**7. Conclusion**

Analytical techniques IR-TF and HPLC-UV-Visible and microchemical tests applied to the study of dyes and pigments extracted from samples taken from ethnic objects including masks (Guèlèdé), statues of Ibéji, fetish and textiles from museum collections, provided, among other things, information on the matrix origin of materials than on the techniques used in their making. The dyes identified on the objects presented as an example are mostly of plant origin. They reveal the results of the entire corpus of objects studied and testify to the knowledge and use of local natural resources in the making of ethnic objects. However, natural mineral pigments such as kaolin, and soils rich in iron oxides, as well as two synthetic blue pigments have been identified on certain objects. Apart from the dyes, the binders reported in the manufacture of heritage objects come largely from the plant world, nevertheless binders to the whole egg or part of the egg were also reported during field surveys and highlighted. Regarding the way of African painting, it was observed that the color can be directly applied to the wood and then be covered with a resin or a tree sap (or conversely, the resin of first applied to the wood underlay). It can also be applied in two layers of different dyes. In addition, the application of dyes to specific places on the object, in particular the shade affixed to the heads, the dorsal column, or the face, denotes coded know-how which reveals that their use goes beyond the mere decorative function.
