Aluminum is the best heat conductor for pots and pans. (Only copper conducts heat better but is significantly more expensive). SCANPAN Classic and Professional use 200 tons of pressure to squeeze the liquid aluminum alloy into the pan shape, eliminating any air and other inclusions. This results in a perfectly flat pan base, perfect heat distribution, no hot spots and superior heat retention. The thickness of the SCANPAN pan base has scientifically been determined to provide fast and even heating. SCANPAN Cookware is especially suited for ceramic and glass top ranges. And it works with electric and gas cook tops, of course, as well. And the pan base thickness combined with the ceramic titanium surface allows for browning, searing and deglazing!
