Feldspar is a naturally occurring rock-forming substance that is found in large deposits throughout the earth’s crust. Feldspar is what gives granite its grey color and has been used as a home remedy to counter various health conditions for centuries. If not produced and processed correctly, feldspar can display carcinogenic properties. In low doses, feldspar has been associated with reducing inflammation of the joints and has shown promise as an anti-diabetic agent. Feldspar is found in different rocks like granite, basalt, diorite, gabbro, etc. These rocks are basically glassy and also called as fused sediments. Feldspars are calcium rich alkaline minerals which are silicates of aluminums and alkaline earths. Some of these minerals degrade to alumina bi-silicate or micro-crystalline quartz.
