I find it odd that he would avoid selenium. It's hard to do a lot of color without it. The multi valent atoms are usually your friends.
I would say once again that the morbidity stats on people who melt glass just really show very little effect. The things that are killing off glassworkers are alcohol, tobacco, obesity and Cholesterol. A fair number have had heart attacks or blood clots. I know of one cancer of the kidneys but metal poisoning? I know of two in fifty plus years and they didn't die of it. They both recovered. In both of those cases, the circumstances were egregious.
