This hand-moulded facing brick is made from Limburger löss clay from the Kesselt tableland in the valley of the Meuse and revalue with raw materials from the Volcanic Eifel.
The facade bricks (non-perforated) have ﬁ ve sand covered sides and one oblong groove. The structure looks rugged with ﬁ ne and irregular grooves in the sandy surface. The baking process takes place in a gas-heat- ed tunnel oven under slightly reduced atmosphere.
The homogenous mixture of accurately pre-defined proportions of manganese oxide with grey-red baking lössial clay is responsible for the black colour of the brick. The colour ranges from mainly charcoal to pitchblack with blue shades.
