Andrzej Danel at the Agricultural University of Kraków grew this large copper(II) sulfate crystal over the course of a few weeks. Danel was inspired by Roger Hiorns’s 2008 art installation “Seizure,” for which the artist pumped 75,000 liters of a copper(II) sulfate solution into an empty London apartment, allowing the compound to crystallize and coat the walls and ceiling in shimmering blue crystals. Danel says he didn’t have a big enough beaker for 75,000 liters; instead he used a 750 mL beaker to create this crystal, which he has dubbed “My Precious.”
