Stamford ware is a type of lead-glazed earthenware, one of the earliest forms of glazed ceramics manufactured in England.
The most popular forms were jugs, spouted pitchers, and small bowls.
Distribution of Stamford ware has been used to map trade routes of the period.
This depended on many factors including glaze composition, iron content and whether fired in reduced or oxidised conditions.
