Silvering & Mirror Making
A Precious Metal In-Your-Face • Not many people realize it, but precious metals are common components inside many industrial products. • Palladium is used in catalytic convertors • Gold is used in high-quality HDMI and component cables • Silver paste is used in solar panels and circuit boards • However, one household item puts a precious metal front-and-center: mirrors
The Evolution of Mirrors Mirrors have been made out of many materials over the years. The trajectory of their evolution, looks something like this: Polished Stone (obsidian, volcanic rock, etc.) Glass Panes with Metal Backing Bronze, Copper, Tin, and other metals Aluminum & Glass “Silvered” Glass
The Silvering Process • Silvering was invented by a German chemist named Justus von Liebig in 1835. • In silvering, a thin layer of silver is deposited onto a glass surface via a chemical reduction of silver nitrate. • The layer of silver produces a flawless reflection, while the glass protects the silver from corrosion, oxidation, and scratches. • Of all the metals used in mirror making, silver has the best surface reflectivity in the visible spectrum – meaning it makes the very best mirrors.
Silvering and Modern Mirror Making Silvering is still used to make modern day mirrors, but the process doesn’t always use silver. • The glass on household mirrors can distort reflections, so aluminum (which also has a very high surface reflectivity) is silvered onto the outside of a glass surface for precisionmirrors. • Unlike silver, aluminum doesn’t need the protection of the glass, so it can be exposed to the elements and still produce clear reflections. • Gold is also silvered onto infrared instruments to create mirrors that reflect infrared light without oxidizing or corroding.
Silver Content in Mirrors • Silvering is a useful and cost effective industrial process because it deposits exactly enough silver to produce a reflection – no more. • Even though your household or antique mirrors may contain silver, it’s not enough to expect a huge payout from a precious metal recycler.
