Questions, answered honestly.

Yes. Pure copper oxidises — that is normal and, in Ayurvedic thinking, part of how the object lives. To bring back the shine, rub with half a lemon and a little salt (or a paste of salt and tamarind) once a week, then rinse — or let it patina. Both are correct.

No. Every piece of copperware we sell is pure, unlined, unlacquered copper — the traditional specification. We do not use tin-lined copper (that is kitchenware-grade but breaks the practice).

Please do not. Hot water and dishwasher detergent strip copper fast. Hand-wash with warm water, and bring back the shine with lemon and salt once a week.

The bottles and dispenser are for water only — copper reacts with acidic or fermented drinks. The tumblers and mule mugs are made for cold drinks; if you serve anything citrus-based in them, rinse them soon after.

Ayurvedic practitioners have valued the practice — tamra jal — for thousands of years, and that heritage is why we love it. We won’t promise it will change your health; what we will promise is softer-tasting water and a ritual worth keeping. For specific health questions, speak to a qualified practitioner.

Traditionally 8 hours or overnight. Pour fresh water in the evening, drink it in the morning.

For a typical adult drinking from a copper vessel stored overnight, yes. If you have a copper-related medical condition (e.g. Wilson's disease), speak to your doctor first.
