Making of Aluminium Cooking Pots in Cité Soleil, Haiti

Image by United Nations Photo
30 years ago Mones Mondasar’s father, established himself as an aluminum cooking pot maker in Port-au-Prince’s Cite Soleil, Haiti’s largest and most infamous slum. Now 45, Mondasar and his 25 year old son Walnes, continue the tradition producing up to 10 pots a week. It’s a small number by modern manufacturing standards, but everything depends on what scrap aluminum can be collected to be melted down and poured into hand made sand molds. The finished product will bring 500 Haitian Gourds each – approximately US – in Port-au-Prince’s central market.
