Pencil lead is composed of two primary minerals: graphite and clay. Graphite is a soft mineral, while clay is harder.

The hardness and softness of the pencil lead depend on the ratio of these two components. A higher proportion of graphite results in a softer lead, while more clay leads to a harder one.
