G200 is a potash feldspar that can be substituted for Custer feldspar in
many mixes and is generally cleaner.
It offers high potash content and low iron oxide per unit of alumina. G200
may produce a more transparent glass than custer feldspar.

A high quality ceramic feldspar ground to 200 mesh for ceramic
applications. It offers high potash content and low iron oxide per
unit of
alumina. Thus, some practitioners claim that G200 produces a more
transparent glass than custer feldspar.
