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 kilns represent the only remaining brickyard in Washington, D.C., and one of the few extant examples of the rounded "beehive" kiln style. The structures are constructed of red common brick, lined with heat-resistant firebrick and capped with arched, brick roofs. [1] The complex also contained eight exhaust stacks.
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 updraught kiln, also called a Scotch Kiln, was rectangular and open-topped with fire holes along the bottom; it was a permanent cowl. It was filled with bricks and it allowed the hot gases to rise amongst them. The downdraught kiln was circular and about 15 ft in diameter; the hot gases rose but were deflected back down onto the bricks ...
The height and the diameter of the kiln can vary, and consequently, so did the number of fire mouths. The kiln is entered through a clammin which was designed to be big enough to let in a placer carrying a saggar. The kilns are enclosed in a brick hovel which can be free standing or be part of the workshop. [5] Kiln floor, the well-hole and bags
