industrial tile

I have been china painting this tile (on and off) for the last couple of months. It looks like the bottom to some sort of scientific scale, and is a beautiful piece of porcelain. I have been firing it over and over, adding a little more information every time, and making my lines nice and thick. I have a few more blanks to work with - these should be a nice addition to the cut paper pieces.
