Natron

Natron is a naturally occurring mixture of sodium carbonate decahydrate (Na₂C O₃·10H₂O, a kind of soda ash) and about 17% sodium bicarbonate (also called baking soda, NaHCO₃) along with small quantities of sodium chloride and sodium sulfate. Natron is white to colourless when pure, varying to gray or yellow with impurities. Natron deposits are sometimes found in saline lake beds which arose in arid environments. Throughout history natron has had many practical applications which continue in the wide range of modern uses of its constituent mineral components.
