The "Quality One" series is classically elegant. The traditional bulbous shape is combined with modern accents. The signal red dots on the side handles are a visual reference to the unique Cool+ Technology, which is only available from WMF. The glass lid is for all those who like to look into the pots when cooking. The Quality One range has everything you expect from good cookware: the lid made of heat-resistant quality glass has a steam opening for controlled evaporation during cooking. The TransTherm all-stove base distributes the heat evenly and retains it for a long time. It is suitable for all hob types. The Cromargan: 18/10 stainless steel material is easy to clean and indestructible. Cool+ effectively reduces heat transfer from the pot to the handle. This makes Cool+ the world's first patent-pending handle technology that exceeds the requirements of the DIN EN 12983-1 standard.
