The Le Creuset mug made of robust stoneware is the perfect size for tea, milk or coffee and the small version is ideal for espresso. Each mug is made by craftsmen using special clays that are fired at the highest temperatures. The result is a robust and stylish mug that can keep the drink warm for a long time. The glazed earthenware is scratch-resistant and temperature-resistant from -23°C to +260°C. The mugs can therefore be used in the oven and microwave as well as in the freezer. However, large temperature shocks should be avoided.
