oooo, this one turned out mighty fine. Been playing around with patinas. This PMC tube bead turned the most amazing rainbowy colour, dominately copper with touches of blue and green. The trick is to dip into liver of sulphur for a few seconds several times, each time dipping the bead a little less into the solution so that the colours varigate. So... some parts of the bead are subjected to more patina-ing (hehehe...um, what can I tell ya? I like to make up words),... the most time in the solution, the darker it is. I definitely want to explore this some more...
