The paper presents a new methodology for research on gas generation property of materials used for sand forms and cores, models made of foamed polystyrene, protective layers, etc. In the form of an example, full analysis has been presented of gas generation property of a selected furan resin bonded sand, stating the course and kinetics of gas generation, their intensity in the time function, and in the heating temperature function. The description is of quantitative nature. The existence of peaks in gas generation intensity was observed at several temperature values. The results are well-correlated with the inclination to form surface defects of casts made in furnace resin bonded sands. This is the first study on gas generation kinetics in the mass heating temperature function.
