After my story about cast-iron cookware [“Cast-iron cookware: Good for you and lasts forever,” Food & Flavor, July 17], I received several queries from readers asking if you can use cast-iron skillets on glass or smooth-topped stoves. I asked Mark Kelly, the public relations and advertising director for Lodge Manufacturing Co., who said, "Yes, you can use on glass-topped stoves. Simply place it straight down and do not move around on the surface. When finished, lift it straight up."
His answer is below. I'll add the caveat: Just to be careful so you don't damage your stove.
Thanks for all the nice comments and questions.
