Tiered Geometric Slag Glass Pendant Lamp Shade

This is a spherical, tiered pendant lamp shade constructed in the Tiffany-style tradition using stained or slag glass panels. The shade features an alternating geometric pattern of square and rectangular glass pieces in a maritime color palette, including cobalt blue, emerald green, and light teal or aqua. Individually cut glass segments are joined using the copper foil or leaded glass technique, resulting in thick, silver-toned solder lines throughout the body. The shade is topped with a distinct cylindrical neck or gallery featuring vertical glass panels, finished with a metal ring for suspension. The scalloped bottom edge follows the shape of the lowest tier of glass. In terms of condition, there is visible oxidation (patina) on the metal solder lines, which is typical for its estimated mid-to-late 20th-century age. While no major cracks are immediately apparent in the image, the handcrafted nature is evident in the slight irregularities of the soldering. The glass appears to have a textured or 'seeded' finish, providing a soft diffusion of light. This piece reflects a mid-century modern or transitional style, likely produced by a specialized lighting studio or as a high-quality hobbyist kit piece during the glass revival movement of the 1960s-1970s.
