Default Aging Brass

When I made my Fortune Teller project, I wanted everything to look as old and antique as possible. That meant I had to age the parts I made out of shiny new brass. You may find the technique helpful for projects where you have new hardware and would like it to appear aged.

A simple 50/50 solution of vinegar and hydrogen peroxide achieves the aged look in about 5 minutes or less. It helps speed up the process if you heat the liquid in the microwave to about the boiling point before putting your brass pieces into the solution.

The acidic vinegar attacks the surface of the brass and the peroxide oxidizes it. When done, your solution will begin to take on a greenish color because of the copper leeched from the brass. The 50/50 solution can be saved and used again later on other projects.

Here are samples of the aged Fortune Teller side plate, and a comparison of two small brass hinges where one was aged, and one was not.

Great tip! Fun to experiment with how long it takes to get the color you want with all the different alloys.

The first thing I threw away on my way back from the Army was the can of Brasso.
Just saying,

When you heat up your solution in the microwave, do you leave the brass piece in the solution? That would speed up the process somewhat.
HAHAHA!

Just be careful mixing chemicals. Some chemicals can put off poison gas and at the very least can damage your lungs. Probably best not to do this in your wife's kitchen.
