Pots, pans, and other tools by celebrity chefs are now 10 percent of the U.S. cookware market, according to the Cookware Manufacturer’s Association. But after their five minutes of fame, will these products last in your kitchen?

Chef André Soltner, former owner of Lutèce restaurant in Manhattan, and John Doherty, executive chef at the Waldorf-Astoria, recently tested cookware by Rachel Ray and other Food Network darlings. The results? Disheartening.

The silicone handle of a Rachel Ray frying pan caught fire during testing; Emeril Lagasse’s lightweight pans could be bent out of shape by hand; and the nonstick coating on Todd English’s cookware chipped easily. The chefs also reported that Ray and English’s cookware scorched badly during cooking.

Marcus Samuelsson’s stainless steel line, which Regal Ware produced, was “the only one that would make it in a commercial kitchen,” according to Doherty.
