This Video will take you on a short journey through the manufacturing process of our bricks and pavers. From piles of dry clay, through the mixing process, the extrusion process, cutting, trimming, and through to firing. To produce a clay, bricks Natural raw Clay and Shales are first crushed and ground.
Brick-clay has a higher clay content and is more suited to pottery and tile making, due to its greater elasticity.

The drying process prepares the bricks for firing by extracting moisture from the soft "green" bricks. New and more efficient drying technologies such as the low-temperature dryer have reduced the drying period to one-third of the originally required time. ... After the drying process, clay roof tiles are either engobed (dip coated) or glazed ...
A brick is made by wetting clay, pressing it into a mould, which creates blocks. These blocks are fired in a kiln until they are hard. The process of making bricks generally consists of the following steps: Gathering, crushing, grinding, screening, and mixing the raw materials producing the brick.
Apr 12, 2017· Clay bricks of various kinds have been basic building materials for millennia. Do-it-yourselfers still like homemade bricks, whether for the satisfaction of doing it from scratch or to make uniquely designed bricks. Clay bricks require adding nonclay soils to prevent cracking, and fire brick requires a stabilizer to ...
The process of making clay bricks requires more than forming the clay into uniform rectangles. To make bricks strong enough to use for building, you must bake the clay. The baking process hardens the bricks so that they don't crack or crumble with use and turns soft clay into a hard, buildable material.

In medieval times, the clay for making bricks often was kneaded by workers with their bare feet. They clay was shaped into brick by pushing it into a wooden frame placed on a table, which was covered with sand or straw to prevent the clay from sticking. After excess clay was wiped off with a stick, the brick was removed from the frame.
All clay bricks when formed contain water, this is what makes the clay plastic enough to shape. This can range from 12% for extruded bricks, to above 25% in soft mud application. This water must be removed before the bricks can be fired. This process must be carefully
5. Firing the Bricks . Firing the Bricks. The final step in the brick making process was "cooking" the bricks in a kiln. The bricks had to be cooked to a high enough temperature to be "cured." Thousands of dry, raw bricks were stacked over a fire, and walls were built .
Clay brick making can be a rewarding experience, particularly if you plan to use your bricks to build a wall, or even a building. But for the novice who has never made bricks, it may take some detailed instructions, as well as information about materials, soils, and baking.
Clay bricks have been used for construction for thousands of years -- and while some advances have been made, and mechanization has made the process easier and faster, the essential technique for making bricks from clay has remained unchanged.
