A hand-moulded brick with a touch of red and purple

Rosina is a hand-moulded brick with a red surface. The colour shades vary from orange-red,bright red to purple. Nelissen Brickworks obtains these nuances by mixing Löss clay with sawdust on one hand and with reddish brown, grainy, moist sand with blue shades on the other hand and this in a certain proportion. The brick is made from Löss from Limburg, extracted from the plateau of Kesselt in the Meuse valley and revalued with raw materials from the Volcanic Eifel. The baking process is done in a gas-fired tunnel kiln under a slightly reducing atmosphere.

The non-perforated brick is covered with sand at five sides and provided with a possible oblong sloping groove on one flat side (frog, group 1). The brick is characterized by a rough appearance with fine and irregular grooves in the sandy surface. Rosina is part of the Passion range of Nelissen Brickworks.
