What rock is often used to make chalkboards?
Essentially, yes.Pencils contain graphite (pencil lead), which is a type of carbonic rock.Graphite is used because it forms mollecular layers which easily slide over eachother, allowing the material to easily transfer to the intended medium.The misconception that pencils contain lead comes from the use of the word alongside pencil in reference to the graphite column.
