盐是源于地下矿物的淤积物,源于盐湖和盐水泉,以及源于海水等,当然就别指望在制盐技术方面会出现一致性。既然岩盐能够被采掘,或者给岩盐加水而生产出一种人工盐水;海水能够用日光照射的方法使其蒸发,或用人工的方法使其煮沸,等等,因此对于每一种盐源都有许多制取食盐的方法。尽管运输条件简陋,那些小的地区内,还是广泛采 Salts are silts that originate from underground minerals, from salt lakes and salt springs, from seawater, and of course do not expect consistency in salt-making techniques. Since rock salt can be excavated or water can be added to the rock salt to produce an artificial salt water, the seawater can be evaporated by sunlight, or be artificially boiled, and so on, for each salt source Many ways to make salt. In spite of the crude transport conditions, those small areas are still widely adopted
