Our Glazes: Tested for Safety at an NABL-Accredited Lab
We test our glazes for lead and cadmium release per ISO 6486.
Lab test reports can be shipped at additional cost.
Never a second thought.
Why glazes matter
Everything we make touches food. The glaze is the part of a bowl, mug, or plate that meets your hands, your kitchen counter, and what you eat off. It is also the part most likely to contain metal oxides, since colour and shine in ceramic glaze often come from mineral compounds that can include lead and cadmium in trace form.
That is why we treat glaze differently from the rest of the product. We do not assume a supplier's word is enough, and we do not assume a glaze is safe simply because it has long been used in ceramics. We test it.
What we test
- We test our glazes for lead and cadmium release per ISO 6486, the standard method for measuring release from ceramic ware intended for food contact.
- Testing takes place at an NABL-accredited laboratory.
- Tested glazes are re-tested annually.
- Batch testing is available on demand for institutional orders.
What the results show
Four of our glaze lines have completed testing so far: Folklore, Solitude, Sands Dune, and Sand Dusk. For each of them, the result for both lead and cadmium release was the same: neither was detected.
We name the glazes that have completed testing rather than making a blanket claim about the range. A glaze that is not named above has not completed testing, and we would rather say that plainly than let a general claim cover it.
Most ceramic glazes sold in India are never tested. We test ours at an NABL-accredited laboratory.
What you can ask any ceramics brand
Testing should be the honest standard for anything that touches food, not a point of difference. Before you buy ceramics anywhere, it is reasonable to ask:
- Has the glaze been tested for lead and cadmium release, or only the finished piece assumed safe?
- Does a test report exist for the glaze in question, or only a general safety claim on the listing?
- Is testing repeated over time, or done once and never revisited?

Questions
What does "NABL-accredited laboratory" mean?
NABL is the National Accreditation Board for Testing and Calibration Laboratories, the body that accredits testing labs in India. A lab holding NABL accreditation has been assessed against a recognised technical standard for testing competence.
What exactly do you test for?
We test our glazes for lead and cadmium release per ISO 6486. Testing is repeated annually, and batch testing can be arranged for institutional orders.
Which glazes have completed testing?
Folklore, Solitude, Sands Dune, and Sand Dusk have completed testing, and in each case neither lead nor cadmium was detected. A glaze that is not named here has not completed testing, and we do not claim otherwise.
Can I see the test report?
Yes. Lab test reports can be shipped at additional cost, write to contact@claymistry.in and we will confirm the cost.
Why test the glaze rather than just the finished piece?
Glaze is where food-contact risk concentrates, so we test the glaze itself rather than relying on a general claim about the finished product.
Is this testing unusual in the Indian ceramics market?
Most ceramic glazes sold in India are never tested. We test ours at an NABL-accredited laboratory, and we think that should be the standard, not the exception.
