Runö Warm Grey Brushed is a porcelain stoneware with a limestone appearance in a matt slightly structured surface. Runö is very true to nature with fossil-like details and beautifully varying tone differences between the tiles. Inspired by the stone that is mined along the limestone belt that stretches from Öland, under the Baltic Sea and the old Swedish countryside on the islands off the coast of Estonia, and further through Tallinn up to St. Petersburg.  The limestone, which is marketed under several names, such as Baltic Grey & Reval Limestone, has been mined along this line for generations and has been used in buildings throughout Scandinavia.
