Observation is not certification
Material comparisons here are qualitative prompts. They do not establish fire performance, structural suitability, toxicity or fitness for a product. Consult the information for your actual sample and obtain appropriate expertise for consequential decisions.
Keep experiments proportionate
Work with familiar materials and suitable handling precautions. Unknown powders, coatings and fibres require separate assessment. The illustrative scenes do not demonstrate a real accredited laboratory or a promised test outcome. Apply exercises to your own work without claiming another person’s materials or results.
