Substantial early 20th-century slag glass table lamp featuring a heavy spelter (lead alloy) cast base and paneled shade. The shade and base panels use genuine slag glass with warm amber/caramel tones that illuminate beautifully. The cast metal body shows age-appropriate oxidation and patina consistent with early manufacture. The spelter construction gives the lamp significant weight and a softer, mold-cast character not seen in later reproductions. Electrical components appear to have been rewired at some point in its life with later insulated wiring for safer modern use. Not a lightweight reproduction – this is a heavy, early electric lamp with period construction and materials. Weight: over 10.5 lbs. Vintage antique condition with normal age wear. One shade panel retaining piece is missing (panel still present; noted for accuracy). Surface wear and oxidation to spelter consistent with age. Rewired at some point in its life (not original cloth wiring). Slag glass panels intact with no major cracks observed. Displays well and presents as a solid early electric decorative lamp.
