The production of iron and its processing are well represented among the Ngambaye people’s activities, the latter living in the heights of the Logone River valley in the southern part of Chad. Practiced since the colonial period, iron production and processing is a know-how which contributes to generate financial resources deemed necessary for the survival of the local population. It is in the midst of field work sessions that we have been able to collect the necessary information from the traditionalists. Within an oral tradition society like this one, the teaching method of the history of this ancestral skill is done through hear-say techniques and from one generation to the other. One of the tenets of its imparting is the constant use of sayings and proverbs in the current language. It is true though, that the primary metalwork (the production of iron from ores) is no longer practiced since the 1950’s, and that its secondary metalwork (the transformation of the semi-end-product into end-product) is less and less practiced. But these two models of transmission of the history of iron in ngambaye territory are currently in use, especially in rural areas.
