Desilvering – What To Do About Black Edges On Mirrors

When you look into your mirror, the only thing you want to see is your beautiful face and smile beaming back at you. However, time can take its toll on your mirror. This is especially true when they are installed in moisture-rich areas, such as the bathroom. 

As time goes by, ugly dark spots and black edges can appear. What causes this dreadful damage? Mirror desilvering. Here’s everything you need to know about desilvering and how you can quickly and inexpensively take care of the trouble with a little help from a custom frame from MirrorChic.

What is Mirror Desilvering? 

The reason your mirror sparkles, shines and reflects is the silver coating behind the glass. The silver is chemically bonded to the backing when it is manufactured, but that bond can naturally break down over time. However, time isn’t the only reason.

When mirrors are exposed to excess moisture, water can get between the layer of silver and the backing. This causes the bond to break and the silvering to chip off behind the glass. This leaves your mirror with unsightly dark spots or black edges where the silver has fallen away.

What Causes Mirror Desilvering? 

The most common cause of desilvering is excess moisture. Bathroom mirrors are especially vulnerable to black edges appearing over time. Whenever you wash your hands, take a hot shower, soak in the tub, or splash around, your mirror absorbs the moisture that is thrown into the air.

The effects of repeated exposure to steam over the years eventually causes it to desilver. Therefore it is recommended to limit splashing, misting and fogging as much as possible to protect not only your mirror but also the other fixtures in your bathroom.

Mirror Repair – How to Repair Mirror Desilvering

If you’re reading this article, you are probably wondering how to fix or cover up those ugly black edges on your mirror. There are a few options to choose from. 

The most obvious choice is to simply replace the mirror entirely. Of course, replacement is no simple task. It is a lot of work and time to take down an old mirror and a lot of expense to purchase and hang a new one. There is another way; custom mirror frames. 

Can I Resilver A Mirror Myself?

You can resilver a mirror yourself, the process itself is not difficult. Most do not consider resilvering a DIY project because the chemicals involved are both costly and highly toxic.

Make sure to acquire and wear safety glasses, gloves and a chemical breathing mask and read all usage and disposal instructions that will come with the chemicals.

How Much Does It Cost To Have A Mirror Resilvered?

Resilvering is possible, but it is increasingly hard to find service. Resilvering is time-intensive and costly to perform. Taking it down and transporting (or shipping) it to a repair shop can lead to even more damage. As a result, there are few places that offer resilvering services, since you are often much better off replacing. This option is only really recommended if you simply cannot part with your old mirror, such as with a family heirloom or beloved antique. 

Why worry about spending time and money replacing the mirror or the silvering when you can simply cover it up? A custom frame can be made to fit over the damage, as desilvering usually occurs around the outer edges of the mirror.
