Glassmaking has been an Italian art form for centuries. Since around 1200 AD, the Veneto region of Northern Italy around Venice and especially the island of Murano has been the world's most important glassmaking center. Generations of knowledge paired with individual innovations make Italian glass the pinnacle of the art. Vietri Imperial Glassware continues this tradition of excellence. It is mouth-blown in Veneto from Pyrex glass. Pyrex is lightweight but durable and allows the artisans to create extaordinary detail. The lines are elegant and classic yet with a touch of singular whimsey. Add some real impact to your table. Imperial glassware is dishwasher safe on a low energy setting with a mild, non-abrasive detergent that does not contain chlorine, alcohol or perfume.
