Potters & Sculptors - Making Rock from Mud
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.
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
