LEADED
This style of stained glass window has remained largely unchanged for centuries. Each piece of glass is scored and then broken in the proper shape. The window itself is built one piece of glass at a time, with each glass piece surrounded by a framework of lead that is then soldered together.
FACETED
Also called Dalle De Verre, faceted glass windows use slabs of colored glass called dalles, which are cut into shapes using a diamond bladed saw and held together with a two part epoxy matrix.
