Thanks for sharing that glaze. I've used a ^6 "tomato red" glaze that I got off the ClayArt web, but it only goes really red when it fires at certain angles, otherwise it has a greenish, brownish color that is not bad, just not red.

does this "really " require 325 mesh silicia? i hope so becuz my 200 mesh silica produced a chocolate glaze. not the georgeous Mcg red I have used from a bucket at JCC. John is right it is a beauty when done right.

I would also ask either Frank (our assistant) or Mike Lalone ans see what they say. Let me forward your email to him but get back to me on the answer if he doesn't "reply all".
