Beading is the crucial finishing step in the copper foil technique, a method Tiffany Studios used to construct complex, three-dimensional lampshades. After the lampshade was removed from the mold and the entire interior had been fully soldered for maximum robustness, beading was applied to build up the solder lines on the exterior.
Purpose and Process of the Solder Bead
The purpose of beading was twofold: to soften the sharp edges of the copper foil and to refine the metalwork to create a rigid, self-supporting shell. The process creates a semi-circular profile that contributes to both structural reinforcement and visual refinement. Achieving these consistent, perfectly formed solder beads required an exceptionally high level of skill and years of practice from the artisan. Once completed, the silver-colored solder of the bead was patinated (chemically discolored) to a dark tone, such as bronze or copper, to ensure aesthetic harmony with the Favrile glass and the bronze base.
Role within the Copper Foil Method
The copper foil method allowed Tiffany to create the complex, organic Art Nouveau forms that were impossible with traditional lead came. Beading was the perfect technical complement to this method, giving the fragile glass construction the durability required for a product of this quality.
