How did the eraser appear?

In the last issue we told the guys about how pencils appeared. The one who draws with them, and especially with a simple pencil, knows: you can’t do without an eraser. It is especially necessary for those kids who are just learning to draw.

So when did eraser appear? Judging by her modern composition, relatively recently, but people have been drawing for thousands of years. But it turns out that the eraser was born... before a simple pencil! The eraser dates back to the 1700s, and the first graphite pencil was patented (that is, its authorship was recorded) in 1802.

Of course, eraser used to look completely different. To erase inscriptions made with charcoal or a bread pencil, they used... bread crumb! But from 1736 to 1746, one astronomer, surveyor and traveler Charles Marie de la Condamine was in South America. There he saw how the Indians extracted rubber from plants. The scientist brought samples of this substance to Europe. For a long time they didn’t know what to do with it, until one day another scientist, Jean-Hyacinthe de Magellan, accidentally tried to erase what he had written in pencil with it. So “Indian rubber” began to be used everywhere. However, natural rubber is sticky and deteriorates quickly when separated from plants. In 1844, Charles Goodyear figured out how to make rubber artificial so that it would not age. This is how a technological process appeared under the complex name “vulcanization”. Later, another American inventor, Hyman Lipman, was the first to come up with the idea of ​​combining a pencil and an eraser.

How does an eraser work? It turns out that in the process of rubbing the rubber band on the paper, electrostatic voltage appears. Very small graphite particles, separating from the paper, stick to the eraser particles. In addition, the eraser polishes the paper, making it smooth. A dirty piece of eraser crumbles together with adhered pencil particles - thus the eraser also cleans itself.

What is plasticine made from?

Before the invention of plasticine, people sculpted from clay. Professional sculptors still use it today. However, plasticine is convenient for kids - there is no need to fuss with water to soften the clay. You can always knead it and mold something again, but clay dries out, and in order to mold it again, you need to place it in water. In addition, plasticine can be bright colors, which cannot but attract the attention of children. What is plasticine made from? It consists of crushed and purified clay powder, only wax, animal fats and substances are added there that prevent it from drying out. The very word “plasticine” comes from the Italian word plastilina, and it comes from the ancient Greek plastos, which means “molded, plastic.” Two people claimed authorship for the invention of plasticine: the German pharmacist Franz Kolb in 1880 and the English art school teacher William Harbutt in 1899. Moreover, both patents for inventions represented a non-drying material that could be used repeatedly. At first there was plasticine gray, like clay, but then, seeing how children were happily modeling from it, Villas Harbutt began adding pigments (dyes) of plant origin to it.

Who came up with the line?

A ruler is a very important item. Kids in kindergarten they learn to draw straight lines along it, schoolchildren use it to build figures and measure their length and width, and for drafting engineers and architects it is generally a working tool.

Where did the line come from? During excavations ancient city Pompeii archaeologists found carefully planed planks. Scientists decided that ancient people drew straight lines on them. Later, in the Middle Ages, monks were considered the most literate people; they used thin plates of hard metal– lead.

People used all sorts of objects to draw straight lines, even iron rods! Remember yourself, parents: when there is no ruler at hand, we draw... using the cover of another notebook, a plastic card, even mobile phone! This was the case in ancient times.

But the modern line begins with French Revolution 1789. Then scientists were given task: invent new system measures Everything old was exchanged for new: the calendar, the names of the months, money. The French Delambre and Mechain first calculated the length of the earth's meridian - 40 thousand kilometers. From this measurement we took the forty-millionth part and got the meter. Later, the meter was divided into centimeters, and the centimeter into millimeters.

At first, meter-sized rulers were used only in academies. Later, students began to use them. Only in early XIX centuries, rulers appeared in ordinary schools and became much smaller in size.
