Oysters are increasingly popular as a delicacy, but they are also cultivated for being excellent natural water filters. Marjolein Stappers investigated yet another interesting feature of these versatile creatures. Struck by the beauty of their shells after savouring them at a restaurant, and noticing how they were thrown away as garbage, she came up with the idea for Oesterplat. She started to collect the empty shells from restaurants and found a way to turn them into something more durable. The result is an elegant tile collection made of concrete, marble and… oyster shells, showing their mother-of-pearl shine as newborn fossils.
