Chemical processes have been present in the lives of people from the dawn of history until the present time. Initially, these presses were not under our control, for instance, the fermentation of fruit juice, the rotting of meat and fish, and the burning of wood. Later on, we learned to control chemical process and to use them to prepare a variety of different products such as food, metals, ceramics and leather. In t
