Hi both, thanks for the responses.
I think if your 'gold' tarnished it wasn't pure gold. Since I've started looking into this, I've discovered that some gold leaf is actually gold on base (how they manage this on that super thin leaf, I've no idea).
I've now experimented with a small batch, and so far so good....but time will tell.
Of course this would be so much better in transparent glycerin melt and pour.....just don't think I can bring myself to do it. I've recently been given a few samples of some of that; within hours of taking it out of the plastic, it was all wet and slimy; without even using it. Is that normal??
I'll report back in a week or two, as to whether the gold stays gold, or turns black :cry:
