How do I date a lamp?

Examine the burner mechanisms, base materials, and stylistic motifs to determine the period of manufacture. Victorian pieces often feature heavy brass columns and floral painted fonts, while Art Deco items display geometric lines. Comparing the construction methods of the brass work and the formulation of the glass helps narrow the decade. Patents stamped on burners also provide reliable manufacturing dates.

Were these lamps converted to electricity?

Many period oil lamps and candle-lamps undergo conversion to electricity for modern household use. This process typically involves running wiring through the original central column while retaining the historic shade and font. Original oil lamp components such as burners and collars are frequently preserved during conversion. Buyers should inspect the wiring method to ensure it respects the physical integrity of the antique.

What is a duplex oil lamp?

A duplex oil lamp utilises a twin-wick burner system designed to provide stronger illumination than single-wick variants. These burners were standard on many quality nineteenth-century lighting pieces. The mechanism allows the user to control two flames simultaneously through a pair of thumbwheels. This type of burner is frequently encountered on larger Victorian table lamps.

How should I clean painted glass shades?

Clean painted glass shades gently with lukewarm water and a mild detergent using a soft cloth. Avoid harsh scrubbing or abrasive cleaners that can damage the hand-painted enamel decoration. Carefully dry the glass immediately after washing to prevent water spots. Painted surfaces require particular caution to preserve the original pigment.
