The technique popularized at the beginning of the 20th century by Louis Comfort Tiffany – creator of Tiffany Lamps (and many other things). The invention of the copper foil technique allowed glass artists to use smaller and more intricately shaped pieces to make stained glass works of art. Glass is cut into the required shapes, ground down to dull the edges then each piece is wrapped with thin copper foil. The pieces are laid beside each other and the whole piece is then soldered with tin/lead solder along the thin strips of copper.
