How to Make Brass Black

Brass is a beautiful metal, but if you’re looking for something darker or more rustic, consider blackening your brass. There are several blackening brass methods, including chemical and heat treatments. In this article, we’ll discuss the best ways to make your brass look like it has been blackened.

Chemical Treatments

Chemical treatment is one of the most popular methods for blackening brass. This method involves dipping the brass into a solution of potassium nitrate, sodium hydroxide, or other similar chemicals. The chemicals react with the surface of the brass and cause it to oxidize, resulting in a darker colour. While this method is relatively simple and inexpensive, it can be dangerous because of the toxic chemicals involved in the process.

Heat Treatments

Another method for blackening brass is by using heat treatments. This technique involves heating the brass until it’s at a high enough temperature that oxidation occurs on its surface. When applying this method, be cautious, as high temperatures can cause damage to the metal itself or any nearby materials. After heating your brass, allow it to cool down before handling it, so you don’t burn yourself!

Painting or Powder Coating

Another option for making your brass look like it has been blackened is by painting or powder coating it. This method first involves preparing the surface of your brass by cleaning and sanding off any dirt or debris on its surface. Once cleaned and prepped, you can apply paint or powder coating to achieve an even black finish on your brass piece. Be sure to follow all manufacturer instructions when applying either paint or powder coating to get desired results!


Blackening your brass can add an exciting touch to any project you might have in mind. Whether you choose to use chemical treatments, heat treatments, painting or powder coating, there are many options available for making your brass look like it has been blackened! Regardless of your choice, always take precautionary measures, such as wearing protective gear when working with potentially hazardous materials and following manufacturer instructions when using paints/powder coatings. With these tips in mind, you should be fine achieving successful results when making your blackened pieces from home!
