Right from his early days (60+ years ago), Ron was looking for a canvas on which he could apply a pottery glaze. Creating pottery with thicker or thinner rims would dictate which glaze would go where.
In his earliest days, information of raw materials was hard to come by, so potters often had to guess their way through recipes. Then calculating the percentages of different ingredients to assure that there is not too much or too little of either a flux (an oxide that lowers the melting temperature of refractory oxides), or a stabilizer (alumina) or a glass former (silica or borax) in a pottery glaze, never turned out the same two times in a row.
Ron wanted to visualize the inside of a ceramic glaze, so when he got his first computer, a new world opened for him. This experience of getting to know glaze making and to break the uncertainty and thumb sucking to obtain good and stable glazes became reality when Tony Hansen from Digital fire fame created the first Insight program.
It was with this program that Ron Roy became the glaze doctor, helping potters around the globe to fix glazing problems and to obtain sturdy clay and glazes.
Being a person that believe you have to give to receive, his contributions to Clayart, is (at age 86) to this day still unmeasurable.
The pottery book Mastering Cone 6 glazes, with co-author John Hesselberth is back on the market after it was first published in 2002. This book took the potters market by storm and almost every potter that worked at ^6 developed glazes from there; learning about the importance of stable and food safe glazes.
