Heirol Blacksteel is a professional black carbon steel pan where thoughtful design and reliable quality take your cooking to another level. The specially treated black carbon steel provides excellent non-stick properties and better corrosion resistance than regular carbon steel pans. The Blacksteel pans are treated with nitride, after which they are heated in the oven with nitrogen dioxide, allowing the black oxide layer to form. The pans are also pre-seasoned with vegetable oil, further enhancing their corrosion resistance. The pans' non-stick properties only improve over time with use. The 3mm thick pan doesn't even bend under the toughest use. The pans are designed to withstand high temperatures and are suitable for all stovetops, ovens, grills, and even open fire. The long handle is riveted for ultimate durability. The pan heats up extremely quickly and has excellent and energy-efficient heat conduction capability. With proper use and care, you can make your Blacksteel pan a lifelong companion for your most delicious cooking adventures! Psst! The appearance of the pan will change after the first use. This is normal and does not affect the cooking quality. The patina will improve the cooking results with each use over time.
