Glass Industry
Iron content you can trust batch after batch, a consistent grading into the furnace, and refractory materials that stand up to the melt.
Low iron, documented
High purity limestone at max 200 ppm Fe₂O₃, plus fine fillers developed for glass batch.
Batch consistency
Feldspar, soda ash and quartz supplied to a tight, repeatable grading and chemistry.
Refractory contact
Fused silica, zircon, chromite and alumina for furnace and forehearth service.
Full documentation
Certificates that support your batch calculation and your customer’s audit.
8 grades for glass industry

put in a batch model
A glass batch is a calculation. It only works if the incoming material matches its certificate, every load.
- Analysis you can rely on. We agree the analysis regime with the producer and supply the certificates that feed your batch model.
- Samples with data. Full technical data with every sample — not just a bag and a phone number.
- Scale-up support. Once qualified, we lock in the supply route, packaging and stock level before you launch.
- Second source planning. Where it matters, we help you qualify an alternate grade in advance rather than during a shortage.
