ABSTRACT:
An improved moisture absorbing amorphous silicate material formed by the steps of: parboiling rice under 22 psi and at a temperature above 212 degrees F. to force bran into the rice grain and dissolve cellulose from the rice hulls creating voids in the rice hulls; drying the parboiled rice; milling the parboiled rice into grain, bran, and broken rice hulls; separating the broken rice hulls from the grain and bran; and burning the broken rice hulls at high temperatures to produce a skeletal residue of amorphous silicate material. Several uses of the amorphous silicate material are disclosed.
