About Calcium Carbonate for Glass and Calcium

Calcium Carbonate for Glass & Calcium Limestone is an important component in glassmaking and is used as a stabilizer which improves the mechanical properties and physical appearance of the glass. Glass industry required high limestone. Iron and other colouring matter like carbon are regarded as objectionable. Shivish Microns LLP Limestone is ideal for the glass industry as it has a high purity with very low levels of undesirables and contaminants that would be detrimental to the glass making process. It has a very low Iron content with high Calcium content and with the added advantage of consistent Magnesium content typically. The Limestone that is produced can have both economic and environmental benefits to the glass producer. We currently produces high quality limestone for the manufacture of container glassware. Shivish Microns LLP Calcium Carbonate limestone powder is resulting perfect results in all glass applications, starting from commercial glass, recycling, container etc

High-Quality Calcium Carbonate for Industrial Applications

Calcium Carbonate is a key ingredient in glass manufacturing due to its high purity and consistent chemical composition. Its powder form allows for easy blending in various processes, while its low moisture content (0.2% max) and fine particle sizes ensure uniform dispersion. Our product's stability up to its decomposition temperature makes it an ideal material for demanding industrial environments.

Reliable Packaging and Shelf Life

Packaged securely in HDPE bags (25 kg or 50 kg), this Calcium Carbonate powder maintains its quality during storage and transport. With a shelf life of two years from the date of manufacture, and ISO 9001:2015 certification, customers are assured of both product safety and compliance with international standards.

FAQ's of Calcium Carbonate for Glass and Calcium:

Q: How is Calcium Carbonate used in glass manufacturing?

A: Calcium Carbonate serves as a raw material to enhance strength, improve clarity, and reduce the melting point in glass production. Its high chemical purity ensures that the glass maintains optimal physical and structural properties.

Q: What particle sizes are available, and how does mesh size affect application?

A: We offer Calcium Carbonate in 48, 100, 200, and 325 mesh. Finer mesh ensures better dispersion and is commonly used in applications requiring high-quality, homogenous final products, such as specialty glass and fine chemical processes.

Q: Where can this Calcium Carbonate be used apart from glass making?

A: Apart from glass manufacturing, it can be used as a calcium source in chemical processes, or as a supplement in certain industrial and agricultural formulations. Its high purity and low toxicity make it suitable for a variety of applications.

Q: What benefits does your Calcium Carbonate offer to manufacturers and traders?

A: Manufacturers and traders benefit from its high chemical stability, consistent particle size, negligible water absorption, and reliable packaging, all of which contribute to efficient processing and quality end products.

Q: Which packaging options are provided for Calcium Carbonate, and are custom sizes available?

A: We supply the product in 25 kg or 50 kg HDPE bags for safety and convenience. Custom packaging can be arranged according to specific buyer requirements to ensure flexibility in logistics.

Q: How should Calcium Carbonate be stored to maintain its properties?

A: Store the product in a dry area, away from moisture and acidic substances, to preserve its low moisture content and chemical stability throughout its two-year shelf life.
