What is "graphite"?
Graphite is a soft, black material made up of carbon atoms arranged in layers that can slide over each other. This structure makes it highly conductive, allowing electricity to pass through easily. Graphite is commonly used in pencils because it leaves a mark on paper, providing a range of shades depending on its hardness. It is also used as a lubricant in machinery and industrial settings because of its smooth, slippery qualities, which reduces friction.
