An improved heat transfer release finish on cookware is formed by coating the cookware interior (sidewall and flat bottom) with a mixture of fluoropolymer and magnetic flakes and magnetically orienting said flakes to run in the thickness direction of the coating, followed by baking the coating. Advantageously, the coating mixture also contains compatibilizing polymer which enables the flakes to be so-oriented without creating minute fissures in the coating. |
