Frequently Asked Questions
Everything you need to know about our legendary tempered glassware.
What makes Duralex glass different from regular glass?
Duralex glassware is made from tempered glass, which is 2.5 times stronger than ordinary glass. It is resistant to thermal shock and is designed to withstand sudden temperature changes from -4°F to 212°F.
Is Duralex glassware microwave and dishwasher safe?
Yes, all Duralex products are 100% dishwasher and microwave safe. Our tempered glass is non-porous and will not absorb liquids, colors, or flavors over time.
What happens if a Duralex glass breaks?
If struck with extreme force, Duralex tempered glass is designed to shatter into small, blunt pieces rather than sharp shards, significantly reducing the risk of injury.
How long does shipping take for my order?
Standard shipping typically takes 3-7 business days within the continental United States. You will receive a tracking number via email as soon as your order leaves our warehouse.
What is your return policy for damaged items?
We offer a 30-day return policy. If your glassware arrives damaged or defective, please contact our support team with a photo of the item, and we will send a replacement at no extra cost.
Are Duralex products lead and cadmium free?
