Schott Zwiesel
German glass innovators Schott Zwiesel make crystal drinking glasses that are thin and elegant - but astonishingly strong. Their patented Tritan crystal glass is lead-free, instead using titanium oxide to create an exceptionally durable crystal. Unlike most crystal glasses, they’re dishwasher safe - and what’s more, they’re tempered at weak points for extra strength. Their impressive break resistance makes them a favourite with high-end hotels and restaurants - as well as the chronically accident-prone.
