American Toby Jug Museum 

Cooper toby jug produced by Artone Pottery of Burslem, England, circa 1980. A cooper is a craftsman who produces wooden casks, barrels, vats, buckets, tubs, troughs, and other similar containers from timber staves that were usually heated or steamed to make them pliable. Journeymen coopers also traditionally made wooden implements, such as rakes and wooden-bladed shovels. In addition to wood, other materials, such as iron, were used in the manufacturing process.
