The secret of solidity

THE TEMPERING PROCESS IS OUR TRADEMARK

Since 1945, Duralex has pioneered tempered glass technology, a process in which we are specialists. Our plant in La Chapelle-Saint-Mesmin was the first in the world to produce tableware in tempered glass.

Thanks to our ongoing investment and commitment to quality, Duralex has achieved a level of excellence that has made the brand successful worldwide. Our company is indisputably recognized as the leader in tempered glass.

WHAT IS TEMPERED GLASS?

What makes Duralex glass so resistant is the tempering process. This consists in cooling the entire glass product by ventilation, after it has been heated to a temperature of around 700°C. This treatment creates controlled stresses in the glass that enhance most of its physical qualities: resistance to mechanical stress and thermal shock (sudden temperature change). This makes Duralex glass at least 2.5 times more resistant to mechanical stress than annealed glass. It can withstand a thermal shock of at least 130°C.

WHY IS TEMPERING SO IMPORTANT?

The Duralex tempering process improves resistance to mechanical stress and thermal shock. It offers safety, convenience and durability, extending product life.

Tempered glass is safer, stronger and therefore more sustainable than annealed glass. Tempering ensures greater strength for the glass as a whole, as well as making it safer in the event of breakage (it shatters completely into small pieces).

Our commitment to quality and our regular checks guarantee stable hardening.
