{"product_id":"kopero-premium-koperen-waterfles","title":"Kopero Copper Water Bottle","description":"\u003cp\u003eThis bottle is made for one habit: fill it with still water in the evening, let it stand overnight, and drink it first thing the next morning. 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\/kennisbank\/tamra-jal-de-ayurvedische-traditie-van-water-drinken-uit-koper\"\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. It stands upright on a desk, fits beside a bed, and opens with one hand.\u003c\/p\u003e\n\u003cp\u003eYou choose between smooth and hammered. 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.\u003c\/p\u003e\n\u003ch3\u003eWhat to watch out for\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; drink those from glass or stainless steel. How much you can sensibly drink from it per day, and why there is an upper limit, is covered in \u003ca href=\"\/blogs\/kennisbank\/hoe-vaak-per-dag-zou-je-uit-een-koperen-fles-moeten-drinken\"\u003ehow often per day you should drink from a copper bottle\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eThe bottle is not dishwasher safe. Rinsing with warm water is usually enough, and a slice of lemon with salt brings the shine back now and then. The full routine is in \u003ca href=\"\/blogs\/kennisbank\/koperen-fles-onderhouden-schoonmaken-polijsten-en-bewaren\"\u003ethe care article\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eAnd it will darken. Uncoated copper reacts to air and moisture and grows darker over the weeks, sometimes with green or black patches. That is normal, it is reversible, and it is also the clearest proof that there is no lacquer over it.
