What home tests can and cannot show
Texture, solubility and temperature response may describe how a sample behaves, but many different substances can imitate those behaviours. A home test cannot identify heavy metals, microorganisms or every form of adulteration.
More useful checks
A better buying decision combines product identity, commercial traceability and relevant testing.
- A clear ingredient declaration
- A batch or lot identifier
- A test date that matches the commercial period
- A laboratory or testing body that can be identified
- A seller willing to explain the report in plain language
Why colour alone is not enough
Natural materials can vary. Colour and thickness can also change with temperature, moisture and processing. They should not be used as the only proof of authenticity.
