SOFT MUD TUMBLED
Clay taken from a quarry or river is mixed with other raw materials such as sand, lava, lime, iron and chromium oxides. The clay is put through various processes to remove any unwanted aggregates or metals. It is then kneaded with steam and water before being thrown by machine into a “Deboer” press. The moulds are lined with a heavy sand which holds back some of the clay when tipped from the mould. This gives the brick a simulated handmade texture. The shaped bricks are then dried before being fired in a tunnel kiln at temperatures ranging from 1070°c – 1250°c. Once the bricks have been fired, they are tumbled and cemented with different colour pigments. The result is a rustic, through coloured, stock brick with a reclaimed appearance.
