John Hesselberth is a retired chemical engineer who first had a 30-year career in industrial research. His pottery experience goes back about 25 years when he learned to throw after having built a kickwheel for his wife, Judy. Pottery remained a hobby until he retired from industry in 1996 and he has been building his pottery skills full time since then. He is a juried member of the Pennsylvania Guild of Craftsmen and he has authored articles for both Clay Times and Ceramics Monthly. Ron Roy has been a studio potter since 1963. His work is shown in many publications, including Robin Hopper's revision of Danial Rhodes' Clay and Glazes for the Potter and The Ceramic Spectrum, Richard Zakin's Ceramics-Ways of Creation, and Karen Ann Wood's Tableware in Clay.
Serious potters will welcome Hesselberth and Roy's approach to the complexities of formulating one's own glazes. They cover the durability of glazes, the leaching of unwanted chemicals into food or drink, the fading of colors, and more. --Library Journal
