Lucas Leffler lives and works in Brussels. The artist, a graduate of the Royal Academy of Fine Arts in Ghent, produces in limited series unique, non-reproducible, identical images from the mud of the « Silver River. » This stream is so nicknamed after the Agfa-Gevaert photographic paper factory near Antwerp polluted its bed by dumping sludge containing silver salts into it. After the first pioneer workers who secretly extracted the silver from this sludge in the 1930s, Lucas Leffler is also digging to try to find traces of silver and produce his own photographic emulsion. The Zilverbeek project is at the same time a performance, a visual experiment and the conquest of a Grail. Ziverbeek’s works have recently entered the collection of the Antwerp Museum of Photography (FOMU), that of the Elysée Museum in Lausanne and in numerous private collections
