Glass Pure
Glass Pure is High-purity lime specifically tailored for float glass and clear container glass production. It is sourced from low-iron, high-calcium carbonate zones within the group company's deposit . Selective quarrying practices ensure consistently low contaminant levels in the raw material. After extraction, the lime undergoes washing, precision optical sorting and calibrated milling to achieve uniform particle distribution. Dedicated magnetic separation is applied to further lower iron content, meeting the stringent specifications required by glass manufacturers.
Benefits
Glass Pure offers a number of performance advantages that address key operational needs in glass manufacturing. Its consistently high purity improves glass yield rates by reducing impurities that interfere with the melting process. This cleaner input material helps glass producers maintain predictable furnace performance and achieve clearer finished products. The low iron content is particularly beneficial for applications where optical clarity and product appearance are essential.
- Enhances glass yield rates
- Lowers furnace energy needs
- Reduces rework and rejects
- Improves melt uniformity
- Consistent batch to batch quality
- Supports thin glass production
Together these benefits deliver greater efficiency across the melting and forming stages, helping manufacturers reduce energy usage, limit waste and optimise production runs. The consistent performance of Glass Pure ensures smoother operations and improved financial outcomes.
Uses
Glass Pure is designed for demanding applications across the glass and solar panel sectors. Its chemical purity and controlled particle size distribution make it ideal for float glass where clarity and surface quality are critical.
- Float glass manufacturing
- Clear container glass production
- Solar panel glass applications
- High clarity glass products requiring low iron input
- Glass batches that require uniform melt behaviour
- Processes where consistent particle size improves melting efficiency
These uses highlight the versatility of Glass Pure across modern glassmaking, enabling higher quality output while supporting advanced production requirements.
Production
Glass Pure is manufactured with strict control at every stage. The raw material originates from selected zones with calcium carbonate levels of at least 97.5 percent and iron oxide not exceeding 0.05 percent.

FAQs
How does Glass Pure improve furnace performance?
Its low impurities and consistent sizing reduce slag formation, improve thermal efficiency and support stable melting temperatures in glass furnaces.
Is Glass Pure suitable for thin or ultra-clear glass production?
Yes. The high CaCO₃ purity and minimal iron enable precise control of colour and clarity, making it ideal for thin float glass and premium container glass.
Can Glass Pure help reduce production downtime?
Absolutely. Uniform granulation and low dust contribute to cleaner handling, consistent feed rates and fewer interruptions in continuous melting operations.
