A bstract Two red‐firing Iowa brick clays were analyzed for sulfate (SO 4 − ) content by a method suitable for plant‐control tests. From this datum the amount of barium carbonate required to react with this ion can be calculated. Plasticity measurements on (1) samples treated with the amount of barium carbonate indicated by SO 4 − analysis, (2) untreated samples, and (3) samples treated with normal plant additions show significant differences in this property. These differences can be explained using the modern concepts of the factors which influence the zeta potential.
