High Quality Content by WIKIPEDIA articles! Natron is a naturally occurring mixture of sodium carbonate decahydrate (Na2CO3·10H2O, a kind of soda ash) and about 17% sodium bicarbonate (also called nahcolite or baking soda, NaHCO3) along with small quantities of household salt (halite, 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 still resonate in the wide range of modern uses of its constituent mineral components.In modern mineralogy the term natron has come to mean only the sodium carbonate decahydrate (hydrated soda ash) which makes up most of the historical salt.
