Does anyone have a calculation for swapping COBALT CARB for Oxide?  I have plenty of Carb and no oxide and poverty prevents me from buying....

Thank you Brian,  that was what I thought but I really wanted to be certain.

Hi Nadine, I think 1,5 times would be better, and do some tile tests, cause carbonate and oxide won't react the same, as carbonate is more powdery than oxide.

Thanks

Sylvain

Recipe calls for:

10.0 grams Copper Oxide           use 13.9 grams Copper Carbonate

10.0 grams Copper Carbonate     use  7.2 grams Copper Oxide

10.0 grams Cobalt Oxide             use 15.9 grams Cobalt Carbonate

10.0 grams Cobalt Carbonate      use   6.3 grams Cobalt Oxide
