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 new Swiss Diamond XDcoating contains 20% more diamonds than the previous HD coating.The new XD non-stick formula is produced using a new mixing andapplication system, developed specifically to obtain a morehomogeneous surface. This generates a more resistant layer,increasing durability by 40% compared to HD. In the laboratory testthe new XD coating exceeded 12,000 steps with coarse sandpaper. Theproperties of food release have also been improved compared to theprevious version.

A bit of history ... to understandbetter.
Swiss Diamond, a brand of excellence in the productionof high quality cookware. The company was founded in 1974 andmaintains its headquarters and production in Sierre, in the heart ofthe Swiss Alps.
The ever increasing demand for non-stick cookwareled the company to develop a revolutionary coating reinforced withreal diamond crystals in 2000. This innovative and patentedtechnology is recognized and awarded with the gold medal at theInventor Fair in Geneva.
In 2010, after four years of extensiveresearch and testing, Swiss Diamond's engineers have improved andfurther enhanced the coating to which they give a lifetime warrantyfor non-stick.
