How do I adjust the height on these lamps?

Articulation typically operates through sliding stems, counterweighted arms, or pivoting joints that permit directional positioning of the shade. Heavier models use internal springs or external keys to secure the desired angle and height.

Were these lamps originally electrified?

Many surviving examples date from the transition between oil, gas, and electricity, leading to original adaptations or later conversions for domestic use. Some pieces retain original switch mechanisms, fabric-covered cords, or fittings suited to specific period standards.

How do I distinguish an Edwardian model from an Art Deco one?

What maintenance do antique metal lamps need?
