GL-CAL — Glass batch feed
High-purity, low-iron carbonate for container and specialty glass.
See GL-CAL specificationsThe problem you’re solving
Batch houses need a CaO source with tightly controlled iron so colour and redox stay predictable batch to batch.
Why this material fits
- Iron oxide ≤ 0.04% on representative analysis
- Fine sizing (< 0.1 mm) for batch-free time
- Consistent single-source marine feedstock
Available particle sizes
- < 0.1 mm fine
- Custom
Packaging options
- Bulk

No kiln. No calcination. Less processing than conventional calcined lime.
Frequently asked questions
How does aragonite behave against limestone in the batch?
The glass batch chemistry brief covers CaO availability, batch-free time and iron control considerations for container and flat glass batches. Request it from the document library.
Can you supply to a target distribution?
Yes — custom-sized material is produced to a target distribution. Send the specification with your enquiry.
