| Abstract: | This article presents an overview of the Hemerdon China Clay Works, 6 miles north-east of Plymouth (Devon), active from c.1860 to 1942. Based on research commissioned in advance of an extension to Headon West Quarry, it describes the development of the clay works and the methods of clay extraction and processing. Archaeological survey recorded a broad range of structures, features, earthworks and artefacts. They included the remains of an engine house of c.1907, two large masonry bases (probably associated with the flat rod system that transferred power from the engine) and a rocker beam. The article also describes a group of mica drags and settling tanks built c.1907. Combining this evidence with that gleaned from documentary sources, notably the large-scale Ordnance Survey mapping, an exceptionally detailed narrative has been constructed of the work's development through time. It has a relevance beyond the particular, and will help the future interpretation and management of the china clay extraction sites that are so characteristic of the region. |
