Does anyone have the molecular formula and weight of the soda spar Minspar?
I've searched all my notes and it's nowhere to be found, nor is in in my
Insight program. :-(
Much appreciated!
Thanks!

June,
Here is the analysis I got from the company that mines it. For
those who may not know, Minspar can be subbed for F4 spar in
glaze recipes.
Minspar 200 (NOT the same thing as Minsilspar)
SiO2 68.6%
Al203 18.5%
Fe2O3 0.06%
CaO 1.5%
MgO Trace
K2O 4.1%
Na2O 6.9%
L.O.I. 0.3%
