This is a tough color to photograph, especially with my cheapie camera. Here goes. Vetrofond gunmetal, aha! promises implied. Metallic effect, neat reaction, something neat. What I got: another black. I don't have a good shop for coaxing the best out of colors, but I wanted something. On the left, Vetrofond gunmetal and on the right, CiM gunmetal. And a unique at that, supposed to not produce the effect as easily as with the standard. No matter how I look at it, the Vetro gunmetal is just black. It is not a failure of the camera but an effect of the glass. Heated gently for an extended time, black. This is the first bead. Maybe it reduces; this is the second bead. I put a drop of aurae on to check. Nothing. Does it do anything neat with ivory? Apparently not. Now we get into the CiM. I have had decent luck with this supposedly difficult color, probably since my HotHead reduces and burns cooler than pros' torches. I can see a sheen. It is even slightly evident in my lousy picture. Next is reduced as before. In order to distinguish between the 2 colors, I put a dot of ivory on the CiM beads. I didn't know I would get a reaction, but I like it. I din't get anything on the reduced bead other than this great reaction, but I will try it again. I have to do it this way since the ivory and CiM gunmetal bead did nothing.
Final analysis, I will buy any gunmetal except Vetrofond. It isn't doing anything for me.
