Is it possible to add food coloring, or something of the like, to clear glaze, to make its application more apparent?
For years, I used Amaco's transparent clear glaze. It was Pepto Bismol pink. It made applying easy, because you could tell, where you had already covered.
Last year I ordered more of the same glaze, but it's no longer pink. It dries kind of an off-white. It works just as well as the other, but it is hard to tell, where you've applied it, especially if you are going over a white underglaze. I discovered this recently, when I was doing just that. I pulled a piece out of the kiln, and saw a bunch of dull spots, that I missed. Because of that, I missed the mailing deadline, for a gift I was sending, because I had to reapply and refire. Not a huge deal, but I don't want to have the issue again.
So can I add any color of dye to the clear, and be OK. Won't it just burn out, like it does out of my colored wax resist and such?
