Overview

A classic 'slag glass' or 'caramel glass' table lamp featuring a six-panel curved shade encased in an intricate cast-metal floral overlay.

Story

In the first decades of the 20th century, the American home was undergoing a radical transformation as the 'Electric House' became the new standard of modern living.

Maker / Origin

While often unsigned, lamps of this quality were typically produced by renowned American firms like Bradley & Hubbard of Meriden, Connecticut, or the Miller Lamp Company.

Condition & Value

The glass panels appear to be original and free of major heat cracks, which is vital for value. The metal has a deep, aged patina that should not be polished away, as it confirms the item's antiquity. Any hidden cracks in the glass or breaks in the delicate metal filigree would reduce the value by approximately 30%.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

Value Drivers

  • Strong maker attribution with credible period details
  • Better-than-average condition for the category
  • Broader demand rises when presentation and finish feel intact

Concerns

  • Decorative-only demand limits the ceiling
  • Surface wear or missing provenance can compress the range fast
  • Regional sale lanes often underperform specialist venues

Best Venue
