Melt to fuse
Glass is a mixture of different minerals, mostly quartz. So far, so good. But how can these components be transformed into a delicate material such as glass? This is achieved by melting. Experts call this "melting the batch".
In practical application, this works as follows: The melting furnace heats the raw material to a temperature of around 1,200 degrees Celsius. That is the temperature where the components of the raw material – the batch – such as silicon dioxide, sodium oxide and/or calcium oxide merge or rather mix to form a unit. They become a glass mass.
The term "melting the batch" is not only used for glassmaking, though. Experts use generally use this term to describe the process where a mixture of different components is melted to form a unit. One possible example is the production of acrylic glass.
