Another session with metal and acid.

These are more for testing purposes as I was still figuring out how to work with acid and stencil.  The one on the right, the skull one, is more simplistic except for the teeth, that took some work.  The left one was more complex job, as there were lot more of the nooks and crannies to cut around (as well as adding some tapes in some negative areas).  Then there was the task of determining how much acid to pour to get the desired effects; the first time it matted out the sheen from the metal but retained the grey color, then adding more in the concentrated areas brought out the rusty brown color.  I just let the liquid flow around as it pleased occasionally dabbing off some to prevent it from going too far, and I was pretty surprised at how it turned out.  It kind of looks like a halo of smoke rising around the skull and the mask, as if it is being possessed by an ominous spectre.  I will have video of the process coming soon so you can see for yourself.

As for the title, well, doesn’t the picture say it all?  😉
