Fissler Intensa Series 9 Piece Cookware Set The CookStar base, made of extra thick alumininum core and high quality 18/10 stainless steel, ensures tha the base will never separate, warp, or develop hot spots, even on induction stoves. The ThermoStar temperature inducator is built into the lid. The only one of it's kind, the indicator changes color to tell you exactly what is happening inside your pot. This reduces cooking time and reduces energy consumption. The pot and lid system are designed so the lid will integrate into the handle allowing for easier, mess-free cooking. With the lid up condensation drips back into the pot, and your hands are free for other tasks. The patented pouring function built into each pot enable hot water or juices to be poured out with the lid on. A turn of the lid at 90 degrees seals the lid for gentle vitamin-friendly cooking. All Intensa pots feature drip free rims. Intensa is designed to maximize precious space in the kitchen. The slightly conical shape of the pans allows for all pieces of the same diameter to be stacked inside each other without wedging or scratching.
