  Fish.
I cast this fish for the purpose of making a high-resolution 360 rotation image of it (click turntable icon to see it). The yellow film covering some of the scales is cadmium oxide, which I left on because cadmium yellow is a classic painter's pigment. 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.
