The set (including wok, frying pan, milk pot, and soup pot) combines cutting-edge innovative technologies with traditional craftsmanship. It not only meets consumers’ functional demands for durability, non-stick performance, and light weight, but also enhances the joy of cooking through thoughtful design details, making it an ideal choice for the modern kitchen.
99% of the set is made from ultra-pure iron imported from Japan, using top-grade ore with over 64% iron content, refined with traditional smelting methods and modern vacuum refining technology, to produce iron with an exceptional purity of 99.6%. This high-purity iron ensures fast, even heating that brings out rich, authentic Chinese flavors. OTN Titanium-Nitride Infusion Technology perfectly combines light weight with exceptional durability. In furnaces at 900 degrees Celsius, an ultra-high-pressure co-infusion process injects pure oxygen and nitrogen into the iron-based lattice, forming a 50 μm iron-nitride composite layer. This significantly boosts rust resistance by 90% and increases hardness to three times that of conventional iron cookware, enabling it to withstand frequent scraping from metal spatulas. The result is cookware that is both robust and surprisingly light, allowing users to easily lift it with one hand and making cooking more convenient and enjoyable.
Traditional hand forging gives the cookware its distinctive “scale” texture, which is not only visually artistic but also functionally effective. The raised and recessed scale pattern, in combination with nano-scale pores, reduces the surface area in contact with food by 40%, delivering physical non-stick performance. Despite its durability, the cookware weighs only half of conventional cast iron cookware, making cleaning quick and easy. In terms of special finishing, a three-layer deep oil baking process with each layer baked at a constant 260 degrees Celsius infuses oil molecules into the iron’s micro-pores, forming a dense, non-stick, and rust-resistant oil film. This eliminates the need for traditional “seasoning” procedures, so the cookware is ready to use straight out of the box.
