Soup's on! Ideal for hot or cold liquids, these bowls are perfect for ladling out your favorite chicken noodle or for your daily cereal fix. Easily stackable. Named after the ancient town of Orleans in France's Loire Valley, these bowls are at once supremely durable (the glass is tempered) and wonderfully styled. Dishwasher and microwave safe. After inventing the glass tempering process in 1939, Duralex has spent the last 80-plus years making stylish, functional, and durable tempered glassware and tabletop pieces in La Chapelle-Saint-Mesmin, right in the heart of France. Much like their process, the quality of their glassware has remained unchanged over the years, and these traditions have helped them become a familiar name in households around the world.
