How do I date a yellow glass lamp?

Examine the construction of the burner mechanism, the weight of the metal base, and the manufacturing technique of the glass body. Victorian pieces often feature heavy brass columns and hand-blown fonts, while 1930s examples lean towards geometric Art Deco silhouettes and streamlined glass shades. Look for registration marks, maker signatures on the metalwork, or specific threading on the burner collars that correspond to known nineteenth and twentieth-century manufacturing periods.

Were these lamps converted to electricity?

Many antique oil lamps undergo careful conversion to electricity to make them practical for modern domestic use. Wiring is typically routed through the original central column without destroying the antique burner components or the glass font. Collectors can find both professionally converted electric table lamps and intact, un-converted oil lamps that retain their original wicks and brass burners.

How do I clean an antique glass lamp?

Use a soft, dry microfibre cloth to remove dust from the glass surface and delicate metal mounts. Avoid submerging vintage metal components or using harsh chemical cleaners that can strip the patina from brass and silver plating. For the glass shade or reservoir, warm water and mild soap applied with care will lift grime without damaging the surface or any painted decoration.

What is the difference between vaseline glass and amber glass?

Vaseline glass contains uranium, giving it a bright yellow-green tone and a distinct fluorescence under UV light. Amber glass presents a warm, brownish-yellow or honey-coloured hue without the characteristic uranium glow. Both materials were utilised extensively across the Victorian and Edwardian periods for oil lamp fonts and decorative hanging shades.
