Kerosene gas lamp : It is a lighting device based on liquid fuel , at high pressure , mainly kerosene , used in times when electricity was not yet available , especially in rural areas. Its shape is varied and there have been, over the course of history, different models whose designs were related to the application and the place where they were to be used.

Origin of lamps
The earliest forms of lamps were burning sticks or containers filled with embers . They were then used to light long-lasting torches , consisting of bundles of branches or chips of resinous wood , tied and soaked in tallow or oil to improve their combustion qualities. The exact origin of the oil lamp , the first authentic lamp, is unknown , but it was already widely used in Greece in the 4th century BC. The first lamps of this type were open containers made of stone , clay , bone or shell , in the ones that burnedtallow or oil . Later they became partially closed sebum or oil deposits, with a small hole in which a linen or cotton wick was placed . The fuel rose through the wick by capillary action and burned at the end of it. This type of lamp is also called a lamp . Some large Greek and Roman lamps had numerous highlights to give a brighter light . In northern Europe the most common form of lamp was an open stone vessel filled with tallow, into which a wick was inserted. The Inuit (Eskimos) still use such lamps.
The appearance of the first lamps of this type dates back to the time when oil began to be used commercially (year 1859 ). The first manufacturer is presumed to be Ignacy Łukasiewicz , a Polish inventor who adapted lamps that used to be based on whale oil , which until that time, the mid-19th century , was the main fuel for lamps, a material that was completely replaced by kerosene , cleaner, cheaper and safer than the previous one.
At the end of the 19th century , almost all the existing forms of lighting gave way to incandescent electric lamps in a general way. However, in some rural areas, kerosene or incandescent gas lamps continue to be used to a limited extent .
In it, the fuel tank is hermetically closed, which has a piston with which air is pumped inside, producing high pressure. By opening the shut-off valve, high pressure kerosene is forced through a small hole where it decompresses and gasifies. This gas fills a sachet of asbestos cloth, called a shirt or spark plug, which temporarily holds it to cause ignition. With this type of lamps an intense and white light is achieved, which covers larger spaces and provides more powerful lighting.
For the safe use of these devices, it is important to know how to regulate the pressure applied to the fuel tank, and (taking into account that said tank has a small screw-in valve for discharge of high pressures that could be generated); Be vigilant in case pressure needs to be released in view of the danger that it could explode and cause a serious accident .
Nowadays these lamps are not considered too practical, since there are other more modern and effective lighting methods to obtain light ; However, they are used in cases of emergency due to lack of electric current , or in places where it does not reach, such as in rural , uninhabited or difficult to access areas.
