Camphine was the trade name of a purified spirit of turpentine formerly used for lamps, generally prepared by distilling turpentine with quicklime. Camphine gives a very brilliant light when burned in a lamp, but, to prevent smoking, the lamp must have a very strong draught. To achieve this special lamps were constructed, so called Vesta lamps.
