What to Look For
How to Identify Antique Lamp Authenticity & Value
Maker's mark
Check the base underside for foundry marks. Tiffany Studios is stamped on the base and often the shade rim. Handel, Pairpoint, and Bradley & Hubbard also marked their pieces.
Glass type
Leaded glass shades with individual pieces indicate quality studios. Reverse-painted shades on milk glass were Handel's specialty. Slag glass was used in less expensive lamps.
Base material
Bronze bases patinated green or brown indicate age. Spelter (zinc alloy) bases are lighter and less valuable. Cast iron bases are common on oil lamps.
Fuel type
Whale oil fittings predate kerosene (pre-1860). Kerosene burners with wick tubes are Victorian. Electric sockets retrofitted into oil lamps reduce value.
Shade condition
Cracks, chips, or replaced pieces in leaded glass significantly reduce value. Original shades must match the base style and period.
