#### Soda ash, the commercial name for sodium carbonate ($\displaystyle N{{a}_{2}}C{{O}_{3}}$), is a white, anhydrous, powdery or granular material.

It is an essential raw material used in the manufacture of glass, chemical detergents and other industrial products.

As such, soda ash is one of the most used and important products in the United States, contributing substantially to the gross domestic product. For this reason, the Federal Reserve Board incorporates monthly data on soda ash production into the monthly economic indicators used to monitor the situation of the US economy.

Sodium carbonate has been used in manufacturing for over 5,000 years. The ancient Egyptians used it to make ornaments of glass and vessels. They recovered the product from deposits of dry lake beds or burning seaweed and other marine plants. The Romans also used soda ash to bake bread, make glass and for medicinal purposes. Its extraction from the ashes of several plants continued until the mid-nineteenth century and gave it the current name of “soda ash”.
