Pencils began to be used in the mid-16th century after a large deposit of graphite was discovered in Borrowdale, England, and wooden-cased pencils and the modern graphite‑clay process were developed later (standardized by Conté around 1795). Graphite is a crystalline form of carbon with layered sheets that slide past each other, producing the dark, lubricating particles used as the "lead" in pencils; it is mixed with clay and binders to adjust properties. An HB pencil is a medium‑grade pencil (H = hard, B = black) that balances hardness and darkness, making it the common general‑purpose writing/drawing grade. Increasing the H number (e.g., H to 2H to 4H) makes the core harder and lighter because there is more clay relative to graphite, so marks become finer, paler, and less smudgy.
