Flint is a type of sedimentary rock known for its hardness and sharp edges. It has been used by humans for thousands of years, primarily for tool-making and fire-starting.
- Appearance: Flint is usually dark gray, black, or brown and often has a smooth, glassy surface with a conchoidal fracture pattern, which means it breaks with smooth, curved surfaces. It can also come in shades of green and red.
- Formation: Flint forms from the accumulation of silica, often in the form of chalcedony or quartz, within sedimentary rocks like limestone or chalk. It typically develops in nodules or layers.
- Uses: Historically, flint was crucial for making tools and weapons, such as arrowheads and scrapers, due to its ability to be knapped into sharp edges. It is also used for starting fires and has applications in construction and landscaping.
- Metaphysical Properties: In metaphysical practices, flint is believed to be a grounding and protective stone. It is thought to help with clarity of thought, enhance focus, and offer protection against negative energies.
