Duralex: known for our nearly unbreakable glassware and timeless style made from just fire and sand. Since 1945, we have pioneered tempered glass technology. 100% of our products are made in France. The tempering process is our trademark, which makes our glassware so strong and durable. Glass is heated to around 1292 degrees Fahrenheit, then suddenly cooled by cold air ventilation. Tempering improves the strength of the glass, making it highly resistant to breakage and suitable for hot and cold liquids. Our glass is at least 2.5 times stronger than non-tempered glass. Constant quality control guarantees that all of the products are of the highest quality.
