How do these lamps work?

These lamps draw liquid paraffin up through a woven fabric wick via capillary action. Lighting the exposed top of the wick produces a steady flame protected by a glass chimney. A metal burner mechanism controls the flame height using a small thumbwheel. Turning the wheel raises or lowers the wick to adjust the brightness.

Can I still burn oil in them?

Many people continue to burn modern lamp oil or liquid paraffin in these vessels for atmospheric lighting. Ensuring the wick and burner mechanism are clean and sound is essential before use. Some buyers prefer to convert them for electricity to use them safely as bedside or table lamps. Conversion typically avoids drilling the main body by running wiring through the burner collar.

How do I clean the brass?

A gentle wipe with a soft, dry cloth removes dust without disturbing the aged patina. Avoid harsh chemical polishes that strip the historic character from the metal surface. Glass shades and chimneys can be washed separately in warm soapy water. Ensure every glass component is completely dry before placing it back on the metal collar.

Are these pieces Victorian or Edwardian?

The listings span from the mid-nineteenth century through the Edwardian era and into the early twentieth century. Victorian examples often feature ornate Corinthian columns or coloured glass fonts. Edwardian pieces tend toward simpler domestic forms or softer opaline shades. Examining the metal casting style and glass decoration helps determine the specific period.
