Le Creuset manufactures heat-resistant glass caps in different sizes to match the Toughened non-stick series and all the Le Creuset pots and pans. With the transparent glass lid, you can keep an eye on the food without having to lift the lid, which can lower the temperature and affect the boil. The lid helps to preserve the food's juiciness and taste, and also makes it possible to use the pan for poaching, brushing and stewing. Can be used in the oven up to 220 ° C. Dishwasher safe. Le Creuset leaves a two-year warranty on all glass caps.
