Product Details

Why can graphite be used as the core of pencils?

First, it’s black; second, it has a soft texture—indeed, it’s one of the softest minerals. When you lightly run it across paper, it leaves a visible mark. If you examine the pencil mark under a magnifying glass, you’ll see that it’s composed of tiny, fine particles of graphite. The hardness or softness of a mineral is an important indicator for identifying its type.
