Introduction

Salt is a common colorless or white substance that is found both in sea water and in deposits in the earth. Animals including humans need salt in their diets. Salt is used to season and preserve food. It is also used in making soap and glass.
Since ancient times, salt has been used to flavor and preserve food. Early trade routes and many of the first roads were established for transporting salt. Many ancient civilizations levied taxes on salt. Salt was considered so precious that it was traded ounce for ounce for gold.
In ancient China, coins were made of salt. In the Mediterranean regions, salt cakes were used as money. Ancient cities such as Genoa, Pisa, and Venice became salt market centers. By the fifteenth century, salt was obtained by boiling brine from salt springs, and many towns and cities in Europe located near such sources. During the eighteenth century, the efficiency of the boiling brine process was improved by using coal instead of wood as fuel. Because of its coal supply, England became the leading salt producer in the world.
