How do I convert an oil lamp?

Most period oil lamps convert to electricity by running a cord through the existing burner collar without altering the exterior metalwork. This preserves the original reservoir and burner components while allowing modern bulb fittings. Professional rewiring ensures the vintage brass components are properly earthed and safe for daily domestic use. Retaining the original mechanical parts maintains the historical integrity of the piece.

What burns in a duplex lamp?

Duplex burners utilise paraffin or kerosene oil via dual flat cotton wicks housed beneath a glass chimney. These systems provided superior illumination compared to single-wick predecessors during the nineteenth century. Modern owners generally display these as decorative objects rather than active fuel burners. The twin wick wheels remain functional on many surviving examples.

How are brass columns dated?

Dating relies on stylistic clues, manufacturing techniques, and patent marks stamped onto the brass collars or burner mechanisms. Corinthian and Gothic Revival motifs dominated mid to late nineteenth-century production. Heavier cast bases and sharp classical detailing typically indicate earlier Victorian manufacture. Lighter, more stylised forms often point towards the subsequent Edwardian period.

Are original glass shades rare?

Original hand-blown opaline, cranberry, or etched glass shades remain scarcer than the metal bases due to their fragility. Finding a matching period shade substantially enhances the character of a table light. Many surviving pieces lost their original glasswork over generations of domestic use. Replacement shades are selected to match the period proportions and fitter sizes.
