Glazes from Natural Sources

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 somewhat localized, there is no part of this or any other country 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 is a practical book dealing with practical problems of prospecting, planning test programmes, making glazes and using them. The author deals with rock types and likely sources of supply, the making of test pieces and the use of blend systems and constructions. The emphasis is always on careful planning and control which ensures that results are repeatable. Brian Sutherland also clarifies the Seger system of glaze presentation for those who, like himself, have found it difficult to grasp and apply. He covers, and supplies, formulae for glazes for all temperatures - from raku to stoneware and porcelain and includes sample recipes.
