As early as the Qin Dynasty in China, Meng Tian invented a pen made of rabbit hair and bamboo, which brought a writing tool revolution. At about the same time, the ancient Romans began to write with a thin brush or reed pole dipped in coarse ink, and called it "pencil", which means "pencil" in English. It was not until the 6th century that Europeans turned to quill pens. 1564, the British invented the graphite thin strip that marks Han. But this kind of thing is easy to get dirty and break. Later, someone wound the graphite rod with a string and used it. 176 1 year, Faber, a Bavarian craftsman and chemist, mixed graphite powder with sulfur, antimony and resin, cast it into a thin stick, and with proper coating, the prototype of modern pencils was formed.
18 12 years, Monroe of the United States made a pencil with a refill between two slats. In this way, modern pencils sprouted. The pencils we use now need 40 kinds of raw materials, and the varieties are diverse and the quality is constantly improving.
