Thanks for another addition to the collection. I don't think I need that kind of speed, but out of curiosity, I looked up sources for antimony potassium tartrate and alpha-Thioglycerol, and they seem pretty expensive ($73/125 g of antimony potassium tartrate and about $11/g of alpha-Thioglycerol).

Since I saw it sold by the gram, what is the concentration of alpha-Thioglycerol, and what does it do in the formula?

"Antinomy"?--Kant wrote about them in the First Critique.
