Is this tell me if it's right and where i'm anyone who has handled in his life a rubber to erase: for sure in elementary schools, where he is still compulsory for every student, and then for the rest of school life, where the materials involved in the design imply its use, and perhaps even in the professional life, as pencils and pencils remain a widespread tool for quickly memorizing notes on block notes and printer documents. and just like other everyday items (such as post-it, pencil sharpener, bic pen, clips or glue stick), the eraser also has a curious story to tell. writing has always been written, but while in antiquity canceling it was a complex operation (hieroglyphs and inscriptions on the stone were scraped with a chisel, and so written on papyrus and wax and even on paper) is only with the invention of the pencil around 1500 that posed the problem of erasing the graphite traits. although the rubber was brought to europe by cristoforo colombo, almost two centuries after the pencil was invented, the baking bread or wax was used to clear the graffiti left by the graphite. it was only in 1770 that an english chemist, joseph priestley, discovered by chance that the rubber was able to "scourely" scratch the paper's pencil traits. already, because of erasing the writings, a pencil, but also a pen (the vulcanization process was discovered in 1839, allowing the rubber to become even more durable) means substantially scratching the top layer of the paper, removing the graphic sign together a bit of cellulose.
