Leaded Slag Glass Inverted Domes were made by slumping or bending parts of sheets of Slag Glass and shaping them into very interesting designs of different colors and texture. The bending was done by heating the glass in a kiln until it " slumped " to form the shape of the various molds that were used. After the desired shape was created the piece of glass was surrounded by copper or lead foil which then allowed the pieces to be " leaded " together with a soldering iron to form the Inverted Dome.
These Antique Inverted Domes are very often associated with the Arts & Crafts and Art Nouveau period. Their spare but interesting designs work well with the parallel lines in Arts & Crafts furniture. Then some of these Antique Lights had a more organic feel to them.
