- This product creates a chemical reaction with the surface of the metal to produce a dark, black antique finish on silver (sterling and fine silver).
- Avoid contact with skin and eyes.
- Always wear rubber gloves and safety glasses when using this product.
- Keep away from children and pets.
- Use in a well ventilated area and dispose of all application materials after use.

- Do not store near metals (such as tools). Metal that is in close proximity to a bottle of Silver Black will become corroded.
Now let's chat about how great it works on your metal!
Silver Blackener chemically oxidizes the surface of certain metals. We tried it out on a few of the metal blanks from the online shop.
The metals from left to right are: sterling silver, copper, nickel silver, gold fill, yellow brass, and antiqued brass.
The Silver Blackener was applied to each blank with a cotton swab. The blanks were rinsed and dried thoroughly and the top of each blank was polished with a Pro Polish pad.
Remember to work in a well-ventilated area and protect your work surface. We suggest working on a disposable paper plate. Rinse your piece thoroughly after blackening. We like to rinse first in baking soda and water to neutralize the acid (about 3 Tbsp soda to 1 cup water), then under running water. Dry the piece completely before tackling it with a Pro Polish pad. Water makes the pads sticky and will leave a film on the metal.
Notice in the picture above that the Silver Blackener does not darken the surface of the gold fill at all, but affects the metal underneath where it has been stamped. That's because the metal beneath gold fill is usually brass and the Silver Black works great on brass metal. It does affect blanks that are plated or antiqued, as shown on the antique brass blank.
This is probably the time to mention that oxidation with Silver Blackener must be removed through abrasion. That means buffing with a Pro Polish Pad or fine steel wool. If you throw a Silver Blackened blank in the tumbler, the oxidation will remain on the blank. The metal will stay nice and dark. It will be polished from the burnishing action of the tumbler, but the color will remain dark.
