The Libbey 1637HT is a 20 oz commercial-grade mixing glass from the Restaurant Basics series, engineered for demanding bar and foodservice environments. Its signature DuraTuff heat-treating process strengthens the glass against thermal and mechanical shock, particularly in the upper portion where impact is most common. If breakage does occur, the treatment prevents dangerous shattering into small shards, reducing contamination risk and simplifying cleanup. With a top diameter of 3-3/4 inches and a sturdy base, this clear glass handles cocktails, beer, iced tea, and soda with equal versatility. It is an ideal choice for high-volume establishments that need reliable, long-lasting glassware.
