Base Pure
Base Pure is a high-calcium lime designed for colored container glass, glass wool insulation and general soda-lime glass production. Mined from designated low-iron zones of Group Company Deposit, it undergoes scalping, washing, precision sorting and calibrated milling for consistent sizing. Targeted magnetic separation ensures controlled Fe₂O₃ levels. Base Pure combines dependable chemical composition with engineered granularity, delivering effective fluxing action and stable batch performance across standard glass applications.
Benefits
Base Pure provides operational advantages across glass manufacturing lines that require reliable fluxing action and consistent melting behaviour. Its chemical composition offers dependable CaO performance which assists in lowering melting temperature and improving energy efficiency within the furnace. The controlled Fe₂O₃ level supports coloured container production by preventing unwanted shifts in tone and clarity.
- Reliable CaO fluxing action
- Stable melting and processing
- Suitable for coloured glasses
- Supports glass wool production
- Balanced particle size control
- Consistent batch to batch quality
Together these benefits help producers maintain high output quality, reduce process variation and support predictable operating performance across both container and insulation glass lines.
Uses
Base Pure is designed for a wide range of applications within the glass and solar glass industry. Its balanced composition and controlled granularity make it ideal for coloured container glass where batch stability and colour consistency are essential. The material also supports the production of glass wool insulation where uniform melting and dependable fluxing behaviour enable smooth fibre formation. In general soda lime glass manufacturing, the product serves as a reliable raw material that helps maintain melting efficiency and supports the production of clear and tinted glass forms.
- Coloured container glass production
- Glass wool insulation manufacture
- General soda lime glass applications
- Glass batches requiring stable melting behaviour
- Processes requiring controlled iron levels
- Applications that benefit from dependable particle size control
These uses highlight the versatility of Base Pure as a dependable input across multiple product categories within the broader glass sector.
Production
Base Pure is produced using controlled methods that ensure the final material meets strict industrial requirements. The chemical composition offers a calcium carbonate content of at least 95 percent with iron oxide levels not exceeding 0.08 percent.
