I have had an old Yamaha Saxophone for over thirteen years. It was bought a bit rough to begin with, and after years of use and abuse, it was time to give this reliable instrument some love. I have a munchkin who has been learning to play, so I figured this would make a wonderful gift.
This instructable will show you how to do a chemical oxidation on brass, bronze, or any copper alloy for that matter.
Why do it?
In this case the chemical oxidation (sometimes called patina, redox, or distressing; depending on the application) serves two purposes: Give the sax a unique vibrant look and protect the brass from further erosion. The color I was going for was a charcoal gray to black. I believe I was successful!Materials
What you will need:
-Saxophone (or whatever brass/copper/metal you wish to use)
-Small Flat head Screwdriver
-Small Philips Screwdriver
-Fine grit sandpaper (400+)

Optional, but it will make your life a heck of a lot easier:

-accessory kit -baking soda
Total cost for materials (not including the sax, compressor, compressor parts and stuff I already had): A little over $80 bucks
