Damascus steel, renowned for its distinctive patterns of wavy lines and marbled textures, has held a prestigious position in metallurgy and craftsmanship for centuries. Originating from ancient forging techniques, this material is not only celebrated for its strength and sharpness but also for its ability to exhibit a wide spectrum of colors through various treatments. Coloring Damascus Steel Through Heat Treatment. The process of coloring Damascus steel begins with its core composition, a fusion of iron and steel forged through layers. The coloration stems from heat treatment, a method that alters both its appearance and properties. By heating the steel, a thin oxide layer forms on the surface, reflecting light to produce an array of colors. The temperature and duration of heat exposure are pivotal in determining the thickness and hue of this oxide layer. Blue: Achieved by heating the steel to about 290°C (554°F) for a short period, then cooling it rapidly. Purple: Obtained by heating to roughly 350°C (662°F) for a longer time before a rapid cool down. Blade Length : 3 inches. Overall Length : 7 inches. Blade Material : Blued Damascus Steel.
