Engineered Superiority: A Technical Breakdown of Borosilicate Glass
Understanding the material is key to appreciating its value. Unlike common soda-lime glass, our high borosilicate glass is defined by a unique molecular structure rich in boron trioxide. This results in measurable, superior performance:

• Low Thermal Expansion Coefficient (≈3.3 x 10⁻⁶ /K): This technical attribute grants exceptional resistance to thermal shock. You can safely transition it from a cold rinse to a warm dishwasher without risk of stress fractures.

• Optical Clarity & Chemical Inertness: It offers brilliant transparency (high light transmission) without the cloudiness or metallic oxides found in inferior glass. It will not impart any odor or taste, ensuring the wine’s integrity.
