These 14th century relief tiles are made in England and Scotland. The decoration is either raised or counter-sunk and usually glazed in the same tones as mosaic tiles.
Those of you, who know me, know I have a tile fetish (probably easier to manage than one for shoes).  I love the natural ingredients from which tile is made; earth-dug clays, silica, sand and water. I also love the fact that clay can be transformed by the human hand into an object of enduring beauty. It can be squeezed and molded into any shape and applied to many surfaces.  And tile grids provide the opportunity to configure a square or rectangle into impressive wall patterns.
