I am working with a glaze that has gerstley borate, cause I have plenty. I have only found 2 cone 1 glaze recipes on line.
The recipe I’m working on is clear not quite smooth enough and has tiny bubbles. I want to opacify it for white. I tested tin, zirco, and others. But I’m not getting a good melt. I have some Frits on hand.
Guessing I should fix the glaze without opacifiers first? shall I up the gerstly? Or try frit 3134 or 3124?
