The chlor-oxy-hydroxy magnesium compounds collected in Settling Pond 4 are also dissimilar from Sorel cement in that the ratio of magnesium to chlorine by weight always exceeds 2.5 whereas in Sorel cement the ratio lies between 0.6 and 2. In addition Sorel cement will not form in dilute solutions and in the presence of calcium hydroxide.
