It is a variation of the traditional technique of stained glass. This process was applied with great skill by Louis Comfort Tiffany at the end of 1800, to create lampshades, decorative items and the very well known windows. It was originally created by cutting strips of copper sheets, with which they surrounded the individual pieces of glass. The copper border was held in place by a small welding. All the pieces of glass so surrounded were pushed together and tin to form the complete panel.
Tiffany technique is expressed with very fine lines that allow you to work with curved surfaces. Even some large pieces of Pandora Murano glass jewelry, as long pendants or earrings are made with the Tiffany technique. For the construction of a lampshade, to the equipment needed for lead glass, you add the copper adhesive tape, handy replacement of strips obtained from copper sheet.
Any form of object, spherical or conical or bell-shaped, is made with a silhouette of wood, metal or cardboard, on which it is designed and assembled the piece. Upholster the silhouette with a layer of paper and draw the ornamental pattern. Remember that the more the curve is emphasized, the design should be more fragmented. You cover the design with shiny paper and review the lines with a soft pencil. Trace it on cardboard and cut out the shapes. Cut the templates of cardboard with a scissor or a double knife, equal to the thickness of the copper tape and the weld, which varies from 0.8 to 1 millimeter. Cut the glass, following the directions of the sketch.
Often the pieces are as small as in necklaces of Pandora Murano and therefore require an accurate grinding. The work must be very precise. Run the edge into sticking the copper tape on the corner of each piece of glass, then going over the lapels with the crushing-copper tool. Assemble the pieces directly on the matrix, welding them on only a few points.
The lamp is made by combining together the dowels. Weld the joints with tin on both sides. To polish the weld pass on the surface an antiquing coating and beeswax. The Tiffany technique was born and developed in the United States where it completed a revolution with the introduction of opalescent glass.
