The stackable glass bowls that survive the drop, the freezer, and the microwave. Named for the clear-running Lys River that threads through France and Belgium, Duralex Lys bowls are the everyday workhorses of the kitchen: impact- and chip-resistant tempered glass that nests thanks to collared rims, so a whole set tucks into one cupboard stack. They move straight from freezer to microwave, hold hot or cold, and clean up in the dishwasher. Duralex tempered glass is 2.5 times stronger than ordinary glass for increased impact and chip resistance Suitable for hot and cold liquids (-4°F to 266°F) and highly resistant to thermal shock Nonporous; won't absorb liquids Moves directly from freezer to microwave; dishwasher safe If broken by a strong shock, shatters into small pieces to reduce the risk of injury Collared rims let the bowls nest to save cupboard space Made in France since 1939 Dimensions: 4 oz (3.5"), 10 oz (4.75" x 2"), 1 qt (6.75" x 2.75"), 2.5 qt (9" x 3.75"), 3.5 qt (10.25" x 4")
