Here is a large platter with a decorative rim. I demonstrated how to make this in the studio for students. They got to see how I formed it and made the special rim. Next I showed how to make the handles and a week or so later I glazed it during a class dedicated to glazing. I made this particular piece from a clay body that i normally do not use, so my glazes might look or behave a little differently. Out of the kiln..... beautiful color and shape. but I immediately heard some very disturbing pings. Clay and Glaze need to "fit" together, and I knew immediately that this clay did NOT like my glaze! It sheared in two pieces from the stress between the clay and the glaze. Complicated chemistry , but using my normal clay body corrects the problem. Watch the video.......
Here is another piece that was used as a glaze demo in class last week. 2 colors working in concert.
