How did people in the Middle Ages make stained glass?

Stained glass is made by taking pieces of colored glass and setting out to the shape of a picture. The glass is held in place by strips of lead that are soldered together, forming a dark linear element in the picture. The glass could be painted or not. It usually was painted to get such details as eyes, noses and mouths into the picture. It could also be stained to change the color. If it was painted or stained, it was subsequently fired.
