I was looking through my glaze book and stumbled across a chemical I am not
used to seeing. I looked in the dictionary of clay and glaze compounds in
Chappell's "Clay and Glazes" and could not find it or a subtitute. Please
help. I believe I saw a bag at Olympic kiln manufactures labled Ultrox, but
I forgot to ask them while I was there. TIA.
