title: [Resistance to pressure of amalgam relative to the pressure of plugging and the alloy-mercury ratio].
abstract: The resistance to pressure was tested in 320 Amalgam samples of alloy-mercury in relations of 4:3, 5:5, 5:6 and 5:7 under packing pressures of 2, 5, 10 and 15 N/mm2. These tests were made with a commonly-used and a copper-rich alloy. Very dry mixtures, which condense under low packing pressures, show low pressure resistance.
