A combination of Campine and Old Quaternary clays are mixed and kneaded together to obtain the desired elasticity. Minerals are added before the clay is crushed and prepared. The extruder then compresses the clay through pressure and suction into a long rectangular shape. At this point, various liquid clay engobes and other natural colourants such as calcium and manganese are added to create a wide range of colours and tones, not usually achievable in clay brick production. The desired brick module is then cut using a die. The wet bricks are dried for 4 days, then fired in an automated tunnel kiln reaching temperatures of 1250°c. The result is a rustic edged, contemporary and multi tonal facing brick.
