Lab Test Results
Anyone can print pure copper on a label. We sent our copper to an accredited independent laboratory instead, and this page shows exactly what came back.
Result: lead was not detected. Neither was cadmium, mercury, nickel, arsenic or chromium.
Tested by Spectro Analytical Labs, part of Eurofins Scientific, against European food contact regulation EU 10/2011. Both samples passed.
What was tested
Two finished pieces went to the laboratory, taken from the same production our artisans make for us:
- A hand hammered copper water bottle, 950ml
- A copper water dispenser vessel
These are the pieces themselves, not a copper sample or a raw sheet. The laboratory tested what actually holds your water.
How it was tested
The test is a migration test, which is the one that matters. It does not ask what the metal is made of. It asks what comes out of the metal and into your drink.
Each piece was filled with 3 percent acetic acid and left at 40 degrees for 10 days, which is a deliberately harsh stand in for years of ordinary use. The liquid was then analysed by inductively coupled plasma mass spectrometry, which detects metals down to hundredths of a milligram per kilogram.
Method: BS EN 13130 Part 1, 2004. Analysis by ICP-MS.

What "not detected" actually means
It does not mean nobody looked. It means the instrument looked as far down as it can see and found nothing there.
For lead, cadmium, mercury, nickel and arsenic the detection limit was 0.01 mg/kg, which is one hundredth of a milligram in a kilogram. Below that, there was nothing to report.
Who did the testing
Spectro Analytical Labs Private Limited, part of Eurofins Scientific SE, at E-41 Okhla Industrial Area, Phase II, New Delhi.
The laboratory is NABL accredited under TC-10245 and certified to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018. Eurofins is one of the largest testing groups in the world and has no commercial interest in the result.
Samples were received on 30 June 2026. Testing ran from 1 to 13 July 2026. Reports were issued on 21 September 2026 under job number N260630018.

Common questions
Why bother testing at all?
Because copper drinkware is sold online with almost no checking behind it, and lead in brazing alloys and solder is a known problem in cheap copperware. We wanted to know, and once we knew we thought you should be able to see it too.
Does this cover every piece you sell?
The pieces tested are representative of the copper our artisans work with across the bottle and dispenser ranges. They are not a certificate for every individual item, and we would not claim otherwise.
Is the copper lined or coated inside?
No. The inside is bare copper, which is why it darkens over time. Lemon and salt, or a copper cleaner, brings the shine back.
How do I know it is copper and not plated steel?
Hold a magnet to it. Copper is not magnetic, so a magnet will not stick. On plated steel it grabs straight away.
