From the late 18th century, Usk became well known for the high quality of its japanware, a process of decorating metals by applying a lacquer to tinplate. The process, known as Pontypool japan, was first developed in the west by Thomas Allgood of nearby Pontypool and was taken on in Usk in 1763 by his grandsons Thomas and Edward Allgood. Products from Usk included tin trays, jardinières, and coal boxes. However output declined with changing fashions in the 19th century, and the last Usk japanware was produced in 1860 on the site of what is now Bunning's builders' merchants.
