escapekit:Australian SaltGermany-based photographer Kevin Krautgartner has captured the beauty of salt evaporation ponds, also called salterns. They are shallow artificial ponds designed to extract salts from sea water. To make it’s sea salt, many companies in Australia are using a method called “solar evaporation”. Solar salt is produced by the action of sun and wind on seawater in large ponds. The seawater evaporates in successive ponds until the seawater is fully concentrated and the salt then crystallizes on the floor of the pond. Due to variable algal concentrations, vivid colours, from bright blue to deep red, are created in the evaporation ponds. The colour indicates the salinity of the ponds. -- source link
