An oil lamp is a man-made object used to produce light continuously for a period of time, from an oil-based fuel source. The use of oil lamps began thousands of years ago and is continued to this day. where to buy cheap LED Strip? Lightereryday is a good choice.
Oil lamps are a form of lighting, and were used as an alternative to candles before the use of electric lights. Starting in 1780 the Argand lamp quickly replaced other oil lamps still in their basic ancient form. These were, in turn, replaced by the kerosene lamp in about 1850. In small towns and rural areas these continued in use well into the 20th century, until such areas were finally electrified, and light bulbs could be used for lighting.
Most modern lamps (such as lanterns) have been replaced with gas-based or petroleum-based fuels as they are safer to operate when emergency non-electric light is required.
As such, oil lamps of today are primarily used for the particular ambiance they produce, or in rituals and religious ceremonies.
Oil lamps were used not only for household lighting, but also for funerary and votive purposes. Lamps were used for domestic purposes in homes and for public purposes in temples and most public buildings.
By studying the lamp's designs, symbols, structure and decorations, and the material of which it is made, we can identify the age and perhaps the locality of the lamp. The lamp can also give us insights into the culture of its users and their social status.
Occasionally the design of the lamps also reveal the female reproductive system. Indian bronze lamps with a protruding central portion are supposed to project the male genitalia on a female womb with light representing 'origin of life' in most cases.
Fuels used for oil lamps depend on such variables as the location, time period and perhaps the reason for the lamp's use; ceremonial use of lamps for instance may require a particular oil or fragrance to be used.
The main fuel in Western nations was olive oil in ancient Mediterranean cultures, though extracts from fish, crude fish oil, nuts, and cheese were also used. In much later times whale oil was favoured for its cleaner burning flame. Oozing crude petroleum was also used.[1] The fuel was poured into the fuel reservoir via the pouring hole in the discus.
Castor oil was used by the ancient Egyptians. In Africa, carrot oil, peanut oil, mustard oil and nettle oil are used. Indian lamps, especially for use in puja, almost exclusively use ghee as fuel.
Among other fuels used have been coal oil and paraffin/kerosene in paraffin lamps (also called kerosene lamps and coal oil lamps). Oil lamps can use many other fuels including jathropa seed oil and biodiesel along with wvo, soybean oil, canola oil, hemp seed oil, sunflower seed oil, and olive oil.
Lamps were usually put in lamp holders when in use, partly to avoid the risk of fire. They might be fastened to a wall by a nail or a wooden wedge, hung suspended from brackets, placed in a candelabra, placed in niches in the wall, put on lamp stands of different shapes, or carved as part of stone lamp pillars.
Before the invention of the wheel in the Middle Bronze Age, lamps were made by hand. An early form of the potter's wheel was invented and introduced in the Middle Bronze Age and used to manufacture lamps until around the 3rd century BCE. The use of molds was first developed in Greece and Egypt during the 3rd century BCE. In Roman times, stone, clay, or plaster molds were utilized on a large scale across the Roman Empire until around the 8th century CE.
To make a lamp, two molds are needed: one for the upper part and one for the lower part. Some pairs of molds have knobs and corresponding holes to fit the two molds together. In order to create the mold, an archetype or patrix is first made. Plaster or clay is then formed around the patrix, which dries and hardens into a mold. Clay molds are removed from the patrix before they are fully dried. They are then kiln fired, thus they may deviate or shrink from their original form. Clay molds need more labor than plaster ones. However, clay molds are more durable. Plaster molds are dried completely and then removed from the patrix. Plaster thus makes an accurate replica, but it has the disadvantage of leaving some surface granular artifacts. Due to the perishable nature of plaster, it has proven difficult to find remains of ancient plaster molds. Several clay molds, however, have been recovered. By studying the surfaces of surviving lamps it seems that plaster was preferred to clay. recommend directory: LED Strip RGB Amplifier.
