12th century – 15th century
Niani, Guinea
Iron objects excavated at Niani in Guinea underwent chemical analysis that identified copper, phosphorus, nickel, tungsten, titanium, and molybdenum as impurities. The composition was interpreted as probably reflecting the ores used to produce the artefacts. The example illustrates how archaeometric analysis can investigate ancient metallurgy and material provenance.

The Story
Iron objects discovered at Niani in Guinea were subjected to chemical analysis rather than being interpreted solely from their appearance. The examination identified copper, phosphorus, nickel, tungsten, titanium, and molybdenum among the impurities present in the metal. These elements were considered likely to have originated in the ores from which the iron was produced.
The case demonstrates the evidentiary value of ordinary chemical analysis in archaeological metallurgy. Impurities preserved in an iron artefact can provide clues about the raw materials and production environment behind it, even when the original ore sources are not directly observed. Such results contribute to the reconstruction of technical practices and material networks.
Niani is presented here not through a political history, but through the laboratory study of excavated objects. The example belongs to a wider methodological argument: scientific results are most useful when combined with stylistic, philological, and stratigraphic considerations. The extract does not identify the excavated objects individually or establish a precise archaeological date for them.
