Oh, and... I redid the pick guard. I wasn't happy with the first try and when I added some more ammonium (hoped for more colour), it just ATE right through the copper leaf. Bummer.
So re-plated it and added 5 layers of leaf this time.

Also, I had the genius idea (hahaha lol!) to do a test piece first. (Lightbulb goes on)

So here is some plastic covered with just one layer of copper.
Salt and ammonia on the left, salt and vinegar on the right.

After an hour, it looked amazing (even though it ate through the one layer of copper easily).

So I actually gave up on my hope of getting some blue or green colors. I left it like this over night, hoping it would dry out and I could maybe brush on a little ink (it's cheating, I know! ).

After I woke up in the morning, NOTHING had happened to it! It still wasn't dry! So I took it out, threw it on the coffee table, forgetting about it until 2 hours later.
Went into the living room, and found this!

Fiiiiinally! I really love how it turned out! This evening, I'll be sealing it with spray lacquer. I hope it will keep its amazing look!
