» Prepare Bentonite Magma as follows:

Sprinkle the Bentonite, in portions, upon 800 g of hot purified water, allowing each portion to become thoroughly wetted without stirring. Allow it to stand with occasional stirring for 24 hours. Stir until a uniform magma is obtained, add Purified Water to make 1000 g, and mix.

The Magma may be prepared also by mechanical means such as by use of a blender, as follows. Place about 500 g of Purified Water in the blender, and while the machine is running, add the Bentonite. Add Purified Water to make up to about 1000 g or up to the operating capacity of the blender. Blend the mixture for 5 to 10 minutes, add Purified Water to make 1000 g, and mix.
