From its invention to the present day, the pencil has become a witness to the progress of human civilization. This article will take you to explore the scientific principles and artistic charm behind the pencil. II. The Science of Pencils: 1. Composition of Pencils: Pencils are mainly composed of leads, bars, and erasers. The lead is a mixture of graphite and clay, which is burned at high temperatures to form a writing surface with excellent performance. The bar is made of wood or plastic material, providing a comfortable grip for users. The eraser is used to erase mistakes. 2. Manufacturing Process of Pencils: The manufacturing process of pencils seems simple but actually involves scientific principles. Firstly, graphite and clay are mixed in a certain proportion, then placed in a mold and burned at high temperatures to form the lead. Then the lead is inserted into the bar, and finally, an eraser is added. At this point, a complete pencil is born.
