Description

The brick has a grey base, with colours ranging from silver grey, beige grey to mouse grey. The different structures are the result of sawdust and white, fine-grained sand. Through sintering of the brick, the different nuances of colour are obtained. The melting process of additives during the baking process causes irregular glazing on the straight side of the facing brick: this is what we call sintering. This sintering can lead to bricks sticking together and being packed this way. Tapping the bricks lightly will arrange for them to loosen again. Bricks, in which a small or larger clay shell loosens because of this, can simply be turned and processed with the other side, when not wanted in the area of view. These phenomena are typical for sintering and are contributory to the character of the brickwork with sintered bricks.

Pressure

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.
