Steel bolts that apply pressure to the outside face of the constructed furnace refractory structures to act against internal outward pressure.
Steel members that brace the furnace refractory structure.
The section of sidewall between the soldier block and the crown skewback.

The working life of a tank furnace from the start of a new furnace construction to the shut-down of the furnace.
The steelwork case supporting the forehearth sub-structure refractory.
The sub-structure part of the forehearth that carries the molten glass from the distributor (working end) of the furnace to the spout.
CHECKERS (OR PACKINGS)
The refractory pieces installed in the regenerator chamber for the purpose of heat recovery.
The part of the forehearth after the cooling zone(s) where the glass is brought to the required working temperature.
CONTINUOUS TANK FURNACE
A furnace which produces glass on a continuous basis in which the level of the glass remains relatively constant due to the batch being fed continuously into the furnace, therefore, replacing the glass withdrawn.
The cool-down of a furnace from working temperature to ambient temperature under controlled conditions.
The part of a forehearth adjacent to the refiner (or distributor/working end) and before the conditioning zone.
A tank furnace with parallel pairs of ports for fuel and air positioned along the length of the melting end with the burner flames travelling across the width of the glass bath and at right angles to the direction of glass flow.
The roof part of selected furnace areas.
Broken glass that is added to the batch for re-melting.
DISTRIBUTOR (REFINER OR WORKING END)
A section of the Tank Furnace to which glass is delivered from the throat and then directed to the forehearths.
A small vestibule section of the furnace at the batch charging position into which the batch is discharged into the furnace melting end.
An auxiliary method of adding heat to the glass of a fossil fuel fired tank furnace, by passing an electric current through the molten glass.
A tank furnace with the ports situated in the back wall of the melting end and the burner flames travelling in the direction of glass flow.
A tank furnace with the ports for fuel and air situated in the back wall of the melting end.
FACTORY CULLET (OR IN-HOUSE/DOMESTIC)
Cullet that is obtained from the glass making process within the factory.
A mechanical piece of equipment for the function of delivering glass gobs to the forming machine.
The opening in the Refiner (Distributor or Working end) sub-structure wall to receive the channel of the forehearth leading to the feeder.
An opening in the Refiner (Distributor or Working end) sub-structure wall through which glass flows into the forehearth and towards the feeder.
FLUX-LINE (OR METAL-LINE)
The level of the molten glass in the furnace.
The casting cavity in a fused cast Alumina/Zirconia, Silica refractory block.
A section of the Tank Furnace leading from the Refiner (Distributor or Working End) from which glass is conditioned and directed to the feeder forming process.
Cullet produced and obtained from an outside source.
An organic product of fusion that has cooled to a rigid condition without crystallising.
A general term used when describing glass bottles and jars.
An amount of hot glass delivered to the forming machine by the Feeder.
