In the making of firebrick, fire clay is fired in the kiln until it is partly vitrified.For special purposes, the brick may also be glazed. There are two standard sizes of fire brick: 9 in × 4 + 1 ⁄ 2 in × 3 in (229 mm × 114 mm × 76 mm) and 9 in × 4 + 1 ⁄ 2 in × 2 + 1 ⁄ 2 in (229 mm × 114 mm × 64 mm). [2]
The Hoffmann kiln is a series of batch process kilns. Hoffmann kilns are the most common kiln used in production of bricks and some other ceramic products. Patented by German Friedrich Hoffmann for brickmaking in 1858, it was later used for lime-burning, and was known as the Hoffmann continuous kiln.
The Hoffmann Continuous Kiln was the first move towards mass production. It was a series of downdraught kilns, connected in a circle or in a long rectangle. Each kiln had an access channel to the next so as soon as the one kiln was fully firing process, the waste heat would begin to fire the next. The fires would thus burn around in sequence.
The other major kiln type is the Bull's Trench Kiln (BTK), based on a design developed by British engineer W. Bull in the late 19th century. An oval or circular trench is dug, 6–9 metres (20–30 ft) wide, 2–2.5 metres (6 ft 7 in – 8 ft 2 in) deep, and 100–150 metres (330–490 ft) in circumference.
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 ...
