IVV (Industria Vetraria Valdarnese) was founded in 1952 by glassmakers in San Giovanni Valdarno, in the heart of Tuscany. Over time, IVV has become one of Europe's leading glass and hand-made glass manufacturers. Through research into materials, design, traditional craft techniques, and process controls, we continually innovate our decorative and tableware creations, transforming each object into a timeless work of art. The transparency, brilliance, and resonance of glass are the qualities that distinguish it from ordinary materials. These superior qualities are achieved to perfection at every stage, from the raw materials used, to the fine techniques applied, to the skill of the glassmakers. It is handmade.
