Glaze fit

In pottery production, this is the term used to define the compatibility of the glaze and the clay within an acceptable range. Various problems such as glaze cracks, glaze flaking off the clay, or various cracks in the claybody (dunting) may occur if there is a mismatch between the glaze and the clay. When purchasing earthenware products, it is always wise to deal with an artist or a reputable dealer.  This is because they must have a better return policy or will stand behind their pieces with a warranty.
