Libbey Gibraltar Rocks Glass

DuraTuff is a specialized thermal treatment that strengthens the glass, making it significantly more resistant to mechanical and thermal shock. This helps the glassware withstand the rigors of a high-volume commercial environment, such as frequent stacking and dishwasher cycles.

While these are designed to meet the durability standards of professional bars and restaurants, they are an excellent choice for home use if you prefer heavy-duty, long-lasting glassware. Keep in mind that they come in a bulk case of 36, which is ideal for large households or frequent entertainers.

Yes, the Gibraltar design is specifically engineered for stackability. Their faceted shape and sturdy base allow them to nest securely, which is a key space-saving feature for both professional bars and home kitchens.

These glasses have a total capacity of 10 ounces. This size is standard for a rocks glass, making it well-suited for a single pour of whiskey or bourbon over ice, as well as various classic cocktails.

Yes, they are fully dishwasher safe. The DuraTuff process ensures they maintain their clarity and structural integrity even after repeated cycles in a commercial or home dishwasher.
