Red Hill (salt making) is a process that people have used for thousands of years to make salt. It is simple but can take several days. First, seawater is boiled in big pans until all the water has evaporated and only crystals of salt are left. The salty crystals are then collected and stored. The process takes several days and relies on the sun to help speed up the evaporation process. In the end, you get pure salt that you can use for cooking, preserving food, and other tasks.
