This special handmade carafe in a polished finish with a stopper is made of pure copper (the stopper can also be used as a cup).
Note: the cup stopper of this carafe fits loosely and therefore does not seal watertight. The carafe is not intended to be carried around.
Ayurveda has advocated the benefits of drinking water from copper vessels since ancient times. Ayurveda states that when you store water in a copper bottle or cup for 8-10 hours, it has a balancing effect on the three bio-energies (doshas) that circulate through the human body (Vata: air element, Pitta: fire element, and Kapha: water element). Additionally, water in copper vessels turns into naturally alkaline water, which helps to keep your body's pH level balanced.
Due to natural oxidation, copper discolors over time. This is called patina. The material may also show some stains. These are natural properties of copper and do not have a negative effect on drinking from a copper object. Pure copper reacts with oxygen, water, and residues in water, such as sulfur. It actually means that the object has a high copper content and works well to purify the water.
