I think there is new hope. I have been messaging hundreds of people for days saying this is not about bashing Plainsman, it is about keeping Digitalfire free. Please cool it and wait.

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
