How do I clean an old glass shade?

Remove the glass component from the metal frame before washing it in warm, soapy water. Avoid harsh abrasives that can damage pressed textures or hand-painted details. Dry the glass thoroughly with a soft cloth before reattaching it to the brass or chrome mountings.

Are these lights compatible with modern wiring?

Many vintage luminaires are rewired to meet contemporary electrical standards while retaining their original exterior components. A qualified electrician should inspect the internal fittings before installation. Ceiling fixtures often require specific mounting brackets to support the combined weight of the metal and glass.

What is the difference between opaline and frosted glass?

Opaline glass is manufactured with specific chemical agents that create a dense, milky-white appearance with soft light diffusion. Frosted glass achieves its translucent quality through acid-etching or sandblasting the surface of clear glass. Both treatments were favoured in the interwar period to soften the glare of electric bulbs.

How do I identify a French ceiling light?

French fixtures often feature distinctive signature etchings on the glass shades alongside characteristic geometric or floral moulding. The metalwork frequently employs sophisticated chrome or brass configurations that emphasise symmetrical lines. Documentation or recognisable glass signatures help confirm the origin of these pieces.
