How Natural Sea Salt Is Made
The process of making sea salt the traditional way can be
considered simple, in the sense that it is a manual process, performed without the help of machinery.
But on the other hand, it is a complex process that requires a wide knowledge on a variety of topics. Perhaps without knowing it, the person in charge of a saltworks is simultaneously an artisan, a chemist, an engineer, a meteorologist and a mathematician. In addition to those qualities the person must possess the traits of a farmer… i.e. patience, endurance and perseverance.
Preparing the ponds and harvesting the salt is hard work. Long days in the hot sun and heavy loads are the norm. Yet there is a definite sense of passion for the work and it is not uncommon to see men and women even in their 80’s preparing the ponds, checking on the progress of the waters and harvesting the fruit of their labors.
The process of making salt is an art and a science. The usage of the waters must be planned in advance so that new waters are ready for the crystallization ponds when the old water is spent. Advancing the water through the successive ponds requires
measuring the salinity of the water. The degree of salinity of the brine will determine when the various elements in the brine will start to precipitate. This is important information when one wants to maximize the amounts of important elements such as calcium, magnesium and potassium in the final product. The purity of the brine or feedstock, would also determine the purity of the natural sea salt at harvest. This is critical in our operations.
In addition, the company has developed a hybrid method, which combines both solar and thermal energy to produce a consistent quality of both salt crystals and salt flakes.
Finally, before the concentrated brine leaves the Concentrating Pans, it is “washed” to remove all deposited of naturally occurring Calcium Carbonate and Calcium Sulphate that would have crystallized and deposited at the bottom of the pans as well as residual dirt.
The “washed” brine is then transferred into the Crystallizers, where the salt finally crystalizes out of the brine, for harvesting.
At this stage, it is pure white salt, ready for drying and bagging.
