Casting aluminium cooking pots: labour, migration and artisan production in West Africa's informal sector, 1945–2005
This article investigates the history of aluminium casting, a sector of the informal economy devoted to recycling scrap aluminium. Artisans who cast aluminium make a variety of products out of scrap, including various utensils and receptacles for food preparation, such as cooking pots. While labour and its history in West Africa has garnered much historical research, as has the work of artisans who specialise in working other types of metal, especially iron, little attention has been paid to aluminium casting. The oversight is significant, because the diffusion of aluminium casting opens up a history on the transnational movement of labour and artisan production in late colonial and post-colonial Africa.
