Oh lord, the old red/ orange problem again.

Here are the following ways they can be produced:
Cadmium, Lead+chrome, uranium, copper (under the right conditions.)

The first three will mess you up good! The latter is difficult and tempermental. For earthenware (eg. much, but not all, cast barware) there exist some pretty reliable commercial cadmium glazes which won't kill you. At porcelain (diinerware, whiteware, stoneware) temperatures, you can forget it. At least for the red. You can get purpleish red, or orangeish red without doing the copper thing I mentioned. However, a certain company has just developed a new fire-engine-red high temp glaze which is supposed to be non-toxic. I'd be interested to try it out, but it's not yet on the market.

I have been working on a glow-in-the-dark glaze, and have faith that it will soon be working well. Any thoughts on that? You could find your drink if the lights went out...
