We are asked repeatedly where to find "antiqued" or "manipulated" (made to look antique) mirror plate for design projects or to refit antique frames. Until recently, we had two tried sources, one in New Orleans and one in Charleston. Because this antiquing method is done during a hand-silvering process, the cost of these plates is high (relative to the market value of silver).
Modern mirror is electroplated-a process that fuses some alloy to the glass, which is then back coated for protection and preservation. The reflection is very sharp, almost harsh, especially when paired with an antique frame that has mellowed with time. When we buy empty antique frames, we often refit them with antiqued or manipulated mirror for a more compatible look.
Recently, I received a call from a man claiming that he was patenting a solution that would make electroplated mirror look old. He convinced me to buy a quart, practically guaranteeing my pleasure. The quart of etching solution arrived with a long list of supplies needed (including protective clothing) and instructions that were somewhat intimidating. It took me some time to gather the supplies and the courage to attempt the project.
The first attempt was hugely successful, which inspired me to try it again and again, fine-tuning my technique each time. Gradually, my protective clothing has been reduced to thick rubber gloves (chemically resistant) and goggles. I perform the manipulation in the workroom of our shop. For liability reasons, I'm not encouraging anyone to ignore the instructions regarding protection of eyes, hands and lungs. I merely wish to relate how simple this process is.
Basic supplies needed:
1. Klean-Strip metal stripper (in the red can) found at Lowe's or Wal-Mart
2. Foam brush(es)
3. Etching solution
4. Spray bottle (I originally used an empty 409 bottle but later bought a heavier "chemically resistant" plastic bottle that had a more sensitive spray adjustment)
5. Black enamel spray or clear satin spray lacquer to protect the back of the mirror after etching (I use Deft satin but I'd like to experiment with black and even terra cotta in future)
6. Newspaper and a working sink or hose
Directions:
Don protective gear. Place the mirror face down on newspaper (you are looking at the back of the mirror). Pour the metal stripper (well-shaken) in a 2" thick line across the top (it is best to work in temperatures above 50 degrees). Use a foam brush to spread the stripper down (in one direction). Be generous with the stripper so that you have enough to spread to the bottom. Wait a few minutes and you'll see the protective back coating bubbling. If an area does not bubble, apply some more stripper with the same brush. I use the brush to slide the disengaged globs of metal paint off the glass onto the newspaper. Don't worry if some small areas stick. Wash the back of the plate with a hose or in a sink (wearing your gloves until all stripper is removed). Dispose of the brush and the globby newspaper and allow the plate to dry.
In the spray bottle, mix the antiquing solution with water. I've used a 1-1 ratio to date and have been pleased. I have not tried heating the solution per instructions. If you desire large dots, adjust the nozzle to course spray. If you want small dots, use fine spray. You might want to check the spray pattern against a cardboard box or more newspaper before you spray the glass. The solution has a bit of a rotten egg smell, nothing that a squirt of air freshener can't eliminate.
Prop the glass vertically against something disposable (like cardboard or plywood) and spray a light coat. You can check the front of the mirror in about 20 minutes to determine if the etching is heavy enough. You can respray if desired.
When the plate is dry, spray on the protective coating.
I'm including some pictures of my samples. Unfortunately, the flash makes the dark spots look white. Note: If you were planning to glue the antiqued mirror to a wall or piece of furniture, I am not at all sure about the chemistry between the glue and the sealed etched mirror. Perhaps, over time, a shadow of the glue will show through. You will just have to test.
