How do I date a glass lamp?

Dating relies on identifying material combinations, manufacturing techniques and stylistic markers such as Victorian Corinthian columns or Art Deco geometric bases. Examining the mountings and the type of crystal provides further clues to the decade of manufacture. Earlier pieces often incorporate brass oil lamp conversions, whereas 1930s examples lean towards streamlined mushroom shapes and modernist cubic glass forms.

Are these lamps safe for modern desks?

Most antique and vintage lamps require rewiring or PAT testing by a qualified electrician to ensure they meet contemporary safety standards before daily use. Retaining original brass fittings and switches is standard practice, but internal wiring should be updated to handle modern electrical currents safely.

What is the difference between glass and crystal?

Crystal contains lead oxide, which increases the weight, clarity and refractive index of the material compared to standard glass. This high lead content allows artisans to cut deeper, sharper facets into the surface. Lamps made from lead crystal catch and disperse light more intensely than ordinary glass alternatives.

How should I clean a cut crystal lamp?

Cleaning requires mild soapy water and a soft cloth to remove dust from the intricate facets without damaging the surrounding brass or chrome mounts. Harsh chemical cleaners must be avoided to protect the vintage metal finishes. Careful drying prevents water spots from forming within the deep cuts of the crystal.
