Feldspar

Feldspar is the general term for a range of minerals found in large amounts of the earth’s crust. Quarzwerke process the feldspar and after extensive screening and grinding produce a very pure chemically inert, translucent mineral called nepheline syenite. This contains no free crystalline quartz and exhibits excellent chemical resistance and hardness. The trade name used is MICROSPAR.Read more
