I don't know where this is leading with the CuSO4 but I have read
in Michael Tichanes (sp?) book, "Reds, Reds, Copper Reds" that sulfur is an
"enemy" when trying to fire for copper red glazes. Also the sulfur when
combusted can form various forms of corrosive sulfurous gases which could
be of NO benefit to your kiln or the pots within... I would recommend
staying with the copper carbonate. ....Marshall
