Most pencil cores are made of graphite mixed with a clay binder, leaving gray marks or black that can be easily removed. Graphite pencil used both for writing and drawing, and the result is durable: although writing can usually be removed with an eraser, resistant to moisture and chemicals, ultraviolet radiation and natural aging. Other types of pencil core are less widely used. Most pencil cores are made of graphite mixed with a clay binder, leaving gray marks or black that can be easily removed.
