We have used copper since the dawn of civilization. In fact, ten thousand years ago, humans used it for multiple purposes. Perhaps what is most surprising is that, by being infinitely reusable, it is likely that some objects that we use today come from a long chain of recycling, for example, pipes of ancient Egypt or the utensils that the Romans produced with ore brought from Cyprus. In a world in which the preservation of the environment has become a priority, this feature will be increasingly appreciated, especially in the developed countries.
