Definition: Natron was an important preservative the Egyptians used in their embalming process. In The Genesis of Science (2010), Stephen Bertman says Egyptologists use the term natron to refer to a variety of chemical compounds; specifically, sodium chloride (table salt), sodium carbonate, sodium bicarbonate, and sodium sulphate.

Natron worked to preserve the mummy in 3 ways:

  1. Dried the moisture in the flesh thereby inhibiting the growth of bacteria
  1. Degreased -- removed moisture-filled fat cells
  2. Served as a microbial disinfectant.

Examples: Natron was also used in the production of faience.
