Buyers should inspect the internal wiring methods used during conversion to ensure they meet current safety standards.

How do I identify a Victorian crystal lamp?

Examination of the cut glass facets, metal mounts, and overall weight helps establish the period. Victorian pieces typically feature heavy lead crystal and solid brass or bronze components. Stylistic cues such as Classical Revival or French influence also assist in dating the lighting accurately.

What is the difference between glass and crystal?

Crystal contains lead oxide, which increases the density and refractive index of the material. This composition permits much sharper and deeper cutting than standard window or bottle glass. Lead crystal also produces a distinct ringing sound when gently tapped.

How should I clean a crystal lamp?

Delicate washing with lukewarm water and mild soap preserves the surface of the glass and metal mounts. Harsh chemicals can damage gilt decoration and antique brass finishes. Prisms and pendants are often removed individually for careful cleaning before reattachment.
