How do I identify a genuine period lamp?

Examine the materials, wiring access points, and construction methods for period-appropriate brass, heavy cast iron, or hand-blown glass. Maker signatures or stamps on the metal base or glass shade provide further confirmation. Compare the switch mechanisms and cord exits against standard manufacturing practices of the interwar decades. Heavy patination on unlacquered brass and copper also indicates age.

Can these lamps take modern electrical bulbs?

Most desk and table lamps accept standard modern screw or bayonet bulbs once checked by a qualified electrician. Care must be taken with wattage limits to protect delicate vintage glass or fabric shades. Rewiring older fixtures preserves the original metalwork while ensuring household safety standards are met.

What maintenance do glass shades require?

Dust frosted, opaline, or mirrored glass gently with a dry microfibre cloth to avoid disturbing aged surfaces. Avoid harsh chemical cleaners that might strip hand-painted details or lacquer. Hand-painted glass and mercury mirrored finishes demand particular care during cleaning to preserve their reflective or decorated layers.
