The kerosene lamp (widely known in Britain as a paraffin lamp) is a type of lighting device that uses kerosene (British “paraffin,” as distinct from paraffin wax) as a fuel. This article refers to kerosene lamps that have a wick and a tall glass chimney. The first description of a simple lamp using crude mineral oil was provided by al-Razi (Rhazes) in 9th century Baghdad, who referred to it as the “naffatah” in his Kitab al-Asrar (Book of Secrets). Modern versions of the kerosene lamp were later constructed by the Polish inventor Ignacy Łukasiewicz in 1853 Lviv, and by Robert Edwin Dietz of the United States at about the same time. The question regarding the primacy of these two inventors’ versions of the lamp remains unresolved.
