Ravenesque, you put Iris & Arke right up near the face of the torch & run it through the ends of the candles? I've never done that with any of my silver glass, except with an oxidizing flame of course.
Here is another set that I did the same way as the rounds, you can see that some of them went copper & someo of them wouldn't go past gold. I feel like you, I don't want it to beat me! LOL
