G-200 Feldspar is a high quality potassium / sodium / calcium aluminum silicate ground to 200 mesh for ceramic applications. Carefully beneficiated and controlled for quality, G-200 offers high potash content and low iron oxide per unit of alumina.

August 2009: The Feldspar Corporation has traditionally blended sodium feldspar from Spruce Pine, NC with potassium feldspar from Monticello, GA. This was done in an effort to match the chemistry from a depleted mine. However this material is being replaced by G-200HP. It is higher in potassium and alkali levels because the blending practice is being stopped by Imerys. They are recommending a 7:3 blend of sodium feldspar (Minspar 200) with the new G-200HP feldspar to match G200. Kona F4 Feldspar has the same chemistry as Minspar but its mine is closing.
