A dark hand-moulded facing brick
The Meuse Brick is part of the Obscuro range of Nelissen Brickworks. This hand-moulded facing brick is made from Löss from Limburg, extracted from the plateau of Kesselt in the Meuse valley. Then the stone is upgraded with raw materials from the Volcanic Eifel. The non-perforated brick is covered with sand at five sides and provided with an oblong sloping groove on one flat side (frog, group 1). The structure of the Meuse Brick is characterized by a rough appearance with fine and irregular grooves in the sandy surface. The baking process of this brick is done in a gas-fired tunnel kiln under a slightly reducing atmosphere.
The dark brown colour of the brick is obtained by the homogeneous mixing of manganese dioxide with grey-red baking loam. The colour shades vary from grey-yellow to red-brown.
