Cadmium Fish
Fish.
I cast this fish for the purpose of making a high-resolution 360 rotation image of it (click turntable icon or Spin link to see it). The yellow film covering some of the scales is either a thin layer of cadmium oxide, or possibly cadmium sulfide formed because I have used the same mold to cast sulfur fish before. Cadmium yellow (cadmium sulfide) is a classic painter's pigment so I hope that's what it is. Though toxic, it was widely used, and accounts for some of the bright, vibrant color in paintings of the impressionist period (Monet and all that). The fish shape comes from a cast iron corn bread mold, whose non-stick Teflon coating seems to have no problem with zinc, tin, cadmium, and similar metals with reasonably low melting points.

I chose this sample to represent its element in my Photographic Periodic Table Poster. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of.
