Medieval (Late 11th to mid 12th century)
These jars are in the same tradition as the squared rimmed cooking pots found in fabrics 57, 57.1 and 58. They seem to be amongst the first products of the Worcester kilns in the late 11th century. They were not produced in great numbers and were almost certainly not produced later than the mid to late 12th century.
