How do I clean a vintage white glass shade?

Wash the glass gently in warm, soapy water using a soft cloth to remove dust and residue. Avoid harsh abrasives that might scratch the surface or damage hand-painted details. Dry the shade thoroughly before reattaching it to any metal fitting or lamp base.

Are these shades suitable for modern electric bulbs?

Many of these shades can be adapted for modern electrical pendants or table lamps using standard fitter galleries. Ensure the bulb wattage matches the thermal limits of historical glass. Consult a qualified electrician to check that older brass or metal fittings meet current safety standards before use.

How can I tell Victorian shades from later pieces?

Victorian examples often feature heavier brass oil lamp collars, hand-crimped frills or delicate painted floral motifs. They typically accompany brass or ceramic lamp bases from the late nineteenth century. Twentieth-century pieces tend toward smoother geometric forms, such as Art Deco cones or industrial moonstone pendants.

What is the difference between opaline and milk glass?

Opaline glass is a refined, semi-translucent material that diffuses light with a characteristic fire or depth. It was widely utilised in nineteenth and early twentieth-century decorative lighting. Milk glass is generally denser and fully opaque, appearing in a broader range of utilitarian kitchenware and later decorative items.
