CREMA (Cream) Collection by Vietri (c). The combination of soothing cream with subtle terra cotta edges creates a statement of quiet elegance. - Handmade of terra cotta in Tuscany. - In the 1300's, peasants used rustic glazes on their hand-thrown pottery that separated during firing, exposing the terra cotta on the edges of the pieces. VIETRI reproduces these edges today using clear glazes. - Part of the Cucina Fresca Family of Dinnerware - Dishwasher safe. Charger, Dinner, Salad, Pasta Bowl, Cereal Bowl, Mug, Canape Plate, Espresso Cup and Saucer and Condiment Bowl are microwavable.
