WHITEFORD'S UNIQUE COATING SYSTEM. Whiteford's Excalibur coating is considered to be the world's toughest and most durable non-stick coating. This coating system is made by arc-spraying a proprietary stainless steel alloy onto the article, becoming a part of it after cooling down and hardening. The resulting matrix of "peaks" and "valleys" is then impregnated with premium nonstick coatings, forming a durable nonstick coating system. * Bio-compatible, containing no harmful chemicals. * Lightweight relative to other metals * Cooking with minimal oil usage. * Transfer heat fast with uniformly distributed heating. * Easy to clean.
