Non-stick diamond coating applied by nanotechnology, no PFOA.Swiss Made quality 100% manufactured in Switzerland. Very highthermal conductivity thanks to the fusion of thick aluminum and thediamond coating. High-pressure aluminum die-casting, non-deformablethermal base with plasma anti-corrosion treatment of the internalsurface. Resistant handles, knobs and glass in the oven up to 260 °C.
Lids (if any) in tempered glass, shock-resistant edge in steeland adjustable valve for steam vent.

The ever increasing demand for non-stick cookware led thecompany to develop a revolutionary coating reinforced with realdiamond crystals in 2000. This innovative and patented technology isrecognized and awarded with the gold medal at the Inventor Fair inGeneva.
