That feldspar, however, was considerably higher in its potassium content. They resolved the chemistry by trucking a soda feldspar in from Spruce Pine, NC (about 250 miles distant, probably from a mine near the Minspar source and the now-closed Kona F4 source mines) and blending it 70:30 Siloam potash spar:Spruce Pine soda spar.

Feldspar Chemical Composition
The specific chemical formula is KAlSi3O8 – NaAlSi3O8 – CaAl2Si2O8. The minerals are chemically alert and have a stable pH value. In the Physical properties of Feldspar, we can say that the Feldspars have a monoclinic or a triclinic crystal system and the refractive index of this mineral is 1.518 – 1.526.

The Mineralography of the Feldspars Part II
As our knowledge of the feldspar group, outside of crystallog-raphy, is to a very large degree confined to the plagioclase series, about one-half of the present paper is devoted to the potash-soda series.
