The silver grey colored brick
Bretagna is a hand-moulded facing brick of Nelissen Brickworks, made from Löss from Limburg. The brick is extracted from the plateau of Kesselt in the Meuse valley and is revalued with raw materials from the Volcanic Eifel. The homogeneous mixture of a precise proportion of manganese dioxide with loam in combination with fine white sand obtained a silver grey stone. Bretagna is sanded on five sides with fine silver sand and provided with a possible oblong sloping groove on one flat side (frog, group 1).
Bretagna is part of the Grigio range of Nelissen Brickworks.
