This is a new, revised and updated version of Brian Sutherland's classic book on making glazes from natural sources.
It is essentially a practical book that deals with locating your own glaze materials, and how to construct, test and use the glazes you create. Rock types and likely sources of supply, making test pieces, the use of blend systems and the Seger system are all fully discussed.
The emphasis is always on careful planning and control which ensures results are repeatable. This makes the science behind making glazes from natural sources both understandable and feasible.
