The Pyrolux Industry frypan is made from blue steel, which allows it to be used at higher temperatures than other frying pans, as well as preheating and cooking entirely without oil. The frypan is not coated, so it needs to be seasoned before and after each use to protect it from rusting. The seasoning will over time create a special layer, which is virtually non-stick as well as metal utensil safe. The pan is suitable for all heat sources, including induction. Handwash only. Blue steel, needs seasoning Withstands high temperatures and cooking without oil Nonstick and metal utensil safe once well seasoned Suitable for all cooktops, including induction handwash only
