I'll be adding Zicropax, Talc and 80 mesh test and full size sieves to my list.
I do like it when the glaze breaks as GEP mentioned but there will be times when I won't what that to happen so I'll get both zicropax and tin oxide.
I've noticed, and I'm sure everyone already knows, that recipes never include how much water to add or even the specific gravity. I thinking all this depends on how I apply the glaze and its better to start with less and add more water as I go. Right now I'm pouring and brushing and I want to get away from brushing and start spraying or dipping.
So my guess is if I have 100 grams of dry glaze materials I might start with 50mL of water and go from there. Is this sound or is there a better way?
