Miner Lamp (Large) coal model miniature made with deep mined coal looks absolutely fantastic, appealing very much to the someone who places great emphasis on owning unusual and quality products.

Early miners used tallow candles, made from animal fat, although they were smoky and gave little illumination. They had the advantage of being very cheap, and could even be eaten in an emergency. Sometimes the miners attached these to their hats with a soft ball of clay, or they attached them to the ground, a rock, or a ledge using clay or a metal spiked holder. Gradually, other more efficient forms of lighting took over.

Davy Lamp

The flame safety lamp was invented by Sir Humphrey Davy in 1815, to address the problem of explosions caused by naked flames coming in contact with flammable gases in mines. The Davy lamp was fuelled by oil or naptha (lighter fluid), and the wick was contained in a metal gauze cylinder. The underlying principle of the safety lamp is that the gauze cools any flame passing through it, so that the temperature outside the lamp is lower than the temperature required to ignite any surrounding flammable gas. If the lamp is placed in an explosive atmosphere, such as a mixture of air and methane gas as commonly found in a coal mine, the explosion that takes place when the flame contacts the gas is contained within the gauze mesh and does not cause a danger to the miners.

There were many manufacturers of Davy lamps, and many variations in the detail of their construction. The lamps normally had a cylindrical glass screen around the gauze, and a protective steel bonnet with air inlet holes. Early versions gave out less light than a naked flame candle, but designs improved so that by the 1930's some types were several times brighter than a standard candle flame.

The lamp provided a crude test for the existence of gases, as the flame changed shape or burned with a blue tinge in the presence of flammable gases. In addition, the lamp could be used to check for low oxygen levels or concentrations of gases such as carbon dioxide, as in these conditions the lamp flame would be extinguished. The lamp succeeded in reducing the incidence of explosions, but accidents still happened, such as when a lamp was dropped or broken.
