Bake your family's traditional recipe of potatoes au gratin in the Lastra White Medium Oblong Au Gratin. The rustic shapes of Lastra were inspired by the overlapping wooden mold that was used for centuries to form Parmesan and other cheeses throughout Italy. Since 1983, Vietri has specialized exclusively in Italian handcrafted ceramics, stainless and pewter flatware, mouth blown glassware, lamps, urns and planters. Families of artisans with 3 or 4 generations of history create these special pieces using centuries-old techniques. The subtle color from a paintbrush and the curving stroke of the artist's hand are never repeated in quite the same way, making each piece truly unique.
