You fill it in the evening, let it stand, and pour for everyone at once the next morning. Where that practice comes from 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\u003eIt has a matching copper lid, and that is not decoration: water left on the counter overnight is water left open overnight. The lid keeps dust and insects out. The spout is narrow enough to pour without spilling, and the handle stays cool enough to hold.\u003c\/p\u003e\n\u003cp\u003eThe jug comes \u003ca href=\"\/blogs\/knowledge-base\/smooth-or-hammered-copper\"\u003esmooth and hammered\u003c\/a\u003e. At this size the difference is easy to see: the smooth surface gives one continuous reflection, while the hammered piece spreads the light across dozens of small facets. The jug, spout included, is formed from a single piece of copper, with no seam. The handle is brazed on separately, on the outside. Nothing of that joint reaches the inside, so your water only touches the copper jug itself.\u003c\/p\u003e\n\u003cp\u003eThere is another reason copper became the tradition. In EPA tests, cleaned copper killed more than 99.9% of bacteria such as MRSA and E. coli within two hours, and since 2008 it has been registered in the United States as an antimicrobial material. It is also a trace element your own body uses, from energy metabolism to the transport of iron in your blood. Stainless steel and plastic are inert and do neither. The evidence is in \u003ca href=\"\/blogs\/knowledge-base\/can-copper-really-kill-bacteria-the-evidence-from-epa-to-southampton\"\u003ecan copper really kill bacteria\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eHow to get the most out of your copper\u003c\/h3\u003e\n\u003cp\u003eStill drinking water goes in the jug. Fruit juice, squash and carbonated water are too acidic for copper. Refresh the water daily rather than leaving it standing for days.\u003c\/p\u003e\n\u003cp\u003eWash jug and lid by hand and dry them straight away; standing moisture is where the first marks start. Because a jug has far more surface than a cup, you also see copper's natural darkening sooner here.
