ABSTRACT:
A particulate amorphous alkali metal silicate is prepared by heating a mixture of silicate glass and water or aqueous solution to a temperature of about 300.degree.-400.degree. C. to provide a foamed material that is easily formed into particles of less than 20 microns. After careful hydration, a product having 1-15% water based on loss of ignition (LOI) of product at 800.degree. C. is produced that controls the activity of magnesium in solutions and is, therefore, a useful detergent ingredient.
