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 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
