Godfrey Feldspar

Description: Soda feldspar

Oxide Analysis Formula
CaO 2.86% 0.36
Na2O 5.54% 0.64
Al2O3 17.07% 1.19
SiO2 74.31% 8.81
LOI 1.50%n/a
Oxide Weight 711.01
Formula Weight 721.84

Notes

Another formula that we have is quite different from the one shown here. There is no way to verify where either one came from, however this one may be more correct since it has K2O, which it is difficult to imagine any feldspar lacking completely.

K2O 0.5
Na2O 0.4
CaO 0.1
Al2O3 1.45
SiO2 6.45
