Founded in 1892, Libbey has become synonymous with quality glassware and tabletop supplies throughout the world. This is due to Libbey’s DuraTuff technology. DuraTuff is a strengthening, heat-treating process that makes glassware more resistant to both thermal and mechanical shock. When glass does break, it ensures it is in large chunks instead of exploding in small pieces, protecting your customers and saving valuable time cleaning up.
