盐 盐是形声字。鹵为形符；监为声符。《说文》注：“碱也。从卤,监声。古者宿沙初作煮海盐。”“河东盐池，袤五十一里，广七里，周百十六里。”盐为具有咸味之一种矿物质。据说古 时齐灵公之大臣宿沙氏最先煮海水取盐。盐乃食盐之通称。具体可区分为海盐、井盐、岩盐。化学上指由金属离子（包括铵离子）与酸根离子组成之化合物。

<维基百科>资料:根据来源，盐可分为海盐、湖盐、井盐、石盐等几大类。其中海水和石盐是最主要的两个来源。石盐是内流盆地中封闭的湖泊蒸发所沉积下的矿物质。石盐的岩床可以在地下广大的区域里延伸，最多达350米厚。在美国和加拿大地下有一片巨大的岩床，从纽约州西部的阿巴拉契亚盆地起，通过安大略省地下，覆盖大部分密歇根州的地下区域。英国的柴郡地下和伍斯特郡周围有石盐矿。奥地利的萨尔兹堡因其盐矿，被称为“盐城”。中国江苏省淮安市地下有厚度为100-200米的盐矿，储量在世界首位。
盐加工的历史最早可追溯至约公元前6050年，前库库泰尼文化的人当时会使用陶器煮沸含盐的泉水，以提取其中的盐；而中国大约在同一时期也已有盐业存在.
中国井盐生产肇始于战国末年，李冰(在四川作郡守时)是其生产创始人.其他地方的食盐则是透过开采巨大的沉积矿藏而得，这些矿藏是数以百万年前的海洋和湖泊蒸发而成。

Salt [salt]
According to the source, salt can be divided into sea salt, lake salt, salt, rock salt, and other broad categories. The seawater and rock salt are the two most important sources. Rock salt is a mineral deposited in a closed lacustrine basin in an inland basin. The bedrock of rock salt can extend over a vast area of up to 350 meters. In the United States and Canada there is a huge underground rock bed, from the New York State western Appalachian Basin, through Ontario underground, covering most of Michigan's underground area. The Cheshire Underground and Worcestershire are surrounded by salt deposits. Salzburg, Austria because of its salt mine, known as the "Yancheng." Huaian City, Jiangsu Province, China has a thickness of 100-200 meters underground salt mine, reserves in the world.
The history of salt processing dates back to about 6050 BC, when former Kukuteni people used pottery to boil salt-containing spring water to extract the salt; and in China, salt was also present at about the same time .
Salt production in China began at the end of the Warring States Period, when Li Bing, the governor of Sichuan Province, was the founder of the production, and salt was extracted from the vast deposits of millions of years ago And lake evaporation.
