"Soda, Clay and Fire" Gail Nichols


Michael,

Here is the book by Gail Nichols. She describes the process of mixing the whiting, light soda ash and sodium bicarbonate on page 8 - 11. She says that it is the light soda ash that causes the reaction. The whiting and sodium bicarbonate are not involved. She found this out by leaving them out and only the absence of the light soda ash caused the mixture not to harden.

It is an interesting read. Tons of info!
