When the salt fields were initially developed, the lagoons and sand bars at Szutsao Lake in Anping were mainly employed. Using basalt and coral rock from Penghu for dikes, the seawater was first channeled into large evaporating ponds. After initial evaporation, the briny water was channeled into small evaporating ponds where it was further concentrated, and the resulting black brine was channeled into crystallization ponds where exposure to the sun yielded crystallized salt.
鹽田的開闢，主要利用安平四草湖的潟湖與沙洲，以澎湖來的玄武岩與咕咾石築堤，先將海水引入大蒸發池，再將初步蒸發後、鹽度較高的海水引入小蒸發池，濃縮成鹽鹵，最後再將鹽鹵引入結晶池，曬成結晶鹽。
