I also made a Mexican scull type pedant. Id like to find a good resist for etching but I kind of like the drawn on effect.
The oxidisation of the copper was done with egg fumes.
I assumed that because an off egg stinks more than an fresh one that it would have more sulphur thus speeding up the oxidation process.
I don't know if this is the case.
But its the first time I've smelt an off egg, and hopefully the last... it smells like death!
Here is the copper after a whole night in the fumes of the egg:
And here are a few images from my house:
Spring is here!
It works but after you turn it on it takes a few minutes to 'warm up'
Good night blog!
