How do I operate a duplex burner?

The twin wicks are adjusted via separate thumbwheels on the burner gallery. Raising the wicks evenly allows them to be lit to produce a bright, steady flame. Extinguishing the flame involves turning the wheels down until the wicks drop below the metal slots, cutting off the air supply.

What fuel do these lamps require?

These fixtures were originally designed for paraffin or kerosene illumination. Modern usage typically involves burning standard lamp oil. Care must be taken to use clean, refined fuel to prevent soot accumulation on the glass shade.

How do I date a brass oil lamp?

Dating relies on stylistic indicators such as column orders, burner patents, and glass colours. Victorian examples often feature heavy Corinthian or reeded brass columns. Edwardian and Art Nouveau variants introduce softer floral motifs and distinct hand-blown shade profiles characteristic of the early twentieth century.

Can these lamps be converted to electricity?

Many collectors choose to wire these pieces for modern lighting while preserving the original burner and collar components. This allows the lamp to function as a table lamp. Professional conversion ensures the wiring passes safely through the central column without damaging the antique brass structure.
