Abstract
This is a study of the effect of condensation pressure upon crushing strength and mercury content at various amalgams, and of the relation between crushing strength and mercury content. The results are presented in Tables 1 and 2, and in Figures 1, 2, and 3. The experiments show that and increase of the condensation pressure from 0.8 to 9.4 kg/mm2 results in a continued increase of the crushing strength and a reduction of the mercury content (Figures 1 and 2). The experiments also show (Figure 3) that a reduction of the mercury content of the amalgams below 50% will result in an increase of the crushing strength from 40 to 75 kg/cm2/%.
