What affects the value of Miller Slag Glass Table Lamp?

• Condition of the slag glass panels, as cracks or heat-related damage significantly reduce the $750-$900 valuation.
• The integrity of the metal filigree, specifically looking for breaks in the delicate casting or signs of poor restoration.
• Originality of the finish, with authentic aged brass or bronze patinas commanding higher prices than repainted examples.
• Functional status and the presence of original pull-chain sockets or period-appropriate wiring.

How to Identify Miller Slag Glass Table Lamp?

• Look for the 'Miller' or 'Edward Miller & Co' maker's mark typically stamped on the underside of the weighted cast iron base.
• Examine the glass for the characteristic opaque, marble-like swirling patterns created by mixing colors during the manufacturing process.
• Verify the presence of the original cast filigree overlay, which should be securely attached over the caramel glass panels.
• Check for period-correct brass hardware and a heavy cast iron base consistent with 1900-1920 production.

History of Miller Slag Glass Table Lamp

Slag glass lamps, often associated with the Art Nouveau and Arts and Crafts movements, became popular in the late 19th and early 20th centuries. Companies like Miller, Handel, Tiffany, and Bradley & Hubbard were prominent manufacturers. Unlike traditional stained glass, which uses individual pieces of colored glass foiled and soldered together, slag glass is opaque or semi-opaque, created by mixing different colors of glass during the manufacturing process, resulting in swirling patterns and a marble-like appearance. This particular Miller lamp exemplifies the quality and aesthetic of the era, offering a warm and diffused light.
