Thetford ware
From Wikipedia, the free encyclopedia

Thetford ware is a type of English medieval pottery mass-produced in Britain between the late ninth and mid twelfth centuries AD. Manufactured in Norfolk and Ipswich, Suffolk, the pottery has a hard, sandy fabric, and is generally grey in colour. Most vessel types include cooking pots, bowls, jars, pitchers, and lamps.
Thetford ware is a wheel-turned, mass-produced pottery having a hard, sandy fabric. Fabric colours vary from light to dark grey, and less frequently brownish-orange and buff. There are five types of forms manufactured: cooking pots, storage jars, bowls, pitchers and lamps. The cooking-pots were made in three sizes, with medium being the most commonly produced. The lamps were mostly a type of tall pedestal with hollow bases. Decoration was either unadorned or limited to applied-thumb strip decoration, several styles of rouletting, and incised bands. Rouletting is a process of carving patterns on pottery with a small toothed wheel. Rouletting decoration consisted of diamond and square shapes along with a mixture of diamonds and triangles.[1][2]
