Heat transfer in glass‐forming operations depends on many factors, e.g. the properties of the glass, heat‐transfer coefficients at the glass/mold and mold/air interfaces, the characteristics of the mold material, and the glass/mold contact time. Using a computer model developed for one‐dimensional heat flow, the influences of these factors were calculated. The heat‐transfer parameters, which were analyzed individually, include e.g. the glass surface temperature, the peak inner mold surface temperature, the quantity of heat transferred from glass to mold during a steady‐state cycle, and the amplitude of mold surface temperature oscillation at steady state. Comments are given on the significance of the results.
