Hey yall, I am a student and currently have a glaze making assignment for my class and I found a recipe that goes (in grams):
custer feldspar 99
talc 63
silica 48
EPK 45
Whitening 36
zinc oxide 9
+22.5 titanium oxide
6 copper oxide black
6 copper oxide red
I got through making most of the recipe and then found out we dont have the zinc oxide, is there something I could replace it with? I dont care if it ends up not being the color I want as long as it ends up as a high fire glaze. Im very new at this and have no idea what Im doing, please he
