Argand Lamp, 1784
Lamp with glass chimney and circular, hollow wick designed by Argand in 1784 that increased the amount of illumination. The Argand lamp is a home lighting oil lamp producing a light output of 6 to 10 candela which was invented and patented in 1780 by Aim̩ Argand. Aside from the improvement in brightness, the more complete combustion of the wick and oil required much less frequent trimming of the wick. The Argand lamp had a sleeve-shaped candle wick mounted so that air can pass both through the center of the wick and also around the outside of the wick before being drawn into cylindrical chimney which steadies the flame and improves the flow of air. Early models used ground glass which was sometimes tinted around the wick. An Argand lamp used whale oil, colza, olive oil or other vegetable oil as fuel which was supplied by a gravity feed from a reservoir mounted above the burner.
