How do I convert these to electricity?

Most antique oil lamps and gasoliers can be adapted for modern electrical wiring by running a concealed flex through the existing central burner or column. Professional electricians carry out this work without damaging the structural metalwork or requiring the alteration of original external surfaces.

Were these originally for oil or gas?

Lighting fixtures from the nineteenth century were manufactured to burn either liquid fuel through a wick or coal gas piped directly into the building. Oil lamps feature removable metal fonts and burners, whereas gas fixtures utilise rigid iron or brass supply arms terminating in keyed gas cocks.

How do I clean period glass shades?

Wash glass components gently in warm water using mild soap, avoiding abrasive pads that can scratch delicate hand-painted decoration or soft lead crystal. Dry thoroughly with a lint-free cloth before reassembling the shade onto its brass gallery or fitter ring.

Are original glass shades marked?

Victorian and Edwardian glass shades rarely carry maker signatures or factory stamps, as most glasshouses relied on distinctive decorative styles and shapes for identification. Matching a shade to a base depends on the fitter size, glass colour, and period-appropriate manufacturing techniques.
