                                    DRAWING CAN BE FINISHED WORKS OF ART, or preparatory studies for painting and other visual arts. they can be made using a wide variety of drawing instruments such as pencils, graphite sticks, chalks, charcoal, pens and inks, and silver wires. the most common drawing instrument is the graphite pencil. a graphite pencil consists of thin rod of graphite mixed with clay, encased in wood.

      charcoal is one of the oldest drawing instruments. it is produced by firing twigs of willow, vine, or other woods at high temperatures in airtight containers. erasers can be used to rub out marks made by drawing materials such as graphite pencils or charcoal, or to achieve a particular effect such as smudging. fixative is often applied using a mouth diffuser or aerosol spray fixative to prevent smudging once a drawing is finished.

silver wire across specially prepared paper permanent and cannot be erased. in time the silver lines oxidize and turn brown.
