Embalming
*Body packed with a “salt” called natron for forty days
*Natron is a naturally occurring mixture of sodium carbonate decahydrate (Na2CO3·10H2O, a naturally occurring form of soda ash) and about 17% sodium bicarbonate (also called nahcolite[1] or baking soda, NaHCO3) along with small quantities of household salt (halite, sodium chloride) and sodium sulfate. Natron is white to colorless when pure, varying to gray or yellow with impurities. Natron deposits occur naturally as a part of saline lake beds 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.
