Glass batch chemistry with high-purity aragonite

Published chemistry and formulation guidance for modern glass.

Summary

Calcium carbonate is a common CaO source in glass batch formulations. Purity and particle-size distribution influence batch behavior and finished-glass requirements. Natural oolitic aragonite supplies calcium carbonate for container, flat, solar, fiberglass and specialty glass formulations.

Why aragonite in glass batches

Batch chemistry

CaCO₃ content, CaO contribution and impurity limits align with the complete formulation.

Particle distribution

The GL-CAL grade is sized below 0.1 mm for glass-batch mixing and handling.

Material form

Orthorhombic aragonite provides a distinct calcium-carbonate mineral form.

Processing

AragoCor oolitic aragonite is supplied without a calcination step.
