The science of copper — and how to verify it yourself.
People have stored water in copper for thousands of years. Here’s what actually happens at the surface of the metal, the 5-second test you can run at home, and the independent lab verification behind every batch.
How it works
What copper does in water
Copper ions release into the water
Stored in a solid copper vessel, a trace amount of copper ions slowly migrates into the water — the basis of the centuries-old practice.
Ions disrupt microbes on contact
Those copper ions interfere with microbes they touch. Scientists call it the oligodynamic effect — a well-documented property of the metal itself.
You drink water stored the Ayurvedic way
Fill it at night, drink in the morning — tamra jal, the copper-water ritual kept for thousands of years.
We describe a well-studied material property, not a treatment — we make no medical claims.
Authenticity, in 5 seconds
The magnet test
A lot of “pure copper” bottles sold online are steel, coated to read as the real thing. You can screen any of them in seconds.
Hold a magnet to the bottle
Press a small magnet against the bottom or side of any “copper” bottle — including ours.
Pure copper is non-magnetic
Solid copper won’t cling to a magnet. It simply slides off — nothing to grab onto.
If it grabs, it’s steel
A magnet that holds means there’s magnetic steel under the finish — coated or plated to look like copper.
The magnet is a quick screen, not a lab — some steels are only weakly magnetic. That’s why we don’t stop there: every batch is independently lab-tested for purity.
Proof, not promises
We send a sample from each batch to an independent lab.
Talk is cheap, so we don’t ask you to take our word for it. Every production batch is sampled and tested for purity by an independent lab — confirmed as solid copper, with no inner lining, no nickel, and no plating.
