Bilma, an important town in the Kaouar, owes its peculiar social and commercial traditions to its difficult geographical location. The picture shows a woman shaping "salt loaves", so-called "household packs". In fact, this quantity is used by families as a unit of account, much like the sugar stick, and it is remarkable that consumers often do not know the weight of either. More extensive forms of trade are brought by caravans to Agadez and are mainly used for animals. - Kaouar - Ténéré - Niger - 1968

The grey-yellow kantu, which are produced in cone form as cattle salt and weigh about 25 kg, are reminiscent of slightly oversized traffic pylons. The shape comes from the fact that hollowed-out palm stalks serve the salt workers as moulds for drying the salt. About three quarters of the salt produced is made as Kantu salt. - Bilma - Kaouar - Ténéré - Niger - 1968

The shape comes from the fact that hollowed-out palm stalks serve the salt workers as moulds for drying the salt. Another product form of salt is the so-called fotschi (foschi) (in the background), salt loaves shaped by women in enamel bowls, weighing up to about 2 kg and mostly consisting of beza, crystallised, relatively pure salt that is used as table salt. About three quarters of the salt produced is kantu salt, one quarter is beza salt. - Bilma - Kaouar - Ténéré - Niger - 1975

Packing the blocks requires a special skill and is done while the traders discuss the terms of the trade. Once an agreement is reached, the salt blocks are loaded onto the camels. - Bilma - Kaouar - Ténéré - Niger - 1975

The picture shows people in the ‘Salar de Coipasa´ in Bolivia, which, at over 10,000 square kilometres, is the largest salt flat on Earth. In the foreground is a small makeshift hut – or rather an igloo – made of salt bricks, in front of which people are standing. In the background, the Andean volcanoes (such as the well-known Tunupa volcano) can be seen, surrounding the flat, white salt pan. – Bolivia – 1976

Workers engaged in traditional salt extraction on the bright salt crust of the Salar de Coipasa. They break off and stack blocks of salt from the crust using simple tools such as poles and shovels. Historically, these blocks were used as a durable building material for the famous salt hotels and other accommodation, as well as salt licks for livestock (llamas and alpacas). The people are wearing warm, protective clothing and hats, as the climate at these high altitudes is windy and cool. – Bolivia – 1976
