Attention Students: Know Your Charcoal and Graphite

Graphite is a mineral, a crystalline allotropic form of carbon. In the 16th century a large deposit of graphite was discovered in Cumbria, England. Initially it was thought to be a form of lead and was called plumbago (lead ore). Today the graphite core of pencils is still referred to as "lead."

The Unleaded Pencil – Pencils.com

These composite graphite-clay “leads” allowed for more efficient use of graphite and revolutionized the pencil industry. Not only did the formula reduce costs, but by adjusting the ratio of clay and graphite powder, the changing hardness allowed more control of the lightness and darkness of the graphite mark left on the paper.

Pencil - Wikipedia

Graphite sticks were initially wrapped in string or sheepskin for stability. England would enjoy a monopoly on the production of pencils until a method of reconstituting the graphite powder was found in 1662 in Italy. However, the distinctively square English pencils continued to be made with sticks cut from natural graphite into the 1860s.
