The green man, popular in carvings and adornments especially in England, is sometimes referred to as a symbol of rebirth. This window is the green man, hand painted with kiln fired enamel paint and surrounded by fracture/streamer glass. The glass is lead and solder, which is how most antique windows are made versus the copper foil method.
The frame around the window is made of zinc, stronger than lead and therefore holds the shape without sagging.
Whenever handling lead, always wash your hands afterwards.
Stained glass windows can be hung in front of a window or on a wall with reflective light.
