Clay blocks (sometimes called clay block brick) being laid with an adhesive rather than mortar. Bricks are made in a similar way to mud-bricks except without the fibrous binder such as straw and are fired ("burned" in a brick clamp or kiln) after they have air-dried to permanently harden them. Kiln fired clay bricks are a ceramic material ...
Clay pit in Britain. A clay pit is a quarry or mine for the extraction of clay, which is generally used for manufacturing pottery, bricks or Portland cement. Quarries where clay is mined to make bricks are sometimes called brick pits. [1] A brickyard or brickworks is often located alongside a clay pit to reduce the transport costs of the raw ...
[2] Brick from the Clay Cross Company's brickworks. At the time Clay Cross was a small village, but production of coal and minerals created a surge in the population. Nearly 400 houses were built for the workers (tunnel navvies initially and then miners) and their families, and by 1846 the population around Clay Cross approached 1500.
The compressive strength of bricks produced in the United States ranges from about 7 to 103 MPa (1,000 to 15,000 lbf/in 2), varying according to the use to which the brick are to be put. In England clay bricks can have strengths of up to 100 MPa, although a common house brick is likely to show a range of 20–40 MPa.
A stock or stock board is an iron-faced block of wood fixed to the surface of the moulder's bench. The brick mould fits over the stock; the brick maker fills the mould with prepared clay and cuts it off with a wire level with the top of the mould, before turning out the 'green' brick onto a wooden board called a pallet for drying and firing.

A mining simulator is a type of simulation used for entertainment as well as in training purposes for mining companies. These simulators replicate elements of real-world mining operations on surrounding screens displaying three-dimensional imagery , motion platforms , and scale models of typical and atypical mining environments and machinery.
