Introduction:
Glass Feeder Expendables is the refractory parts used in the gob forming process. They are ‘expendable’ because they are changed frequently during the life of furnace depending upon requirements of the forming operation.
As the final link between the glass conditioning and forming processes, feeder expendables have immense influence on the success or failure of the entire forming operation. They must be able to resist the corrosion from molten glass at the same time as being able to withstand the thermal shock of immersion in molten glass.
Our refractory compositions are slip cast not chemically bonded or pressed, ensuring a homogeneous ceramic body with a densely packed surface texture. Slip cast into plaster moulds, dried in humidity controlled drying chambers and sintered at high temperatures, Fireramo feeder expendable refractories are renowned for their consistency, reliability and longevity.

Features:. 
Major phases comprise corundum and mullite in a matrix of zircon and secondary mullite.
• Excellent corrosion resistance and resistance to thermal shock.
• Recommended for all feeder expendable applications.
