Lastra - The rustic yet chic shapes of Lastra were inspired by the overlapping wooden mold that was used for centuries to form Parmesan and other cheeses throughout Italy. The Artistry - Signor Stefano Roselli is the master molder for a ceramics cooperative located in a small town seven miles outside of Florence, and he is the creator behind this collection. VIETRI has worked with Stefano and factory owner Franco Ammannati for close to 15 years, creating and bringing to market dinnerware collections, vases, urns, and other home decor products.
