As you will see in the previous post - this is a bright yellow brass charm, with a hollow back.
I make an impression from the back with polymer clay (having tried the traditional method of covering the front in clay to make a mould - unsuccessfully)
I baked the mould - as in previous post and here is what I have got now
It is a yellow gold in proper outside daylight, but it's looking darker because of the dark light outside.
I didn't want an exact replica of the charm, I wanted mine to look as though it been dug up, knocked about a bit, and aged.
I rubbed it down with fine wet sandpaper to give it some natural wear and tear. Then I rubbed black acrylic paint all over it with my fingers and wiped off the surplus.
I used gold rub and buff all over it - and rubbed and buffed it!
Rubbed over some more black acrylic, and repeated the process.
I am pleased with the end result - it looks so much better in real life - it being gold rather than painted with gold paint. The raised parts shine and the recessed areas are dull and dark pitted.
I'll see what it looks like tomorrow and may do a bit more ageing.
This doesn't look like it's polymer clay at all which I am pleased about.
It's great to experiment.
