Between hell and heaven... purgatory... For 35 years, Saliha has been dipping aluminum foil in sulfuric acid and caustic soda. It's a necessary process to anodize (create a protective layer) aluminum foil before transforming it into pots, pans, or kettles. The smell is unbearable. The toxic fumes burn eyes. With a simple scarf on her face, she works all day for a salary of 3€ per day. Aluminum factory in Dacca, Bangladesh.
