When a solution of sodium silicate or water glass is mixed with an acid sooner or later a gel is formed. The speed of gelation is known to be dependent upon the concentration of water glass, the excess of acid or alkali present, agitation, temperature, and the kind of acid used. In my work with the setting of the gels these five points were kept as constant as possible.
