Caption December 2009: Harvesting solar salt from Lake Grassmere. By 1960, this type of harvester came into service, and has continued to be used, with some modifications. .................................................................................... SOLAR SALT FROM LAKE GRASSMERE Christchurch innovator-industrialist George Skellerup launched this wartime project in 1943. It took at least five years to prepare the pond, and get things running.
The locality was ideal, with a flat site by the sea, a shallow lake, only 585 mm of rain, plenty of sun, and dry evaporating winds.
Manufacturing salt at Lake Grassmere is a process of concentrating the salt content of seawater by evaporation, then harvesting the crystallised salt.
The salt forms crystals on the bottom of these ponds over the summer. In March, when the salt is ready for harvest, the remaining brine is pumped from the crystallisation ponds back into the sea. Before draining, the ponds are a bright pink-red, from the brine shrimps present.
