What periods do these lamps come from?

The pieces span the nineteenth century through the early decades of the twentieth century. They encompass Victorian, Art Deco, and revival periods inspired by earlier French monarchies. Craftsmen during these eras frequently adapted classical shapes from antiquity, reinterpreting them through the prevailing taste of the late eighteen-hundreds and nineteen-twenties.

How were oil lamps converted into table lamps?

How do I distinguish marble from onyx bases?

Marble displays distinctive veining and a crystalline structure formed from metamorphosed limestone. It generally feels cooler to the touch and heavier in hand.

Where should I place an urn lamp in a room?

Positioning them away from high-traffic edges protects the protruding ormolu mounts and delicate porcelain handles from accidental bumps.
