ABSTRACT OF THE DISCLOSURE An automatic cooling adjustment system for the forehearth of a glass furnace which enables the mini- mization of the amount of energy used in the fore- hearth. The system is utilized in a forehearth wherein a continually activated and adjustable cooling wind apparatus operates in conjunction with an electric or fuel fired heating system which con- trols or maintains the glass within a desired tem- perature range and at a predetermined temperature gradient range over the length of the forehearth. An automatic circuit is provided to adjust the amount of cooling wind and to maintain it at whatever level is required in order to minimize the opposing heating energy required. The system includes a timer which enables small automatic cooling wind adjustements during a first, relatively short time period and which enables temperature stabilization in the forehearth during a second, relatively long time period. The cycle of small adjustments is repeated as necessary to keep the heating system within pre-set energy limits.
