Constructed using the Tiffany style (also called foiled) method. These candle holders are assembled from multiple pieces of stained glass. After cutting and sizing, each piece is wrapped in copper foil. Solder is applied to the copper foil, then the pieces are assembled together. See the steps involved in making these here.
The solder is then finished either as polished, copper plated, or with black patina. The final assembly is waxed.
Examples shown below are just that - examples. No two are exactly alike. You can select the design, glass color and finish (bright, copper or black).
