From the manufacturer: Supremo Collection: Wine Ambassador: The stemglasses of the Supremo range have been designed by Luigi’s designers. The stemglasses are produced in machine blown SON.hyx crystal glass, and with a new process making them lighter and thinner while maintaining their strength. The bowl shapes are innovative and elegant and have unique sensorial perceptions: Emphasizing the wine’s aromas during their development in the bowl while lessening the alcoholic element. In this way the wine’s aromas and flavors develop pleasantly in the bowl. After 10 minutes, all wines contained in a Supremo wine glass lose the alcoholic aroma elements while the wine’s specific aromatic characteristics are enhanced to the fullest. The stemglass design is suitable for specific wine varietals. How It Works?: The chimney balances the wine aromas with a low alcoholic content The conical shape condenses the alcoholic vapors so only the wine aromas will develop The smooth connection between the conical and convex shape avoids the breakage of aromatic molecules The Convex surface balance wine oxidation and retaining the most delicate aromas Epicure at the base of the bowl, shows the real wine color reflection Permanent ultra break-resistant stem is applied SON.hyx Technology: Crystal Glass Par Excellence Developed and registered by Luigi. A high-tech blown lead-free crystal glass that does not contain and heavy metals. This glass present outstanding chemical, optical and mechanical properties. Mechanical resistance is significantly enhanced thanks to appropriate production processes. Glassware made of crystal glass have an improved resistance to mechanical shocks. In fact, laboratory tests have demonstrated the improvements. Due to these improved processes the surface of the glass does not have any weak points thus reducing the glass fragility and improving its mechanical resistance. Ultra Clear, Totally Transparent and Sparkling: Strong High Resistance to Breakage: +37.5% Resistance of the rim +105% Resistance to impact test +98% Resistance to twisting of stems Resistant to Washing Cycles: No alteration in transparency and brilliance over 4,000 industrial cycles Sound amplifier Lead and other heavy metal free Produced with low CO2 emission level Titanium Reinforced Technology: Permanent anti-abrasion treatment on the glass’ stems. It is a process developed and carried by the Luigi Research and Development Department by applying Nanotechnologies directly on the glass’ stems. This process hardens the glass surface increasing its resistance to abrasions, which are responsible for the fragility of the stems during daily usage. It increases the stems’ resistance to breakages by 140%, permanently.Luig ‘s Titanium reinforced treatment is the most reliable, as it: Guarantees the stems’ resistance to breakages even after multiple industrial washing cycles Glass sparkle and transparency is maintained Avoids any glass discoloration.
