The common name “pencil lead” is due to an historic association with the stylus made of lead in ancient Roman times.Did You Know? This may come as a shock to some people but lead pencils do not contain any lead. Never did. The “lead” actually is a mixture of graphite and clay; the more graphite, the softer and darker the point.Because they were cheaper, even if they were toxic. But, you certainly wouldn’t want to suck on a “lead” pencil if it really had lead in it. In fact, lead pencils became extinct only in the early 20th century.
