Part 1 Manufacturing sodium carbonate
The coke and limestone are mixed in a kiln and ignited. While the kiln is in continuous operation, the incoming coke ignites automatically at the temperature of the kiln. The coke used is produced to very detailed specifications. It must be strong enough to withstand being crushed by the limestone when it is tipped into the kiln. It must also

How Cement Is Made
Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with ...

Limestone in Glassmaking: What You Need to Know. | Carmeuse
Limestone also helps to improve the handling and formability of the molten glass. In a pure silica melt, viscosity is high and this (alongside with high temperature) makes the glass difficult to shape, especially when it needs to hold a form, for example, in the production of glass containers. Limestone reduces the viscosity, making the liquid ...
