Making a covered jar, on the potter's wheel, represents two basic challenges. One is to throw the form, so they're stable in their drying and bisque firing and glaze firing condition and the second one, is taking a correct measurement of the jar and the lid, for the jar, itself. We will be using calipers to achieve that goal. It's very important that the clay be the same moisture content, at the beginning of the operation, so it shrinks at the same rate in the drying stage and the firing stage. There are a lot of different covered jars. Today we'll be using a flange type covered jar lid. Also, at some point, we'll be demonstrating trimming the jar, after it has dried to the leather hard consistency. This involves using trim tools and it is taking off excess clay, off from the top of the jar itself. In some instances, the right time to trim it is critical, in that, if it's too soft, the piece will deform and if it's too hard, the trimming will not come away successfully.
