Copper Foil

| The mil-thickness copper material, often adhesive backed, used to join separate pieces of glass. The technique of joining pieces of glass where foil is centered on the edge of each glass
piece, then bent over the edge to cover a very small portion of the back and front faces of the glass. Pieces are abutted and solder is melted over the exposed foil surfaces, causing the foil-covered glass edges to become joined. |
