In Ayurveda that is called tamra jal, copper water, and there it is not an afterthought but the fixed opening of the day. Where the tradition comes from, and what can reasonably be said about it, is set out in \u003ca href=\"\/blogs\/knowledge-base\/tamra-jal-the-ayurvedic-tradition-of-drinking-water-from-copper\"\u003ethe article on tamra jal\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eNine hundred millilitres is a deliberate size: enough for a full morning portion with a second glass after it, and still a bottle that fits in a bag.

Smooth gives an even surface that reflects the light in a single plane. Hammered is worked by hand, so every piece has its own pattern of dents that breaks the light. The copper underneath is the same either way. Both are formed from a single piece of copper, with no seam and no solder, so your water touches nothing but copper.\u003c\/p\u003e\n\u003ch3\u003eHow to get the most out of your copper\u003c\/h3\u003e\n\u003cp\u003eStill water goes in, and nothing else. Carbonated water, lemon juice, sports drinks and vinegar are acidic enough to dissolve copper faster; pour those into a glass.

Rinsing with warm water is usually enough, and a slice of lemon with salt (not too hard: salt is mildly abrasive and dissolves well in the lemon juice) brings the shine back now and then.
