Lead in Pencils: Safety Information and Facts. You are here: Home / Lead in Pencils: Safety Information and Facts. As mentioned on our The Unleaded Pencil page there is no lead in the writing core of a âleadâ pencil. The core is made of non-toxic graphite and does not contain lead. As a result of increased concern for the safety of different consumer products such as toys or art products from China, we often receive inquiries regarding the potential for exposure to lead in pencils.
Today pencils are numbered and/or lettered to tell us how hard the lead is. The higher the number, the harder the lead, and the lighter the markings. However, it wasn't always this way. The earliest pencils were made simply from filling a wood shaft with raw graphite. The hardness of the graphite would differ depending on the quality of the graphite, thus it was different depending on where the pencil was made. The current style of making pencils was developed in 1794 by Nicolas-Jacques Cont (1755-1805).
