Grease pencil or wax pencil can be used to write on glass. Actually the pencil was invented by Nicholas Jacques Conte in 1795. He grounded graphite and mixed it with many types of clays and pressed the mixture into sticks and finished them in a kiln. The word “Pencil” comes from the latin word “pencillus” which means “little tail”. Before pencil was invented people used to write with a quill pen where the tail of the quill is used for writing. Pencils made with more clay produced a harder pencil whereas a pencil made with more graphite produced softer pencil. A pencil is made up of wood and graphite. But later years over 350 flavors of pencils with 72 colored varieties have been introduced. One of them is a Grease pencil which allows you to mark on glass.
