AI Appraisal Estimate

This is a vintage table lamp featuring a multi-paneled slag glass shade with a tulip or scalloped edge profile. The shade is constructed using traditional leaded glass techniques, likely copper foil, with a combination of textured green glass panels at the top and bottom and cream/amber marbled slag glass panels in the main body. The base is crafted from a cast metal, likely brass or a brass-finished white metal, showing a significant aged patina and dark oxidation, particularly on the neck and tiered circular base. The lamp stands approximately 18-22 inches tall. The shade consists of six main translucent panels with vertical streaks of white and yellow, framed by smaller emerald green textured glass diamonds at the points and rectangular panels at the crown. Condition-wise, the leaded seams appear intact, though the metal base shows heavy surface wear and some pitting consistent with late 20th-century production (circa 1970s-1980s revival style). A blue price tag is fixed to the central column. The craftsmanship reflects a mass-produced take on the Arts and Crafts or Tiffany style, characterized by the heavy solder lines and simple turned-metal base design.

I have examined the digital representation of the Vintage Slag Glass Tulip Shade Table Lamp. The item is a late 20th-century revival piece, likely manufactured between 1970 and 1985, mimicking the earlier Arts and Crafts movement. The shade utilizes copper foil construction with six marbled slag glass panels and textured green glass accents. While the glass remains structurally sound with no visible hairline fractures in the panels, the leaded seams show typical oxidation. The cast-metal base exhibits significant pitting and surface wear, which is characteristic of the zinc or white-metal alloys used in mass production during this era rather than the high-quality bronze or solid brass found in antique originals. Market demand for this specific 'Tiffany-style' revival remains steady for decorative purposes, though it lacks the rarity sought by high-end collectors. Similar pieces frequently sell in the $100 to $200 range at regional auctions and antique malls. The primary value-driving factor is the decorative appeal of the slag glass; however, the heavy patina on the base and commonality of the design limit its appreciation potential. Please note that an evaluation from images alone cannot verify the safety or functionality of the internal wiring. A full authentication would require an in-person physical inspection to check for manufacturer stamps (such as Bradley & Hubbard or Miller) on the weighted base, an examination of the socket type, and verification of the glass's chemical composition to rule out modern plastic resin substitutes. Provenance documentation regarding its original purchase would further refine this valuation.
