A Vintage Prinknash Pottery Jug in a black lustre or "gunmetal" glaze. 

• The pottery was founded by Benedictine monks at Prinknash Abbey in Gloucestershire, England, in 1942. 
• Their work is typically red earthenware with a metallic, pewter-like glaze. 
• This specific jug has a bulbous shape and a pinched pouring lip. 
• The pottery continued production at the abbey until 1997.
