Pencil manufacturing. The top sequence shows the old method that required pieces of graphite to be cut to size; the lower sequence is the new, current method using rods of graphite and clay.

Graphite is the allotropes of carbon. It is black and soft.

As we all know carbon is a black element and the graphite is the softest allotropes of carbon. If you try. To break a pencil you will find the middle black part (graphite).

Easily breaks it makes impression on light surface it imparts carbon to the surface of paper therefore graphite is used in pencil.

The central lead of pencil is made of graphite which is black, soft and hence makes markable impressions on the paper.

Its a carbon compound and the graphite is very soft that's why it will easily broken.

Its a derivative of diamond and used in pencil and very soft.

graphite and pencil is having same features.

Lead is used because it is soft and easy to sharp.

If pencil writes black due to graphite then which element is used in color pencils.

Aside from being the material in your lead pencils, graphite is of tremendous value as an industrial material. It is used to make the brushes for electric motors and generators, and it has wide use as an electrode in a number of applications, primarily batteries.

Graphite has been, is, and will continue to be critically important to maintaining and advancing modern civilization. And this because it is in things we use every day, and because it is used in industrial processes that provide the foundation we build our society on.
