In ancient times, our ancestors and even our grandmothers followed the practice of storing water in containers made of copper. Their aim was probably to safeguard drinking water and to create a natural purification process. Storing water in a copper vessel creates a natural purification process. It can kill all the microorganisms, decays, fungi, algae and bacteria, present in the water that could be harmful to the body and make the water perfectly fit for drinking. In addition, water stored in a copper vessel, preferably overnight or at least for four hours, acquires a certain quality from the copper.
