How Tiffany glass is colored article by Jim Hoyle

The colors that you see in Tiffany style stained glass shades are an integral part of the glass created by the addition of various metal oxides and minerals to the glass while it is still in the molten state.

It is not accomplished by painting or by use of pigments.

Manganese creates violet colors
Copper creates various red colors and green colors
