Results of experiments on a physical model were compared with data obtained on a production forehearth for crystal glass operating at 2.5 tonnes/day. Good agreement was obtained. The method was then used to determine the optimum design of a forehearth producing 30 tonnes/day. The results of the temperature measurements indicate that a profile in the shape of a Cassinian half-oval is likely to produce better thermal homogeneity than a normal rectangular section.
