In the 1800s, Aldridge became an industrial town with coal mines and lime kilns. The coal and clay in the area prompted many to set up collieries and brickworks. Aldridge clay is especially useful in the manufacture of blue bricks. The 1881 census shows that the mines and brickworks were major employers. Because the coal and clay beneath the eastern side of Aldridge (towards Stonnall) is located much deeper under the surface, extraction of this coal and clay would not have been economically viable. As a result, farms continued to dominate the eastern part, though a sand quarry was set up and still remains on Birch Lane.
