Thing A Week 4: Borax Red Jewlery

I have occasionally in my goofing around with torch and flux turned a piece of copper bright red. I had no idea how I had accomplished it, and chocked it up to a fluke of chemistry.  The color however was gorgeous, and I was sad I couldn’t recreate it….that was until I stumbled upon the hidden knowledge of the Borax Red Patina.

It’s super simple, you just take some water, dissolve as much Borax (20 mule team Borax from the store works just fine), heat your copper up till its bright red, and dunk it in the water.  The finish is very rugged and wont wear off, but it is heat sensitive, so make sure you only do cold forming after the treatment, if you need to solder anything on its going to be a little tricky.

 

I played around with the technique for a while and found it rather fun to just make the copper red, you can lightly polish it after to bring out the redness and make it more interesting.

I ended up making an earring and pendant set.  Its all pretty rough, as I was just sort of playing around, but I am glad I figured out the technique and will use it again in the future.
