Among the metals, copper is special. It is closest to gold with its alchemical characteristics and its healing effects. Only a few decades ago the healing properties of copper were used for growing plants by placing a copper coin overnight into the watering can. Nowadays this method works less effectively since the percentage of copper in coins has been lowered due to financial reasons. Overnight, the properties of copper were transferred into the water and this had a strengthening effect on the plants. Likewise, it is still custom in certain countries to keep drinking water overnight in a copper vessel.
