Whats the difference between a copper foil and leaded piece?
Copper Foil is a method used in building stained glass that evolved from techniques developed by Louis Comfort Tiffany just after the turn of the twentieth century. This method utilizes a copper tape with an adhesive backing that is applied to the edges of the glass pieces. Since hot lead will not adhere to glass itself, the copper foild acts at the medium to form a channel when the hot lead cools. A leaded glass piece is created using lead came, a piece of lead channel that is either shaped like a U or an H and holds the glass pieces together to form a panel.
