An Engine-Turned Lamp Base is a lamp featuring decorative geometric patterns mechanically engraved onto its metal surface using an engine-turning machine. The technique produces finely repeated circular or wave-like designs that reflect light beautifully and became particularly popular during the late Victorian, Edwardian and Art Deco periods. Antique engine-turned lamp bases are admired for their precision and elegant finish. *Related Terms*\ Art Deco Lighting, Brass Lamp, Engine Turning, Metalwork, Table Lamp.
