A hand-moulded brick with dark features

Moreno of Nelissen Brickworks is a non-perforated hand-moulded facing brick. The brick is sanded on five sides and provided with an oblong sloping groove on one flat side (frog, group 1). This brick is manufactured by Nelissen Brickworks from Löss from Limburg. The facing brick is extracted from the plateau of Kesselt in the Meuse valley and revalued with raw materials from the Volcanic Eifel.
The structure of the Moreno has a rough appearance with fine and irregular grooves in the sandy surface. The baking process is done in a gas-fired tunnel kiln under a slightly reducing atmosphere. By the homogeneous mixture of a precise proportion of manganese dioxide with grey-red baking loam, a light-brown brick is obtained. The colour shades of these hand-moulded facing bricks vary from dark-grey to black.
