Two miners lamps, 10 inches tall. The safety lamp, a much larger lamp that could not be worn, but had the advantage of a sheltered flame that would not ignite any flammable mine gasses. In the early 1820s Sir Humphry Davy discovered that a flame enclosed in mesh would not ignite flammable gasses. The fine metal mesh served to cool the flame so that it no longer had the energy required to ignite the flammable gas in a mine. Mine safety lights eventually developed to include a glass enclosure around the flame for better lighting and metal bonnet to better protect the flame. State: City: HWAC#: 48657 Date:
