Tiles in Solnhofen Plattenkalk or Solnhofen limestone salvaged in the 1950s extension of the Solvay building in Brussels. The stone was quarried in the German state of Bavaria and is commonly known as ‘Jura’, referring to the geological age of the limestone deposit. These tiles are not sawn but cleaved, thus beautifully revealing the texture of the stone. The darker imprints are often mistaken for fossils, but are oxidations of manganese that have a characteristic treelike or dendritic pattern. Dimensions: 15 cm x 30 cm x 0,7 cm. Sold per square meter.
