The prepared clay mixture is transported by conveyer belts to the souring house. At this stage of preparation, a homogenization of the clay moisture takes place and a further clay digestion by bacteria happens. Moulding . The next step is the moulding of the clay to get the final shape of the un-burnt product, the so-called "green brick".
