Do you ever wish you could dip a pot in the glaze bucket while holding on to the foot but there is no foot just an ungrippable slippery surface? These little suckers are $2.99 each at Harbor Freight. They are sold in the auto body dept for pulling out dents in sheet metal. With the flip of a lever, they will hold on to flat bottomed pots by vacuum so you can dip them and keep the foot clean. Also this way your glaze is thicker at the top of the pot and thinner at the bottom which is usually a good thing.
