SELENIUM DIOXIDE
Selenium dioxide imparts a red colour to glass. It is used in small quantities to counteract the colour due to iron impurities and so to create (apparently) colourless glass. In larger quantities, it gives a deep ruby red colour. Selenium dioxide is the active ingredient in some cold-bluing solutions.

Many people wonder when is the right time to take selenium. Taking it is independent of the time of day. However, selenium in the form of dietary supplements should always be taken with a meal if you have problems taking capsules and tablets on an empty stomach.
