    Typically, metallic salts and oxides are used to color glass. These are added while the glass is in a molten state. “Copper oxides were added to produce green, cobalt for blue, and gold was added to produce red glass. Much modern red glass is produced using ingredients less expensive than gold and giving a brighter red of a more vermilion shade.”
