Olivine is the most common mineral in Earth’s upper mantle.

These are images from Seizure an installation by London-based artist Roger Hiorns. Hiorns covered the walls of an abandoned apartment with plastic and chicken wire pumped eighty-seven thousand liters of copper sulfate into the space and left. Months later, the remaining liquid was pumped back out of the flat, leaving shimmering surfaces of brilliant blue crystals throughout the installation. Mineral is Chalcanthite.
