I had been under the impression that Tom replaced a good deal of that sodium with sodium Carbonate and you're giving me information I did not have. I did not know it was that much. Those two formulas would be quite incompatible with the total omission. The point was to get the nitrates out, not the sodium. Antimony can act as both a reducing agent and an oxidizing agent, sometimes dropping to Sb2O and sometimes going up from Sb203 to Sb205

And again, it has to be mixed when you get it. We did make a copper ruby with it the first try when Tom came and took the class way back when in Santa Fe. That even surprised me.
Where are we going and why am I in this basket?
