Mount Vernon, George and Martha Washington's family estate, licensed this lovely design. The Washingtons had a deep affinity for stoneware and creamware and used it extensively. Salt -glazed fragments excavated from the grounds were replicated in great detail for this pattern. The most well known style of the period, English Staffordshire stoneware was popular by 1765. Our design is made of pure white hard porcelain and is guaranteed stain-proof, microwavable and dishwasher safe.
