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 brick has a salmon-pink base, with the hues ranging from beige-pink to brownish red as a result of the treatment and sanding of the typical Kesselt red baking lössial clay with fine-grained sand.
The colours shown are a near reflection of reality.
