- Limestone Design For Glass Batch
200 Glass Technology: European Journal of Glass Science and Technology Part A Volume 53 Number 5 October 2012 4. Particle size grading Chopinet at al(10) observed that the grain size of limestone was found to be an important parameter influencing the level of glass homogeneity. Limestone grains less than 200 μm were found to behave differ-

Soda and lime are added to glass batch in the form of soda ash (Na2CO3) and limestone (CaCO3). During heating, these two ingredients decompose to give off carbon dioxide (CO2), the resulting products being soda and lime.

To achieve a glass composition of 72 wt% SiO₂, 20 wt% Na₂O, and 8 wt% CaO, add approximately 0.1749 kg of soda ash (Na₂CO₃) to 190 lbm of quartz (SiO₂).Additionally, add approximately 0.027 kg of limestone (CaCO₃) to 190 lbm of quartz (SiO₂). By following these steps, the desired glass composition can be attained effectively.

The granulometric composition of batch for high-capacity glass production is analyzed. It is found that the narrow-fraction composition of sodium sulfate and feldspar in practice corresponds to the distribution of quartz sand particles, for which about 80% of the mass content falls into the 100 – 250 μm range. For carbonate and …
