We all once used colored pencils. Someone is only in drawing lessons at school, and someone is using them so far. And after opening the box, many people are interested in the question: why do we need a white pencil?
Modern pencils exist about 200 years. Graphite was found somewhere 5 centuries ago in English mines. There is an opinion that it is from then on that graphite pencils have been manufactured. One German family in 1760 began to make such tools with graphite powder. However, this process was not very successful. French scientist Conte in 1795 made pencils made not only from graphite, but also from certain types of clay, which he pre-fired in the oven. This technology is still popular. A simple drawing pencil is made of graphite and leaves a dark trail behind it. For its production graphite powder is mixed with water and clay. The hardness of the product is determined by the amount of clay. The more it is - it is softer, the smaller - firmer. The test paste, which is formed from this mixture, is passed through the press, after which ropes are formed, which are straightened, cut to the desired size and fired in the oven. Then cedar or pine blanks are cut along, make a special ditch for the lead, and then glue together with it. The resulting plates are cut and polished. To date, about 300 varieties of pencils are produced. They are different in hardness and color. Today there are 72 colors of these products. With their help they put inscriptions on glass, cloth, plastic and even film. Some of them are used in construction to leave a trace that will persist for a long period of time.
