Course Description
Are you tired of the studio glazes? Tired of the same old same old in magazines, books and what you see at pottery sales? Then this is the course for you. This is an intensive course using a base recipe. We will select substations for glaze materials, to develop 5 bases, blend colourants, opacifiers and as well as variegation effects. You will work in groups to complete all the glaze work. All you need is a basic knowledge of mixing glazes, ceramic materials and application methods. It is best to use a white/cream coloured clay body; however, the clay body you currently use is the best. The following topics will be covered;
