Dunoon bone china mugs are hand made in England and are made of the finest bone china. Dunoon Ceramics is a family-owned company based in Staffordshire that still leads the market in the production of high-quality bone china. Each coffee mug is made of clays sourced from Cornwall in southwest England. This clay offers the best translucency, whiteness and durability. Dunoon mugs are not machine made; rather they are made using the "slip casting" method whereby liquid clay is poured into forms. This process creates a superior mug that is light to hold, fine to the touch and offers the best experience when drinking coffee or tea.
