By the late 18th century, an ancestor of the modern pencil was constructed by inserting a rod of natural graphite into a hollow cylinder of wood. Pencil rods produced from mixtures of graphite and clays, true prototypes of the modern graphite pencil, were introduced in 1795. This improvement allowed for better control and encouraged wider use.

18世纪晚期出现了现代铅笔的始祖，由一段石墨芯嵌入中空的圆柱形木头制成。笔芯由石墨和黏土的混合物制成，现代石墨铅笔的真正原型在1795年才出现。这一改进使铅笔比较好控制而为更多人使用。
