Crystallisation ponds and salt piles
Salt makes up around three-quarters of the dissolved solids in sea water. The point at which salt begins to crystallise out of sea water is known as the ‘salting point’. Typically, this is when there is about 12% by weight of the original sea water left. Salt crystals form on the bottom of the crystallisation ponds at Lake Grassmere and link to form a white crust. This crust is harvested, crushed, and washed in brine to remove impurities. It is then stacked, ready for a host of different uses.
