Slate pencils in India(more specifically southern India) are made from a type of sedimentary rock known as Shale, which is composed of mud that is a mixture of clay minerals (kaolinite,montmorillonite and illite) and small quantities of other minerals especially quartz and calcite. The ratio of clay to the other minerals gives the shale its colour. Shale from which slate pencils are made, are light gray in colour.
