Living Stone

Some buildings are not as static as they appear. From the cracks and crevices you can see tiny formations emerging. This is urban dripstone forming from the concrete structures. These stalactites and stalagmites are formed by calcium and the Co2 present in the air. Collaborating with the University of Koblenz-Landau I recreated this growing rock in the lab, developing a technique that forms these sculptures in hours instead of millenia. I want to highlight these natural formations and try to decode this process of growing stone, creating growing buildings. This reaction uses Co2 and smog particles from the atmosphere to solidify, which could very well have a much more important role than we realise now.
