Physical properties
Hardness: 5.5-6.5 (Mohs scale), Color: silver-grey, Luster: metallic, Crystal structure: face-centered cubic/body-centered cubic, Non-porous
Formation & geological history
Manufactured through the smelting and alloying of iron ore, chromite, and nickel. These minerals were formed in the Earth's crust billions of years ago through magmatic processes.
Uses & applications
Kitchenware, cutlery, and culinary tools due to its corrosion resistance and durability.
Geological facts
Stainless steel was first discovered in 1913 by Harry Brearley. It contains at least 10.5% chromium which forms a protective oxide layer that prevents rusting.
Field identification & locations
Identified by its distinctive reflective metallic surface and standard utensil shape. Found in household environments rather than natural geological outcrops.
