Summary
Selenium is used both as a decolorizer for flint glass to offset the green caused by iron impurities and as a red colorizr; The problems with adding traditional selenium have to do with high evaporation losses and safe handling of a highly toxic material. As environmental restrictions tighten in North America, other methods need to be considered. Zinc selenite is now used by almost all European glass companies that require selenium.
