Metals occupy the three quarters of Dmitri Mendeleev’s periodic table of elements. Gold and silver were the first metals discovered by people more than 8 000 years ago.
Thanks to their mysterious shine they were used as jewelry from the very beginning. Steel and iron were discovered 7 000 years ago. These metals were suitable for making a fishhook, household items and weapons.

The Celts were the first who tried to get steel in the 4th century BC.
