Dorket Head Brickworks Leaders: Keith Ambrose and Greg Kingston Wednesday 16th July 2014

摘要

Dorket Head Brickworks, near Arnold, is a part of Ibstock Brick Limited, and quarrying of clay started here in the 1860s. Current estimates suggest a future life in excess of 25 years for the available reserves, making around 180 years of brick making. It is one of several brickworks in the East Midlands, with many of the others being in Leicestershire. All of these pits work the Mercia Mudstone Group, which provides a good mix of clay, silt and sand. The quartz grains in the siltstones and sandstones are necessary to prevent excessive shrinking during firing. The mineral dolomite, also commonly present in the Mercia Mudstone, has the effect of producing paler bricks.
