The fluid properties of 40 high volatile bituminous coals have been studied by Gieseler plastometry, under both ASTM (3 K min-1) and isothermal conditions. The Gieseler curves obtained have been analysed with regard to 52 physical, petrographic, and chemical measurements made upon splits of these coals. A number of predictive regressions are developed, including equations predicting ln(maximum fluidity) with R2 values of 0.927 (3 K min-1 ramp) and 0.935 (isothermal at 420 °C). The significance of the best predictors, and of the signs of their coefficients, is discussed.
