This is my piece of Nu Gold after being textured. I love it!
Its actually more gold than it looks but it picked up some pinkish stuff
from being in the pickling acid with the copper.
After a demonstration on how to use the jeweler's saw, we were turned loose on our metal samples. The metal seems thin, but its surprisingly difficult to saw. At least I don't have to fear taking off a hand, unlike my previous metal working days at ye old Worthington Industries. But, before we were ready to cut out our actual bracelet pieces we had some other steps to do. In order to make it workable, it had to be annealed.
That's right, they let us handle a gas blowtorch thingie (very technical term there) to heat the metal until it was red hot, then drop it in a crock pot of acid. Very exciting. After that, Jenny and I took steel texturing hammers to our pieces. She was working with copper, I had Nu Gold. (An brass alloy of copper and zinc I believe) I am quite pleased with how the texture turned out, though it was a long and rather noisy process to get there.
Next week we will glue our templates to the metal and cut out the links. And you can disregard the jewelry homework in the last post. My indecisiveness led to a last minute change of plans, so my links will now be tall rectangles of alternating copper and Nu Gold. Hopefully it doesn't look like poo when its all said and done.
