After a lot of research and trial and error, I finally have the right grinding system set up to finish off the bottom of these pots, thanks to Tim Scull of Canton Clayworks (a master of crystalline glazes among other things), who gave me step-by-step instructions. Because this type of glaze is a “runner”, I fired them with a pedestal/glaze catcher attached to the bottom. Afterwards, the pedestal is knocked off, leaving sharp and rough edges of glaze that need to be ground down and polished. Tim recommended an expanding drum with three different grit sanding belts attached to a lapidary motor, and sure enough, it worked like a charm. One of these beauties went to a dear friend, to hold her father’s ashes. I’ve had a lot of requests for memorial urns lately, and I find that I really like making them. It is an honor to make something that is so sensitive and meaningful to other people’s lives.
