The hand moulded brick that ensures a good balance.
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 predetermined proportions of manganese oxide within the loam is responsible for the light grey colour of the brick. The colours range from silver grey, beige grey to mouse grey interspersed with grey, black and blue shades.
