Mining oil lamp

In the past, miners' working time was not standardized, there were no appropriate mechanisms that could determine it precisely, especially in specific underground conditions. The length of a mine shift was therefore determined by the amount of tallow burned. At your own light, you also had to go out of the mine to the surface, as miners say - out into the world. This was not easy, because in the draughts of the mine the lamps often went out. At that time, the direction was marked by numerous chapels, in which lamps were on duty to illuminate objects of religious worship.
