They sit right in the birthplace of the Industrial Revolution, and have been inspired by the 18th and 19th centuries' Shropshire Iron masters, especially Abraham Darby. Netherton Foundry has been designing cooking products for over three decades. Over the years, they have become more and more interested in the provenance of the materials they use. Their objective is to build quality products made from materials principally sourced in Shropshire and its neighbouring counties. They are committed to reducing our impact on this fragile planet by building products that will last, from materials they trust.
