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 five granite beehive-shaped charcoal smelting kilns that have survived in Frisco were created by the Frisco Mining and Smelting Company under the supervision of Benjamin Y.

As it burnt through, lime was extracted from the bottom of the kiln, through the draw hole. Further layers of stone and fuel were added to the top ...
The beehive-shaped kilns are each about 20 feet (6.1 m) tall and 20 feet (6.1 m) in diameter.
