IVV (Industria Vetraria Valdarnese) was founded in 1952 by a group of glassworkers in San Giovanni Valdarno, in the heart of Tuscany. For years, IVV has become one of Europe's leading glass and hand-made glass manufacturers, conducting in-depth research into materials, design, traditional craft techniques, and production controls. It creates a constantly evolving and innovating range of decorative and dining table objects. Transparency, brilliance, and a subtle tone are among the characteristics that distinguish high-quality glass from ordinary glass. These superior qualities are achieved to perfection at every stage, from the raw materials used, to the production techniques applied, to the skill of our glassworkers. It is a handmade product. Dishwasher safe at low temperatures.
