On Saturday 20th June members of the PL Chemistry club presented a sample of sea salt to a visiting delegation from Newbattle Abbey College. The delegation followed the Salter’s Way, the route traditionally taken by the Cistercian Monks from their Abbey at Newbattle to Salt Prestoun (modern day Prestonpans) from 1198. These monks came year after year until their Abbey was dissolved in 1560. They used the readily available coal to boil the sea water using 2 tonnes of coal to produce 2 tonnes of salt.
PL Chemistry Club were challenged to replicate the conditions used by the original Salters and produce pure salt from sea water. This was carried out by filtering and recrystallising crude salt derived from the sea in Prestonpans.
