Ron Roy Workshop

Understanding Clay & Glaze Chemistry - 2006

Ron Roy will share his deep expertise in matters of clay and glaze chemistry. Participants will review the Seger unity formula in detail as it relates to glaze calculation. Ron will demonstrate the use of INSIGHT and GlazeMaster software programs for understanding and adjusting glaze recipes. Participants should bring examples, problems, projects and questions for this weekend of consultation with one of the top experts in the field. All participants will receive a copy of Ron's valuable 30 page Glaze Workshop Book.

Specific topics will include subjects like adjusting glaze recipes to cure crazing, shivering and crawling; adjusting glazes for use at different firing temperatures; making line blends to test adjustments; how to raise or lower the shrinkage and maturation temperatures of clay bodies; firing cycles for bisque and glazes; and reformulating for substitution of materials in clay and glazes. Audience participation and requests will shape the flow of discussion to a great degree.

Ron co-authored the authoritative text on ^6 glazes.

Class size 18.

Ron Roy Bio

After finishing his formal Education in ceramics at the Ontario College of Art in 1963 Ron established his studio in Scarborough. From this time until 1971 he was a studio potter and part time educator in ceramics. During this period he participated in many shows, won numerous awards, executed several architectural commissions, laid the foundation for Rodaco Clay, and served as a volunteer in two major craft organizations. He set up the studio, developed the curriculum and taught at Centennial College continuing education department from 1967 to 1985.

1971 marked the incorporation of Rodaco Clay in response to the community's need for well designed and quality processed clay. In June 1981 Rodaco was taken over by his partner and Ron returned to the creative life of a studio potter and the task of re-establishing himself in the more demanding discipline of porcelain. After a few group shows he entered the "Perfect Setting" dinnerware show which opened at Government House in Ottawa and won the special Award for Contemporary Design.

Ron is currently concentrating on technical writing, consulting, leading workshops, and his dilatometry experiments.
