<This unique handmade cup in a curved design with a sequence hammered edge is made of pure copper. The cup has a capacity of 300 ml. </p> <p>Ayurveda has advocated the benefits of drinking water from copper drinking vessels since ancient times. Ayurveda states that keeping water in a copper bottle or cup for 8-10 hours has a balancing effect on the three bio-energies (doshas) circulating in the human body (Vata: air element, Pitta: fire element and Kapha: water element). Additionally, water in copper drinking vessels turns into naturally alkaline water, which helps balance your body's pH. <a href="https://www.ayurveda specialist.nl/water-met-de-kracht-van-koper/"><strong>Read more here</strong></a></p> <p>Copper discolors over time due to natural oxidation. This is called patina. The material may also show some stains. These are natural properties of copper and there is no negative effect on drinking from a copper object. Pure copper reacts with oxygen, water and the residues in water, such as sulphur. Rather, it means that the object has a high copper content and works well to purify the water. Discoloration of the inside is not harmful. If the discolouration becomes too severe, you can clean the bottle, jug, water tank or cup. </p> <p> </p> <p> </p><p>Copper drinking vessels are only suitable for water, not for milk, citrus juices, or acidic liquids. </p> <p>Do not wash in the dishwasher. Clean with natural soap, soft sponge and room temperature water. Do not expose to direct sunlight. </p> <p>Our unique copper drinking bottles, jugs, water tanks and cups have been handmade in India for centuries. Precisely because it is handmade, each item is unique and may therefore differ slightly from the photo. There may also be imperfections in the material: this is part of the natural properties of copper. </p> <p><a href="https://www.ayurveda specialist.en/how-do-i-clean-my-copper-drinking-equipment/"><span style="font-size: 20px;"><strong>Click here for an explanation of how to clean copper</strong></span></a></p> <p><a href="https://www.ayurveda specialist.how-do-i-clean-my-copper-drinking-ware/"><img class="alignnone wp-image-45546"
