Grafit

The hand-moulded facing brick with grey surface

The Grafit is a hand-moulded facing brick of Nelissen Brickworks. By the homogeneous mixture of a precise proportion of manganese dioxide with Löss loam, a dark graphite grey colour is obtained. The Grafit is made from Löss from Limburg, extracted from the plateau of Kesselt in the Meuse valley. This facing brick is revalued with raw materials from the Volcanic Eifel.

The non-perforated facing brick from the Obscuro range is sanded on five sides and provided with an oblong sloping groove on one flat side. The structure of Lava 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.
