Abstract
Samples of rosin, abietic acid and pitch may be made to flow at temperatures as low as 20°C at low pressures and conveniently short periods of time, sufficient for fluidity determinations. Such a method as this one was devised in the hope of finding a much better control instrument for such materials. No evidence of plasticity was observed. The fluidity was found to be independent of the dimensions of the apparatus used. In the pressure range from 130 to 1800 g per cm2 no effect of change of pressure upon the fluidity was detected. A study of the effect of changes in pressure upon the flow of plastic materials is now being made.Keywords
