Are My Custom Mirrors at Risk of Developing Black or Brown Spots?

When you’ve put the time and money into placing custom mirrors in your home, the last thing you want is for black or brown spots to develop.


Custom mirrors are an investment and once they’re in your home, they become an important design element.  That’s not something you want to see ruined by deterioration and disfigured by contingencies like condensation.

You’re reading this because you’re asking yourself, “Are my custom mirrors at risk of developing black or brown spots?”.  We’re going to answer that question.  But first, we’re going to talk a little bit about the historical development of the mirror and how processes to produce them have changed, with time.

Back In the Day

You may not be aware, but the mirror has a long and glorious history.  Still water was the first mirror humans ever used.  We all know the story of Narcissus and how he saw himself in a pool of water and fell in love – with himself.

But after that, humans crafted mirrors from all manner of materials.  From the bronze used by the Ancient Egyptians to the obsidian used by Anatolians in what is now Turkey.

The surfaces of early materials used to create mirrors were, by necessity, flat and highly polished to offer as clear a reflection as possible.  But in the 1st Century of the Common Era in Sidon, Lebanon, the first glass mirror employing a metal backing was produced.  It was this mirror which became the precursor to the modern mirror.

Justus von Liebig created the first silver-backed mirror in Germany, in 1835.  When people worry about black and brown spots, it’s this type of mirror they’re thinking of.

Vintage Mirrors

Visiting flea markets and antique shops to find one-of-a-kind items is an obsession for many of us.  But when we buy a vintage mirror, we’re probably buying one produced via an imperfect manufacturing process.

And that’s where those black and brown spots come from.  But why?

Simply, what the mirrors were backed with was insufficiently durable to prevent the incursion of water from condensation and other fluids seeping between the glass and backing used to create a reflective surface.

Mirrors are no longer produced by this process, so the likelihood of your custom mirrors developing black and brown spots is minimal.  While it’s still possible (especially where low quality mirrors are concerned), it’s not as likely as it may have been back in Justus von Liebig’s day.

Custom Mirrors Today

At Accurate Glass and Mirror, we love working with this reflective material.  Mirrors have myriad uses in the home and are comfortable in every room.

The mirror has come a long way since the Sidonites invented the precursor to the mirrors we look at ourselves in every day.  Modern processes have made mirror backings infinitely more durable and long lasting.

Your custom mirrors are highly unlikely to develop black or brown spots, especially if you’ve obtained them from AGM.
