It has been confirmed that the disordered hematite occurring in prehistorical red colouring material has not a natural origin. A heat-treating allows to verify the identification thanks to a different behaviour of natural hematites which have other crystalline anomalies.II a été confirme que l'hématite désordonnée présente dans certains colorants rouges préhistoriques n'était pas d'origine naturelle. Un traitement thermique permet de vérifier son identification en la différenciant des hématites naturelles présentant d'autres anomalies cristallines.Périnet Guy, Onoratini Gérard.
