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 dark brown colour of the brick. On top of white sand, white powders are applied and fired in a scattered way, in order to obtain the grey-white sediments, which results in a very light shade. Through sintering of the brick, the different nuances of colour are obtained. The colours shown are a near reflection of reality
