How to Age Brass Metal
- 1). Pour 1 cup of vinegar into a plastic bowl. Add 1 tbsp. salt to the vinegar and stir thoroughly with a plastic spoon.
- 2). Place the brass in the bowl and soak it in the vinegar mixture for about five minutes.
- 3). Remove the brass from the bowl and pat the metal dry with paper towels.
- 4). Place the brass on a cookie sheet and place it in an oven preheated to 450 degrees Fahrenheit. Watch the brass as it heats. It will age, browning due to the heat. Remove the brass from the oven when it reaches the desired tint and allow the metal to cool completely.
- 1). Create the vinegar solution, consisting of 1 cup of vinegar with 1 tbsp. of salt, in a plastic bowl.
- 2). Submerge the brass in the vinegar solution for one hour.
- 3). Remove the brass from the vinegar and place it on a dark baking sheet. Place the baking sheet in an oven preheated to 450 degrees Fahrenheit. Heat the brass in the oven for 20 minutes.
- 4). Remove the brass from the oven and return it to the vinegar mixture. The solution will create a green patina on the brass as it soaks. Watch for the desired effect and then remove the brass from the mix. A light patina takes less than five minutes soaking time in the solution.
- 5). Shake off the vinegar from the brass and allow it to air dry. Polish the metal with #0000 steel wool after drying to create the look of a semigloss surface with green tint.
