IVV (Industria Vetraria Valdarnese) was born in 1952 by the hands of glass masters in San Giovanni Valdarno, in the heart of Tuscany. Over the years, IVV has become one of Europe's leading glass and hand-made glass manufacturers through its in-depth study of material science, design intricacies, traditional craft techniques, and precise production controls. Aiming for continuous innovation and change in decorative and tableware products, IVV creates stunning objects. Its transparency, brilliance, and light distinguish IVV glass from ordinary glass. These superior qualities are achieved to perfection at every stage, from the fine raw materials used, to modern production techniques, to the masterful touch of our skilled glass masters. Our hand-made products are dishwasher safe at low temperatures.
