DuraTuff Design

Thanks to a special thermal after-process applied to the top portion of the glass, you can rest assured that it has exceptional durability. This DuraTuff treatment is designed to increase the glass's resistance to mechanical and thermal shock while also making it safer to use. When a normal glass breaks, it typically shatters into tiny pieces, but DuraTuff glasses will break into larger pieces, shortening cleanup and making them a much safer alternative for everyone at your establishment.

Libbey DuraTuff

Libbey DuraTuff glassware provides you with safe and sophisticated glasses! Using an innovative strengthening and heat-treating after-process, DuraTuff glasses incorporate more mechanical strength and thermal shock resistance than regular glasses.

Let's face it--glassware breaks. How a glass breaks is more important. The way a glass breaks in your bar or restaurant can make a big difference in operations and profitability. Libbey's DuraTuff treatment is a super-strengthening, heat-treating after-process that increases the durability of the glass. Libbey produces some of the safest and most durable glassware in the world and here's why. This demonstration shows how fully tempered glassware breaks. Tempered glass explodes, sending small jagged pieces of glass up to ten feet (3 meters), causing disruption in your bar or restaurant. These glass pieces can cause harm to customers and can contaminate food and drinks. Let's not forget the extensive downtime to clean up the broken glass! A Libbey DuraTuff glass will not explode. When a Libbey DuraTuff glass fails, the glass typically breaks into large pieces that are less likely to risk injury or contaminate food and drinks. They provide easy clean up, too. The Libbey DuraTuff process also increases both mechanical strength and thermal shock resistance, the two biggest factors that affect glassware performance in pubs, bars, and restaurants. You can count on Libbey for a safer, more durable, and more profitable glass!

    glasses Glass rocks Happy durable quality cocktails bar great Nice
    I have a few much older 9oz Libbey glasses and love the look and the size. These are the same style, but are not shaped the same: a bit taller and not as wide, but the same volume. Similar look, so I'm happy. They seem sturdy.
    These liquor glasses are absolutely breath taking. The quality is superb. I did not expect the quality to be as good as it was considering the price.
    This item was perfect for what I needed! It was just as described. Smooth transaction, great product. Great service. No problems. Thank you! I recommend this product
    I’ve worked in or around a bar for over twelve years now and these are the glasses that always outlive any others. Stackable, breathable, durable.
    The Gibraltar rocks Glass is a classic way to serve signature cocktails and top shelf liquors. It pairs well with the Gibraltar espresso / rocks glass.
    Nice, thick glass. These rocks glasses are high quality and can withstand daily use in a busy bar. Very comfortable to hold as well. Happy customer!
    These are a great, sturdy glass for mixed drinks. We store them in crates in our store, but they stack well for events or for moving.
    i was very happy with how durable these 9 oz rocks glasses were. they have really held up well in all of our bars. i am very impressed.
    We put these glasses to work especially during happy hour and they hold up very well to use and many cleanings. I like that even after high use the glass is still clear and not foggy.
    These rocks glasses do the job. Perfect for cocktails and they look nice. Pretty durable also. They do not chip or break easily either. We endorse.
    I would recommend this glass as a large rocks glass for any bar. We have been using Libby barware for over a decade and are very happy
    These are the perfect rocks glass. The price and quality is what we really compared on glasses, and these were the winners! They are a very nice glass.
    We use these for our regular cocktail glasses these are very thick solid g lasses and are very durable and usually last a long time under normal use
