Just Add Wicks and Floats.
The kind of oil lamp that can be ready for use in a flash: Fill a suitable vessel with water and add a thimbleful of pure vegetable oil. Then push a wick into a cork float (can repeatedly be used) and place it just on the surface of the oil before igniting the wick. With just 10 ml of oil, the floating wick will burn for two hours, with one litre of salad oil, around 200 hours; all this with virtually no soot, no odour, and only as much carbon dioxide as is produced by the growth of plants. When the wick is exhausted, it is simply replaced. We offer short night light wicks made of cotton yarn, encased with paraffin and beeswax, as well as three-leafed cork floats by Glafey of Nuremberg. Both have been produced since 1867 and, as the manufacturer had already trumpeted at the beginning of the 20th century, they are "a must in every reputable establishment." The fact that they still exist after more than 150 years is a guarantee of their quality.
