Sketches can be made in any drawing medium. The term is most often applied to graphic work executed in a dry medium such as silverpoint, graphite, pencil, charcoal or pastel. But it may also apply to drawings executed in pen and ink, ballpoint pen, water colour and oil paint. The latter two are generally referred to as "water colour sketches" and "oil sketches". A sculptor might model three-dimensional sketches in clay, plasticine or wax.

Classifications and Types of Pencils for Sketching...
• Graphite pencils:- standard everyday pencils with a core of clay and graphite of clay and graphite and a casing of wood. They have many levels of darkness, which are achieved with different ratios of graphite and clay, and variety of uses.
• Solid graphite pencils:- (or woodless pencils) similar to standard graphite pencils but without wood casing. They are used for drawing, allow for covering of large areas and also have many levels of darkness.
• Charcoal pencils:- pencils shaped like sticks and made of charcoal and used in art. They are black (and darker that graphite pencils) but there are also sepia toned and white.
• Grease pencils:- pencil made of wax core and, most often, with paper casing. Some rarer grease pencils have wooden casing. They can write on almost every surface and it rarely scratches the surface it is used on.
• Carbon pencils:- pencils made of a mixture of clay and lamp black (a black pigment). Their darkness changes with mixing with charcoal or graphite. They are still darker than pencils but smoother than charcoal pencils.
