No, the REN pans made of carbon steel are completely without artificial coatings of any kind , that is

• no non-stick coating / no PTFE / no PFAS, no ceramic coating, no enamel
• no coatings that could eventually peel or flake off and get into the food
• no potential risk of releasing pollutants in case of severe overheating

The dark surface typical of REN pans is the result of the reaction of nitrogen with the steel at high temperature, but it is not an artificial coating.

No, REN carbon steel pans do not require seasoning. However, we recommend conditioning them with oil according to the instructions before first use and briefly conditioning them with oil before each use to achieve the best possible frying and care properties.

No, absolutely not. REN carbon steel pans should only be washed by hand. Please do not leave them in the dishwater, and dry them thoroughly immediately after washing. Before storing, apply a few drops of oil to the inside with a lint-free cloth until no oil film is visible.

No. The wooden handle prevents oven use. If necessary, the handle can be unscrewed; however, it is not designed to be removable.

Yes, REN carbon steel pans work perfectly on induction cooktops . However, please note that overheating can occur very quickly, especially on induction cooktops, if you're not careful. Therefore, avoid using the highest power setting at all costs and never use the power/booster setting on the induction cooktop. Otherwise, the pan will stick and, in extreme cases, permanently warp the bottom of the pan. Always preheat the REN carbon steel pan at a low power setting before switching to a higher setting.

Yes, REN carbon steel pans are significantly lighter than cast iron pans. This is primarily because carbon steel sheet can be processed much thinner than cast iron.

Yes, the carbon steel body that comes into contact with the food is completely nickel-free, making it ideal for people who are allergic to nickel and have problems with stainless steel pans.

Thanks to the special oxide layer on the steel, REN pans are significantly more resistant to rust than conventional carbon steel pans, but they are not completely rust-proof. Therefore, it's important to treat them with care. This means no dishwasher cleaning, no leaving them in dishwater, and always dry them thoroughly.

Yoshikawa's Cook-Pal Ren carbon steel pans are exclusively and entirely manufactured in Japan.
