Humber ware

Humber ware is a type of Medieval ceramic produced in North Yorkshire, England in the late 13th to early 16th Centuries AD.

[4] Forms include jugs of various sizes, cooking pots and (in the later phases of the industry) urinals and bung-hole cisterns.

[5] Several Humber ware sherds have a white encrusted deposit on the interior surface, which has been found to derive from urine.

[3] Decoration is usually limited to bands of horizontal grooving on the shoulders or neck, with occasional patterns of wavy combing, rouletting, or stamping.

[2] One of the best known products of the Humber kilns are the small drinking jugs, which replaces wooden bowls used in earlier times.
