This glaze is great when you just need a change from what you’ve been doing. The bowl at right was done with the base glaze, reduced. No colorants were added, so I was quite surprised when this purple came out. It seems to come out very regularly when un-tinted titanium is used.
Adding colorants seems to destroy this purple. When I added rutile to the Granite base, I got a brilliant orange. Reducing this orange color gave me a slightly less-pinkish, more “burnt orange” color, that I quite like. There is no tinge of purple at all, which I suppose is just as well.
I have had success firing this glaze as low as cone 7, but the size of the zinc silicate crystals you can grow in the glaze seems to be directly related to the temperature at which this glaze is fired: the higher the cone, the larger the crystals. I suspect this is true of crystal glazes in general, but I’m only quite sure of it in this one.
