How is soda-lime glass traditionally produced?

Soda-lime glass is traditionally produced through a process that involves heating a mixture of sand (silica), sodium carbonate (soda), and limestone. This combination is key to forming the glass, as each component plays a specific role in the process.

Silica, which is the primary ingredient, provides the glass with its basic structure and transparency. Sodium carbonate lowers the melting point of the silica, making it easier to work with during the manufacturing process. Limestone, on the other hand, helps to stabilize the mixture and improve the durability of the glass.

When these materials are heated together, they undergo a chemical reaction that allows them to melt and fuse, eventually forming a liquid glass that can be shaped and cooled into various forms. This method is a well-established and efficient way to create glass products, making option B the correct response.
