The authors of this site, John Hesselberth and Ron Roy, have a strong belief that the glazes we potters put on our pots should be both durable in use and attractive. For too many years potters who have written glaze books and articles in magazines have paid attention only to the aesthetics of the glaze and not to suitability for use. The result has been a lot of glazes in the open literature that, while attractive, have one or more faults that make their use on functional pottery highly questionable. We now have two products to address this issue.

The first is the book "Mastering Cone 6 Glazes", first published in 2002 and now in its 6th printing with over 18,000 copies sold. In it we demonstrate, beyond doubt, that glazes fired in an electric kiln to cone 6 can be both attractive and durable. And we show you how to make sure yours are. 

Please note that the printed copies are now "Out of Print" and there are no currect plans to print more. As noted below "Mastering Cone 6 Glazes" is also available as an ebook on Apple's iPad, iPad mini, iPhone, and iPod Touch. Buy it from within the iBook app on one of those devices.

The second product is the glaze calculation program "GlazeMaster™" which serves not only as a great database for glaze recipes, but also as a tool to help potters design new glazes and analyze or adjust existing ones.





Both of these products are described in detail on this site and we hope you will enjoy learning about them.
