The passive analog technique is applied to cyclic glass pressing. Design details of an analog of a plunger‐glass‐mold system are given. The analog is used to provide results on plunger temperature profiles, heat contents, glass temperature gradients near the glass‐mold boundary, and rates of attainment of normal mold running temperature. These results are substantiated by practical pressing machine experience. The method is therefore of use in the assessment and design of glass‐pressing systems.
