Jug, c.1500, Sieburg, Germany, unglazed stoneware, Victoria and Albert Museum.
From the V&A:
This funnel-necked drinking-jug is made from Siegburg clay. This type of clay proved ideal for making tough wine and beer mugs for export throughout Europe. Potters produced such pieces by throwing them quickly on a kick-wheel and then firing them to a high temperature using wood. The result was a hardwearing white stoneware.
Iran, 14th century.
