Weathering steel is usually referred to by its trademark name COR-TEN (or simply Corten) and is known for its superior corrosion resistance. This is because the surface of the steel forms a protective oxide layer when exposed to the weather. In other words, the steel is allowed to rust in order to protect itself. This protective surface layer continues to regenerate over years of exposure. Corten a striking natural finish porcelain tile suitable for commercial and exterior applications is part of the Metallica collection from Tau Ceramica. Cortens look is inspired by corten steel, the predominant metal alloy in modern sculpture. This rectified edge tile is available in multiple sizes, and is designed to incorporate ceramics into the realm of creative architecture. The reactivity of the glaze along with the sophisticated glaze application method result in a tile that has huge natural variation making it truly unique. Corten is made using a porcelain body oxide tinted to co-ordinate with the glaze using Taus unique silica-alumina metal glaze technology.
