Olive oil lamps continued in wide use in countries around the Mediterranean Sea well into the 19th century, with the lamps being mass produced out of metal (most commonly brass or bronze), but otherwise little changed in design from lamps of some 2,000 years earlier. In 1780 the Argand lamp was invented and quickly replaced the ancient form. It was, 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. The light given by an olive oil lamp is significantly brighter than a candle, but significantly less than the Argand lamp or the kerosene or paraffin burning lamp.
Structure & Function
Oil lamps were used not only for lighting, but also for funerary and votive purposes. Lamps were used for domestic purposes in homes and for public purposes in temples and 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.
Oil lamps were made from a wide variety of media like gold, bronze, silver, stone and terra-cotta. The most commonly used material was fired clay; many terra-cotta and bronze lamps have been unearthed. In most cases, the production and distribution of lamps was local, but in some instances they were produced by factories and exported to different areas.
The usual size of a terra-cotta oil lamp is 7-10 cm in length and 3 cm in depth, with the walls being around 0.5 cm thick. Lamps with more than one nozzle are usually larger in size.
Components
The following are the main external parts of a terra-cotta lamp.
Shoulder;
Pouring hole;
- The hole through which fuel is put inside the fuel chamber. Its width ranges from 0.5-5 cm in general. There may be single or multiple holes.
Wick hole, and the nozzle.;
- It may be just an opening in the body of the lamp, or an elongated nozzle. In some specific types of lamps there is a groove on the superior aspect of the nozzle that runs to the pouring hole to collect back the oozing oil from the wick.
Handle;
