History of Kerosene Lamps

History of Kerosene Lamps


After the invention of modern oil lamps and the production of kerosene about 1800, population needed a way to use these lamps to do work outside. The oil lamps used a glass globe and wick to operate the amount of air flow colse to the wick, and protect the flame. But there was much work to be done outside, where these lamps were actually broken. Therefore a much stronger, more protected source of light was needed. So came the introduction of the kerosene lantern, also known as a hurricane lantern. This is a more rugged version of the kerosene lamp, which is designed to be portable. They consist of a metal base, which holds the fuel, and side tubes which securely hold the glass globe to prevent breaking.

These lamps had numerous uses in the early 1800's straight through the 20th century. They were used for lighting homes, and barns, to light horse drawn carriages, on ships, hasten cars, and even early automobiles.

There were distinct kinds of kerosene lanterns made. One was the dead flame lantern. These were designed to eliminate or minimize the draft which reached the flame. These are also known as non-tubular lanterns. They consisted of a series of baffles inside the top, above the globe, and a series of lowest draft holes, that were positioned so no top draft, or wind could blow directly on the flame. These were often used by the railroads as signaling lights.


Another type of kerosene lamp was the tubular lamp. These include a ducting theory to stabilize and enhance the draft of air reaching the flame, creating a stable, wind defiant flame. They are added divided into the "hot blast" and "cold blasts" styles.

The "hot blast" lanterns are constructed to contribute air into the base of the lantern, which is heated by the flame. A measure of the hot air rises into the canopy over the globe, and is pushed by a downdraft straight through the side tubes to the air chamber below the burner supplying the flame. Hot blast lanterns produce a yellow flame.

The "cold blast" lanterns are constructed so the contribute of air straight through the side tubes, does not mix with heated air from the flames. The flame is supplied with fresh air, both straight through the globe plate and the side tubes. This produces a white flame, and twice the volume of light as a "hot blast" lantern. The most paramount maker of tubular lamps, R.E. Dietz, still manufactures lamps today, although his company has moved to Hong Kong and China.

The use of kerosene lamps decreased during the depression. Today most uses for kerosene lamps are supplied with flash lights, and outdoor lights. Kerosene lamps are often collectors items.

History of Oil Lamps

History of Oil Lamps


Oil lamps are a fabulous way to light your evenings. They bring a nostalgic feel to any setting. They are used in log cabins, historical sites, lodges, hotels, museums, and of course underground residences. They bring the past to life, and are fabulous if the power goes out.

For ancient man, torches, candles, and crude lamps restricted their activities to daylight hours. It became critical to try to light the darkness. Oil lamps have been nearby since ancient man used hollowed out stones, or seashells filled with animal fats or pine pitch to light the darkness. The word lamp is derived from the Greek word lampas, meaning torch. As time passed the oil lamp evolved from bowl to saucer shaped with a nozzle or spout which held the wick.

In the time of the Greeks and Romans, lamps were often made of terra cotta, or clay, and used olive oil or animal fats. The Romans probably made the oil lamp the first mass produced object in history. Lamps were also made of bronze, stone, and alabaster, and were often elaborately decorated.


Oil lamp develop did not turn significantly until the 1700's when Swiss chemist, Aime Argand, invented a lamp using a round burner, and a circular wick. Flame was also enhanced by the use of a glass chimney, which protected the flame and controlled the air flow. Lamp oil also evolved. Early fuels included animal fats, pine pitch, olive oil, and beeswax. Whale oil was a tasteless source of lamp oil until the early 1800's when whales became scarcer, and whale oil became very expensive.

In the mid 1800's a process was industrialized for converting coal into coal oil. The product was called kerosene. The early process was less expensive than whale oil, but smoked, and had a disagreeable odor. The process has since been refined, and the cleaner oils used today have virtually no smell and smoke. In the 1850's a process was patented to distill a lubricant call Paraffin oil, which is a petroleum derivative.

Lamp evolution and the hunt for cleaner burning fuels prolonged into the 1800's and industrialized most of the lamps we recognize today. Of course the introduction of electricity in the late 1800's slowly reduced the use of oil and oil lamps as a main source of light. That doesn't mean the production of oil lamps stopped after the allinclusive use of electricity. Oil lamps remain very beloved today, and are still a major source of light in less industrialized parts of the world.
