This lovely vintage blue Lampe Bergere comes directly from France. It is a glass bottle with a wick inserted in the top that will disperse a scented oil that is put in the bottom of the bottle. Both the top and the bottom are marked, the bottom adds Paris. The lamp is in very good vintage condition, it is used but the wick is still white and the glass base and other components are free from damage. There are some marks on the top showing it was used, but that is a natural byproduct of this lamp. It measures 3 ¾" square and is 5 ¾" tall. A fragrance lamp, also known as a perfume lamp, effusion lamp or catalytic lamp is a lamp that disperses scented oil using a heated stone attached to a cotton wick. The catalytic combustion wick was originally developed in the 19th century for use in hospitals and mortuaries. A Frenchman named Maurice Berger was the first to receive a patent, (in 1897) and the company he founded, Lampe Berger, is the oldest worldwide manufacturer of the device though there are a growing number of companies making such lamps. The lamps are sold on the premise that molecules that cause bad smells are inherently unstable and the fragrance lamp's flameless, low-temperature catalytic combustion speeds up the decomposition process, converting odor molecules into harmless substances (such as carbon dioxide and water). While the lamps are no longer considered effective for use in hospitals, they have remained popular as air fresheners.
