“The Whats of Devon and Dorset?” I hear some say; the more learned will already know that without ball clay we wouldn’t have plates, loos, basins, spark plugs, rubber hoses etc. - this is useful stuff and the best deposits of it worldwide are near Wareham in Dorset and Bovey Tracey and Petrockstowe in Devon where it is both mined and ‘quarried’. This excellent value book describes the background to this industry, how the clay is extracted and transported, and what it is used for. 52 pages. 61 illustrations. Paperback.
