What needs to be clarified
The analysis could describe the objects, their structural relationship and suitability for comparison. Composition, inclusion origin and possible contact require different materials.
Materials to prepare
- The product with inclusion positions preserved and discovery circumstances recorded.
- Overall and local photographs, composition labels, purchase records and available manufacturing descriptions.
- Storage, use, cleaning and handling information, plus comparison samples of documented origin.
What to compare
- Whether differing hairs occur within the structure or only on accessible surfaces.
- How objects are distributed and whether features recur across several areas.
- Which features permit comparison and what further methods the question requires.
Possible outcome of the analysis
A possible output is an object-group description, location diagram and justified further checks. Structural observations would be separated from hypotheses about particle transfer.
Limits of the conclusions
Individual hairs may not establish species or a specific source. Similarity does not automatically determine transfer time or mechanism, or the composition of every fibre.
