At Earthy Crunch UK, texture is one thing — safety is another.
Recently, I tested a sample of Terron Panela clay using a multi-parameter at-home water quality test kit. This post walks you through:
- The full results set
- What each reading means
- How the testing process works
- And the honest question: is it safe for consumption?
No drama. No scare tactics. Just facts — with a little earthy realism.
The testing process
Because clay is a solid earth material, it cannot be tested directly using water strips. Instead, the process involved:
- Crushing a representative sample
- Dissolving it into distilled water
- Allowing particulates to settle
- Testing the liquid portion using 30-second dip strips
These strips provide semi-quantitative screening results. They are designed for water testing, not mineral ingestion testing. That distinction matters.
They:
- Detect broad contamination indicators
- Have detection limits
- Are not laboratory-grade
- Cannot guarantee absence of trace contaminants
Think of them as a first-pass environmental screen, not a certification.
Full results set

Total hardness – 250 mg/L
Total alkalinity (carbonate) – 120 mg/L
pH – 7.6
Interpreting the results
Heavy metals
No detectable mercury, lead, copper, manganese, zinc or iron on the strip.
From a basic screening perspective, that is reassuring.
However, at-home strips cannot detect ultra-low concentrations. For definitive confirmation, laboratory ICP-MS analysis would be required. This was a screening test, not a forensic one.
Nitrate – 25 mg/L
For context:
UK drinking water legal limit: 50 mg/L
This sample: 25 mg/L
So, it sits below drinking water limits.
Natural clay materials interact with groundwater, minerals and environmental conditions throughout sourcing and formation. A moderate nitrate reading in an unrefined earth material is environmentally plausible — and not especially unusual.
Hardness – 250 mg/L
This indicates a strong mineral presence within the clay.
Anything over 180 mg/L is considered very hard water.
250 mg/L reflects substantial dissolved mineral content — exactly what you would expect from a dense, mineral-rich earthy clay.
In other words: mineralogically consistent.
Alkalinity – 120 mg/L
Alkalinity reflects buffering capacity.
Mineral-rich clays naturally contain compounds that increase alkalinity. Again, this aligns with what you would expect from a natural earth material.
pH – 7.6
Slightly alkaline. Entirely normal for mineral-rich clay material.
Nothing unusual here.
So… is it safe for consumption?
Here’s the grounded answer.
What these results suggest:
No obvious heavy metal contamination detected
No chlorine or industrial salt signature
Mineral profile consistent with natural clay
Nitrate present but below drinking water limits
What these results do not prove:
That the clay is free from trace heavy metals
That there are no pesticide residues
That it is microbiologically sterile
That it meets food-grade standards
At-home strip testing is a screening tool — not a food safety certification.
A realistic safety perspective
Natural clay materials carry inherent variables:
surface contamination
environmental pollutants
groundwater exposure
geographic and batch variability
Even if one sample tests clean, another batch may differ depending on sourcing conditions and handling.
For personal use, some individuals may feel comfortable consuming material that shows no detectable heavy metals on screening and moderate nitrate levels below regulatory limits.
For resale or public distribution, laboratory testing is essential. No shortcuts. No guesswork.
If you wanted to take safety further
Appropriate professional testing would include:
ICP-MS heavy metal analysis
microbiological screening
pesticide panel testing
moisture and stability analysis
This protects both the consumer and the seller — and sets a higher standard for transparency.
Final thoughts
From a mineral and sensory standpoint, the results look consistent with what many clay lovers would expect from Terron Panela:
Dense mineral presence.
A slightly alkaline profile.
No obvious contamination flags on basic screening.
The strong hardness reading also aligns with Panela’s signature texture experience — that dry sandy crumble, gritty crunch and thick muddy mouthfeel that makes it such a distinctive earthy clay.
But “consistent” is not the same as “certified safe”.
Natural clay products remain environmentally variable materials, whether hand-foraged or commercially circulated. That is why transparency, sourcing information and realistic safety discussions matter.
If you’re exploring earthy materials for sensory or hobby use, testing — even at a basic level — is a responsible step forward. It encourages awareness of what these materials actually are: raw earth products shaped by geology, groundwater and environment.
Texture is a craving.
Safety is a standard.
And both matter.
