This unique brick deserves compliments
The facade bricks (non-perforated) have five sand covered sides and one side with possible oblong groove. The structure looks rugged with fine and irregular grooves in the sandy surface. The baking process takes place in a gas-heated tunnel oven under slightly reduced atmosphere.
By the homogeneous mixture of manganese dioxide with grey-red baking Löss loam, Nelissen Steenfabrieken obtains a red-brown brick. The brick has a surface with finegrained sand and colours that vary from orange-brown to purple-brown brick with blue shades. The colours shown are a near reflection of reality.
