While they are a design staple of homes and businesses all over the world, most people don’t think much about how mirrors are made. This fascinating process involves chemical reactions to ensure that the mirror offers maximum clarity. Below are a few of the basics about how mirrors were made in the past and how they’re still constructed today. 

Polished Stone Mirrors

Obsidian is a type of rock that has been used since ancient times for tool and weapon-building, along with many other applications. When polished, obsidian also has a highly reflective surface, which led to its use in mirrors throughout the Inca and Aztec civilizations, as well as other cultures. Over time, other materials, such as gold and copper, were also polished and used to create looking glass. 

The Silvering Process

While similar methods for creating mirrors were used throughout history, it wasn’t until 1835 when the silvering process was invented. German inventor Justus von Liebig created a process that chemically reduced silver nitrate, which was then coated onto a pane of glass. Once dried, the silver nitrate creates a highly-reflective surface, which is why it’s still used today. This process made it possible to produce many mirrors at once, which caused them to be more accessible to the general population. In the past, mirrors were considered a luxury and only owned by the very wealthy. 

Along with the chemical process needed to create the reflective portion of the mirror, the glass used for backing must also be treated. It’s essential that this glass is exquisitely polished before the silver nitrate is applied for the best effect. If the glass has chips and defects, even minor ones, the mirror itself will become warped. While this might be interesting as a work of art, it won’t hold much value as a mirror.
