Glass is a natural mineral. Natural glass is grey and hard to look through. Man-made glass was first produced in Egypt 5000 years ago. It was used for decorations because it had a green or blue colour. The secret of clear glass was found in Europe only in the 13th century. At the same time, craftsmen learned to produce lenses to look at small objects or to be used by people who had problems with their eyes. This is how the first glasses appeared. Glass dishes and mirrors became popular later with the rise of technology. In Russia, the first glass factory was built in Moscow region in 1654.

People have always wanted to learn and share information. At different times they I used different methods to exchange news. They made fires and beat drums to signal important events. Later, they invented letters which were carried by special people called runners. They had to cover long distances to deliver information. The use of horses and birds made the delivery quicker. The state post in Russia appeared in the 17th century. It was rather slow but quite reliable. In 1851, the post started to use the railway. Since then the speed of information exchange has been growing constantly.
