Hi, I actually did some experiments with low temp metals before I started working in a proper foundry. First, Atlas metals in Ohio is a decent source. You can get lead free low temp casting metals in 1/2 cubes (shipping these days is a drag). Someone on this thread suggested Britannia metal which as I recall is another name for Antimony. Tin is easy to melt. I used to do small impromptu casts by melting it in a cast iron pan on my little gas range in Italy. The combination of the two (tin and antimony) in the form of lead free pewter is preferred only because the Britannia metal imparts better flow to the metal, which makes for better casting. One more thing, for the sake of immediate satisfaction, I have been carving simple reliefs into soft fire brick and casting the metal. Quick, dirty, fun. Hope this helps.
