Diatomaceous Earth Test Results (NZ Source)
We have had our diatomaceous earth independently analysed to confirm its composition. The results below provide an overview of the material's properties.
Key Results
High silica (Si) content ~40.4%
Magnesium (Mg) ~0.050%
Iron (Fe) ~0.704%
Calcium (Ca) ~0.398%
Trace elements present in very low quantities
Lead (Pb), Mercury (Hg), and other harmful heavy metals not detected
What This Means
The results indicate a naturally occurring diatomite with a high silica composition and low levels of impurities. The absence of detectable heavy metals supports its suitability for a wide range of applications.
