What Is Pencil Lead Made Of?We’re not in the habit of crushing dreams, but we have to break it to you: pencils do not contain lead. Instead, the pencil material is actually graphite. Plumbago pencil lead, to be exact. To get all geologist on you, plumbago is a naturally-occurring crystalline form of carbon arranged in a hexagonal structure. Fun fact: if graphite is under high enough pressures and temperatures, it turns into a diamond. Natural graphite is used in many ways, from batteries to brake linings to pencils, of course. |
For me, that is a huge win. I run a ton of community programs and teach afterschool science around the area, so the thought of it being 25x cheaper is huge.
