Oil-Wick Cap Lamp

Description
This oil-wick cap lamp was made by John Dunlap of Pittsburgh, Pennsylvania during the second half of the 19th century. The oil-wick cap lamp was first invented in Scotland in 1850 and in use until the 1920’s. The font contained a mix of fat and oil for fuel, and a wick was inserted into the spout. The resulting flame was much brighter and more efficient than the candles it replaced. The hook enabled the lamp to be worn on a cap. This lamp has a double-spout, indicating that it could have burned "Sunshine" fuel, a mixture of paraffin wax and 3% mineral oil produced by the Standard Oil Company. Often called a "Sunshine Lamp," the outer spout served to insulate the wick in the inner spout, thereby conducting enough heat to melt the wax.
