The origin of the eraser:
In p>177, the British scientist Joseph Priestley said, "I saw a substance that is very suitable for erasing pencil handwriting." At that time, the whole of Europe used rubber particles cut into small cubes to wipe away handwriting. This substance is called an eraser.
Edward Naime, another British engineer, is regarded as the inventor of the eraser, also in 177. Before that, people used bread crumbs to wipe away handwriting. Naime said that he accidentally picked up a piece of rubber as bread crumbs once, but found that it worked well, so he began to produce and sell erasers.
the initial eraser is not convenient, because raw rubber is easy to rot. Until 1839, the inventor Charles? Goodyear? It is found that vulcanization can improve the quality of rubber and the eraser becomes reliable.
In p>1858, a Lippmann from Philadelphia, USA, obtained a patent for embedding an eraser in the tail of a pencil. However, the patent of this pencil with an eraser was later revoked because it was judged as "only embedding two existing things together instead of a new product".
Types of erasers:
The first type, brown, pink and black drawing erasers, are basically rubber erasers. Soft, opaque to strong light sources.
The second rubber commonly used for sketching is the plastic rubber (soft rubber), which, as its name implies, can freely shape its shape and is also the softest one in the rubber family. Not suitable for daily writing.
