A hand-moulded facing brick with a beautiful combination of brown and grey

Muria is a hand-moulded brick from the Obscuro range of Nelissen Brickworks. This brick is made from Löss from Limburg. The stone is extracted from the plateau of Kesselt in the Meuse valley. Then the brick is revalued with raw materials from the Volcanic Eifel. The non-perforated facing brick is sanded on five sides. Muria is provided with an oblong sloping groove on one flat side (frog, group 1).

The structure of the Muria is rugged with fine and irregular grooves in the sandy surface. The baking process of these hand-moulded bricks is done in a gas-fired tunnel kiln under a slightly reducing atmosphere. By the homogeneous mixture of a precise percentage of manganese dioxide with loam, a grey-brown brick is obtained. The colour varies from mainly grey to dark grey.
