What is the best way to patinate metal?
Patination is the process of aging metal, think of rust on steel or the green spots on old copper. This is a natural process, but it can also be done intentionally to achieve a certain look.
There are different ways to patinate metal, depending on the type of metal and the effect you want to achieve.
Steel
If you want to age a steel object, such as a sword, axe or armor, you can do this in different ways.
The simplest way is to leave the object in the rain for a while and let it dry without wiping it off. You can also bury the item in wet soil for a while. The steel will rust, giving it an aged appearance. After the steel has rusted, you can clean it with some steel wool or very fine black sandpaper.
Another method to age steel is by using vinegar and salt.
Fill a spray bottle with vinegar and a generous amount of salt. Spray the mixture onto the steel object and let it soak for a few days. The more vinegar and salt solution you use and the longer you let it sit, the greater the effect. If you want a slower process so you have more control over the effect, you can dilute the solution with water. You can neutralize the rusting process with a solution of baking soda and water. Just like with the first method, you can remove some of the rust with steel wool or very fine black sandpaper.
Bronze, brass and copper
All three of these metals can be aged in the same way. All you need is vinegar and salt.
It's important to remember that this only works on items without a protective coating.
There are two different ways to patinate bronze/brass/copper with vinegar and salt.
The first way is to mix the vinegar and salt in a container that you can seal, such as a mason jar. You don't need a large amount, but enough to completely cover the bottom of the container.
Cover the object with the vinegar and salt mixture by applying it with a brush or spraying it on. After the item is completely covered with the mixture, you need to place it in the container and seal it. Turn the item approximately every hour until you achieve the desired effect. Rinse the objects with water and dry them.
If the patina becomes too dark, you can use steel wool or a small steel brush to soften the effect.
The other method is by soaking the items in the vinegar and salt mixture. Make sure the amount of vinegar you use is sufficient to completely cover the objects and let them soak for at least 45 minutes. Then place the items on a paper towel and let them air dry. By letting the items air dry, the patina continues to develop. Check the process every 15 to 30 minutes and once you have achieved the desired effect, you can rinse them with water and pat dry. If you want a very heavy patinated effect, you can also add some vinegar or salt while the items are on the paper towel.
Here too, you can soften the patina afterwards with steel wool or a small steel brush.
