Duralex glassware is made in France and includes drinking glasses, mixing bowls, storage containers, bakeware, dinnerware, and kids’ glassware. You can learn more about why I think glassware is the safest option in the kitchen in my blog post Lead Free Glassware Brands. For more information on Duralex, read below.
Duralex glassware is safe, which means it does not leach heavy metals such as lead, cadmium, arsenic, and aluminum. Keep in mind that ceramic dinnerware has risks of leaching lead and cadmium, especially if they are of bright colors and were made before the 1970s.
Duralex glass is made of a mixture of sand, soda ash, and limestone. That is a typical glass called soda-lime glass. In addition, Duralex uses technology to make the glass tempered. That means that it is supposed to be 2.5 times stronger than non-tempered soda-lime glass. Duralex glass products can withstand temperature extremes from -4°F to 212°F and is suitable for hot or cold liquids. And the OVENCHEF collection reinforced tempered glass resistant to a thermal shock of 200°C/392°F. Do not expose them to a sudden change of temperature of more than 130°C/392°F. If broken by strong shock, Duralex shatters into small pieces, reducing the risk of injury.
