Using Salt and Natron
When Making an Animal Mummy
No matter which mummy recipe you follow, the instructions usually tell you to use salt. This is an easy substitute for natron, the salt-like substance used for making mummies by the ancient Egyptians.
But Mrs. Jockisch's core class in Orinda, CA, suggested the following: "We have found that it is a good idea to mix a little baking soda with the salt to cut down on the odor. It also helps to leave the bags open so that the excess moisture can evaporate! We also added sprigs of rosemary to the whole mixture to give it a rather nice smell... well kinda nice smell. It did help cover the chicken smell a bit."
If you'd like to substitute natron for salt in the chicken or mouse mummy recipes on this website, you don't have to go to Egypt to buy it. Instead, you have two options:
1. Go to your local grocery store and look for a box of Arm & Hammer's Washing Soda in the detergent aisle. This is "sodium carbonate"--the very compound that comprises natron.
2. Go to your local swimming pool supply store and buy some sodium carbonate (called "soda ash").
