Celtic sea salt is obtained after the sea water is filtered from one pond to another in a natural network of 20 ponds. It is sun-dried, unrefined, unprocessed and with no additives. It is renowned because of its very high bio-available minerals content. This salt is composed of only 71 to 74 % of sodium chloride (ref Dr Brian Clement). This is why it is grey. This celtic sea salt is finer than the one in the tub.
