Each product has been crafted from glass which is heated to ~700°C then suddenly cooled by cold air ventilation. The result is a glass that is more than twice as strong as standard glass, with exceptional resistance to shocks both thermal and mechanical. Basically, it means that glassware has been built to cater perfectly for the rigours of even the most demanding modern home or kitchen, for as long as that home or kitchen needs it to. These glasses represent the true connoisseur's choice, with a design tailor-made to bringing the finest flavours and aromas. Set Size: 12
