>3. Spirits of Wine is sulphuric acid
Never! "Spirits of Wine" is alcohol. There is no way to get sulfuric acid
from wine, nor is any introduced during the making of wine. Sulfites, yes,
but not sulfuric. Pray tell me, Terry, where did you get this
misinformation? I'd like to explore the source.
Incidently, I don't have information on any common commercial source for
sulfuric and nitric acids in small quantities. Anyone have this information?
