Fact 94: What are pencils made of?


Now, as anyone who has ever been to the (in my opinion the amazing) Derwent Pencil Museum (in Keswick UK) will proudly tell you, they are not made of lead (toxic) despite the fact that some pencils are labeled as lead pencils they are in fact made and have aways been made from a slightly,  similar looking thing called, graphite (nontoxic) some pencils also have more or less clay in order to change the gradient tone or the pencil the more clay that is added to the graphite stronger and smoother and means the graphite will not brake or snap in side the wooden caseing and the the clay having more clay added to the graphite makes the pencil create a lighter mark on the paper. The less clay makes the pencil less the les strong the pencil is ( more breakable) however the mark is darker.
