Every piece of Terrafirma is created with a signature process. The clay body is sourced from different parts of the United States – Tennessee, Misissippi, Ohio and Pennsylvania – to create our unique stoneware formula. The clay is extremely durable and vitrified, making it completely dishwasher safe. Patterns are painted through lace using liquid porcelain. The base of warm, natural stoneware juxtaposed with vibrantly colored and patterned porcelain surfaces achieves the casual yet sophisticated look that has become her signature in both dinnerware and accessories.
