This is a report of progress of an investigation concerning the effect of electrolytes on the liquid absorption of clays tempered to maximum plasticity. Data curves are presented to show that sodium silicates do have an influence on absorption when the silicates are added to the tempering water. The observed results are explained on the basis that the sodium silicate reduces the angle of contact and increases the adhesion tension of the clay‐water system. The results of this paper are suggestive of a possible extension of this principle to explain, a t least in part, some of the phenomena of deflocculation and plasticity.
