Libbey Gibraltar Glass

DuraTuff is a specialized thermal process that strengthens the glass, making it significantly more resistant to both thermal shock—like sudden temperature changes—and mechanical shock, such as accidental bumps or drops in a busy kitchen.

Yes, the glass is designed to handle hot beverages like espresso. The DuraTuff treatment specifically helps the glass withstand the thermal stress of hot liquids.

The glass features a thick sham (the base) and a balanced, paneled design, which provides a low center of gravity. This makes it very stable and less likely to tip over on crowded trays or tabletops.

While the paneled design offers some grip, these glasses are not specifically engineered for stacking. We recommend storing them side-by-side on shelves to prevent chipping or getting them stuck together.

This model has a 4.5 oz. capacity, which is the standard size for a double espresso or a small rocks pour.
