The hand moulded facing brick with blue nuances
The facade bricks (non-perforated) have five sand covered sides and one side with possible oblong groove. The structure looks rugged with fine and irregular grooves in the sandy surface. The baking process takes place in a gas-heated tunnel oven under slightly reduced atmosphere.
The homogeneous mixture of accurately predefined 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 pitch-black with blue shades.
