摘要：
Measurement of gas pressures arising at the surface of cores by immersing test cores into molten metal as a function of time is proposed as an efficient method which reflects verY well the conditions prevailing in foundry practice. The factors relevant to gas evolution, namely, core length and diameter, type and amount of the binding agent used, moisture absorption, and type and thickness of surface films, have been investigated.
