It is used for foundry molding, in tooth pastes, face powder and facial mud packs...

This phenomenon, though familiar in organic substances, was not previously known to occur in minerals such as clay.* Dr. Hauser's theory is that the bentonite clay particles are electrically charged, and so line up end to end in chains...
