The Hoffman continuously fired brick kiln was invented by Friedrick Hoffman () of Germany in the late 1850s. Before then brick making was a small industry, which used singlechamber kilns, which had to be fired, then cooled and emptied before the next load could be processed.
The wood was set alight from an opening at the bottom, from which the burnt lime was extracted. It was used for building purposes such as mortar and pointing for brick laying and masonry. The kiln was worked continuously till 1889, and spasmodically for another three decades. The local coal was low grade so high grade coal had to be carted in.
The Hoffmann kiln was a horizontal ring kiln originally developed for brick making but soon applied to the lime industry which it revolutionised by enabling the large scale, continuous, production of lime. In 1868 work commenced building such a kiln at Meal Bank and the works were operated under the name of the Ingleborough Patent Lime Works.
