Story: Rock, limestone and clay

Coal and clay

Coal and clay

In this road cutting south of Charleston on the West Coast, a 2-metre-thick deposit of clay lies beneath a layer of coal. In the past this clay was dug out and used to produce ceramic toilets. Clay and coal are often found together. It is a fortunate mix, as many brickworks used the coal to light the kilns that fired the clay.
