Float-glass furnaces, container-glass feeders, fibreglass bushings, special-glass tank components — glass manufacturing eats most refractories. Anderman supplies the fused silica, mullite, zirconia and alumina grades that handle glass-contact, gas-stream and structural service across the major glass-making routes.
Material selection driven by glass chemistry, temperature and the specific contact mechanism (immersed, gas-phase, refractory line). Not a generic refractory recommendation — the right grade for the right contact.
Tank-block-scale refractory components and large rollers, stirrers, plungers and spouts produced through partner manufacturing — sized for industrial glass production, not laboratory.
Direct experience supplying float-glass plants, container-glass furnaces and special-glass operations across UK and France. We know the wear mechanisms and the inspection cycles.
Float-glass tin-bath rollers, threshold components and tweel refractories run in reducing atmospheres at 600–1100 °C. Fused silica (ES99P) is widely specified for its near-zero expansion and non-wetting behaviour; AZS-style high-alumina-zirconia-silica refractories cover the bath roof and side walls. Anderman supplies the silica and alumina grades, plus zirconia stirrers used in optical-glass production.
Container-glass and tableware furnaces use mullite and high-alumina refractory shapes for feeder spouts, plungers, stirrers and bowl rings. Mullite tolerates the thermal cycling of forehearth conditioning; zirconia is specified for stirrers in contact with corrosive glass chemistries.
Fibreglass production runs platinum-rhodium bushings — supported by precision-machined alumina formers and substrates. Anderman supplies the alumina substrate grades and the high-temperature mullite components used in fibre and continuous-filament drawing.
Forehearth conditioning, metering plungers and gob-forming components run in direct glass contact at 1000–1300 °C. Specification balances glass chemistry, dimensional stability and thermal cycling — typically mullite for cost, alumina or zirconia where chemistry demands it.
