Despite the origination of new leather making techniques such as chrome tanning which is being employed extensively today, the traditional method of leather production primarily through vegetable tanning is still being practised mostly in artisanal tanneries in developing nations including Ghana. Artisanal leather making, thus, contributes beneficially to rural livelihood. Nevertheless, the growth of this sector has been stifled by the lack of innovative technologies to enhance productivity. This challenge could be partly linked to the knowledge gap on the scientific principles governing artisanal leather production processes. This study, therefore, elaborates on various process steps and materials employed in traditional leather making in Ghana and the scientific principles underlying each of the processes. It also makes a comparison between traditional and modern leather manufacturing processes and identifies knowledge and technological gaps which would inspire in-depth scientific research into artisanal leather making.

The suitability of leather as an alternative material for sustaining vessel production in Ghana / Baidu K. A. O. in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. CXIV, N° 12 (12/2019)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. CXIV, N° 12 (12/2019) . - p. 462-469 Titre : The suitability of leather as an alternative material for sustaining vessel production in Ghana Type de document : texte imprimé Auteurs : Baidu K. A. O., Auteur ; Essuman E. K., Auteur ; Asubonteng K., Auteur ; Boahin J.O.B., Auteur Année de publication : 2019 Article en page(s) : p. 462-469 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Cuir Cuir -- Séchage Cuir, Travail du Cuirs et peaux -- Industrie -- Ghana Récipients Tannage végétal Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Anecdotal evidence and a further report from leather experts show that there is close to no enlightenment of the production of leather vessels in Ghanaian leather industries. This study was, therefore, conducted as a result of the need to add leather as supplementary material to the traditional materials such as clay, metal, wood and half-gourd used for producing vessels in Ghana. The purpose of the study was to find out how Ghanaian indigenous leather could be used in the production of leather vessels. The qualitative study employed three key techniques, namely : 'Cuir bouilli' leather hardening methods, the sand pounding technique, and assemblage and construction technique. Based on the results, the baking and hot wax methods adversely affected the indigenous leather positively in the hardening of the leather. The results also show that using only one part of the leather (the back, belly or butt) affected the quality of the leather vessels, but incorporating the various parts of the hide helped improve the quality and durability of the leather vessels. The implications of the results and future research directions are also presented. This study has, therefore, expanded the usefulness of the Ghanaian indigenous vegetable tanned leather apart from the conventional usage for making shoes, bags and belts.
