I found a glaze I want to test, but I'm not sure how to interpret it. Does this mean percentages or weight? How do I go about converting this recipe into grams? G200 0.381 Barium Carbonate 0.19 EPK 0.096 Flint 0.095 Gillespie Borate 0.095 Zinc Oxide 0.094 Copper Carbonate 0.049. I'm been using the same glazes for so long that I haven't had to do this and I'm feeling really math challenged right now.
