Every spring produces a unique stone quality, which depends on the local geology of the ground. Depending on the amount of iron oxide, the material is white, red or yellow in colour. The density also differs. The natural geological processes strengthen and thicken the fragile structure randomly.
Inspired by the growth of stalactites, Laura Lynn Jansen and Thomas Vailly have found a way to ‘grow’ stone in different forms. Their design series, CaCO3 Stoneware, consists of objects grown around structures drop by drop. The fragile skeleton, a 3D-printed structure, undergoes a petrification process that lasts many weeks in specially chosen thermo-mineral springs with a high calcium carbonate content, also known as CaCO3.
