Any real education in ceramics must involve, from the outset, an appreciation of the source materials—the rocks around us. While good, throwable clay may be a regional commodity, there is no part of the world that will not yield potential glaze materials in abundance. Potters therefore need to know how to exploit the special properties of local rocks quickly, reliably, and methodically. This new revised and updated version of Brian Sutherland's classic book on making glazes from natural sources explains how to locate glaze material and construct, test, and use the glazes created.Glazes from Natural Sources discusses rock types and other likely sources of supply, the making of test pieces, and the use of blend systems and constructions.
