Flint is a hard, sedimentary cryptocrystalline rock that is commonly gray in color but can also occur in shades of white, yellow, orange, red, brown, black, or green. The color of flint is determined by the minerals it contains, such as quartz, chert, or calcite. Flint is typically composed of microcrystalline grains of silica, which give it its characteristic hardness and fracture pattern. Flint is commonly used in the production of tools and weapons due to its sharp edges and durability, and it has been a valuable resource for humans throughout history.
