I found this 18th century jug and others like it in a book I got from Colonial Williamsburg.  Salt-Glazed Stoneware In Early America  My work is not salt glazed, but I have attempted to make the jugs as close to the old pieces as possible.   Because of variations in raw materials, and atmospheric conditions when firing, the jugs could vary in looks from those shown.

This is the quart size.  These jugs are made to be used and enjoyed.
