Libbey – Paneled
A basic and well-known tumbler range which is covered by the Libbey Duratuff ®-treatment. These Durable glasses suitable for soft drinks, juices, smoothies or milkshakes. Paneled tumblers will fit any operation.
DuraTuff® – Libbey’s DuraTuff® treatment is a super strengthening thermal after-process for “pressed” tumblers and stemware.
The DuraTuff® process is only performed on the upper third of the glass, which increases its resistance to thermal and mechanical shock. By treating this upper portion at a lower temperature than tempering, you put less stress on the glass. This has a positive effect on how the glass breaks and also improves its overall durability.
