D137

D137 is waterstruck and blue-tempered, i.e. it is fired in low-oxygen conditions. It has four equally usable sides and a rough, changing surface. It is made of red clay and has a varied play of colour that combines light- and medium-grey shades with pink, golden and green tones. Some of the bricks cover the whole spectrum from pink to grey. D137 also has a clear, clean look.
