This module discusses methods of obtaining table salt from seawater. Topic areas considered include: (1) obtaining salt by solar evaporation of seawater in holes; (2) obtaining salt by boiling seawater in pots; (3) how table salt is obtained from seawater in the Philippines; and (4) methods of making salt by solar evaporation of seawater in the Philippines (such as using concrete ponds, polyethylene ponds, and bamboo rafts). Procedures (accompanied by illustrative diagrams) for using these methods are included. The method selected depends on the available materials, capital, and place for solar evaporation. (JN)
