Dewar Manufacturing Co. 'ITP' Carbide Mine Lamp, c.1915

Story

In the dark, dangerous depths of American coal and metal mines, light was the difference between life and death. Before the widespread use of battery-powered electric lamps, miners relied on these ingenious devices that mixed water with calcium carbide to create flammable acetylene gas.

Maker / Origin

The Dewar Manufacturing Company of Brooklyn was a titan in the mining light industry during the early 20th century.

Condition & Value

The brass shows a heavy, honest patina and some surface oxidation consistent with age and subterranean use. The reflector appears intact, and the brass identification plate is remarkably legible with clear patent dates, which is a major plus for collectors. The presence of the original mounting hook adds to its completeness.
