Luminescent mantle
A technical innovation of the 19th century is the incandescent mantle. A finely woven gauze was covered by particular salts; a kerosene flame causes it to glow. Each year on the second Sunday in advent such kerosene lamps illuminate the booths of the charity Christmas market in Rixdorf. The Technisches Hilfswerk do not only tend to these lamps; without the enthusiasm of these volonteers the entire Christmas market would not take place. Our thanks go out to all of them!
