is of two types (potash & soda). It is based on na20 & k2o % for deciding its use in various applications. Other major content is silica. It is widely used in many industries like ceramics & welding rod.
