What is a charcoal pen

Charcoal pencils are common tools for painting and sketching.The main raw material of charcoal pencils is charcoal powder.Charcoal is produced by incomplete combustion of wood.Some charcoal pencils carry the ochre brown tone of charcoal and are generally black.Charcoal pencils feature rough matte surfaces suitable for creating dry textured lines with strong stroke intensity,and diverse texture effects can be formed through rubbing and wiping,endowing charcoal pencils with outstanding expressive power.However,charcoal adheres firmly to paper and is hard to erase with erasers,leaving little room for revisions.Its rough surface may damage paper if excessive drawing force is applied,yet proper control can turn this feature into a unique expressive technique.Charcoal drawing tools include charcoal sticks,compressed charcoal sticks,charcoal pencils,carbon pencils and pastel sticks.Charcoal delivers non-reflective rich tones with stronger visual impact than regular pencils and accelerates drawing speed.

Artworks created with charcoal can be coated,smudged and erased,as well as rendered with lines or block surfaces to form abundant tonal variations.Therefore,charcoal pencils serve as standard practice tools for traditional plaster sketches and are mainly applied in sketch creation.
