![]() ![]() ![]() It was built in 1680, and the brazier, in which the fire was burnt, is still in existence. One of the earliest known coal-fire towers to be fitted with a lantern is to be found on the island of St. The lanterns were not always a success as the glazing became blackened, and in a number of cases they were removed. This was a great problem, because it was precisely when the wind was blowing toward shore that the most brilliant light was needed, and the most danger to shipping was present.Īt first these fires were burnt in the open, but later they were enclosed by a lantern provided with a ventilating flue in an attempt to carry away the smoke, which would form around the fire and frequently obscure the light. When a strong wind blew off the land toward the sea, the light on the seaside became quite bright, but when the wind came from off the water the side of the fire facing the sea would be quite dark, while the land side of the fire was bright, yet useless. ![]() The quality of the light from brazier coal fires varied considerably with weather conditions. The first English lighthouse to use mined coal was Dungeness in 1616, and its coal-fired brazier consumed as many as 400 tons of coal per year. While in other countries, the governments accepted the total responsibility for building and maintaining the warning lights. Patents were granted to certain individuals for the upkeep of beacons in England and Scotland. These beacons were maintained both by public and private enterprises. They were often unreliable because of the variability between burning well, with lots of flame and therefore light, or burning poorly with little flame or much smoke obscuring the light. The early mariner’s warning lights consisted chiefly of open fires and later of fire beacons maintained on a grate or in an iron basket known as a brazier and shown from an elevated location or platform near the coast. This story will take you through the history of illumination methods in lighthouses. Even the oil lamp began in simplicity and evolved into a machine with multiple wicks, clockwork oil pumps, specialized chimneys, hydraulic, pneumatic, and other variants. Lighthouse illumination began with simple wood fires and progressed through generations of other methods. The ingenuity of man is truly amazing and this can easily be seen in the odd collection of techniques used for the illumination of lighthouses across the centuries. ![]()
