How to antique mirrors


Hi, I was wondering if anyone knew of the process of antiquing mirrors to give it that brown-black smoky look. Any leads would be appreciated.

Hey Rob,


The silvering (the chemical precipitation of silver) is bright and shine at first but will oxidize or tarnish if left unprotected. The early coatings used to protect the silver were a little hit or miss (the selection of the coating improved over time). So, the brown color is from the interaction between the coating, oxygen in the air, and the silver (and the precipitation method used) over time. Unless you have a lot of time to spare, say 50 years or so. You may need to work this problem backwards and treat the glass to get the color you are looking to get.

How do you "treat the glass" to get this antiqued look, smoky and with darkened sections.

Hi Rob

Hey! you ask the very question I was about to. We want to antique a mirror to put in our new bar here. Now the technique I recall being explained to me - but I have never tried - is to burn sulphur on the back side of the new mirror. I recall being told you lay the mirror down on say trestles - open air would be a good idea I expect - mirror side up. Underneath you place small dishes of sulphur (I don't know how far from the back of the mirror) and set them alight. Apparently the burning sulphur corrupts the backing. I am will to give it a go and will report my outcome. If you give it go, plse let us all know how it goes for you.

I have nothing to contribute to the process but I am interested in learning how it is done. So if anyone tries the sulphur solution, please post the results.

I have had great success with alcohol ink on the surface of mirrors to create a faux antique effect. It turned out great and the alcohol inks are easy to find, come in a lot of different colors, easy to work with, non toxic and are inexpensive.

Hi--just got on this site and want to share another site that provides info on how to antique (for grey, brown, clouds, blackened etc AND sells all the stuff to do it except for the paint thinner) They are called angelgilding and I'm going to order some of their stuff but want to try it out on small samples of mirror to get the technique down first. You can get small mirrors at Hobby Lobby for a few dollars.

Google angle gilding.

here is what they said about antiquing a mirror:

Mirror removers chemically dissolve mirroring chemicals and metallic leaf applied to glass. We have not tested them on other substrates.

2-Part Removers:
Silver Remover and Gold Remover are 2-part chemical solutions. Mixed together, they lose their effectiveness after about an hour. Mix equal amounts of "A" and "B". Rinse the glass after removing the silver to clean it completely.

Stripping Commercial Mirrors:
To strip a commercial mirror, use paint stripper to remove the paint before you remove the silver. Some paint strippers leave a waxy film on the glass. Remove the film by washing the exposed silver with our concentrated glass cleaner or acetone. Acetone [linked by editor to product info at Amazon] is available at most hardware stores.

Many commercial mirrors have a protective layer of copper over the silver. You can see the copper when you strip off the paint. Gold Remover dissolves both copper and silver.

Multi-layer Mirrors:
For multi-layer mirrors, such as galena over silver, dissolving the bottom layer usually causes the top layer to lift off. Use the remover designed to dissolve the bottom layer or use a multi-purpose remover, such as Gold Remover, to dissolve both layers at once.

You can physically remove a mirror coating by rubbing it with a paste of pumice and water. Our pumice will not scratch the glass. Apply it wet or dry with a cotton ball. Pumice offers another way to "antique" mirrors.

Silver Strip:
Chromic acid, also known as Silver Strip, is a "reportable substance" in any quantity under EPA rules. We do not carry it.

Blank squares indicate that the remover had little or no effect on the metal.
