Check out my elements collection, mostly metals. The little cylinder of pure Tungsten (W), and the mini-ingot of Zinc (Zn) are new additions. I’m trying not to buy everything all at once from the wonderful website for Metallium Inc. based in Watertown, Massachusetts!
Admittedly, my collection has a long way to go. I don’t even have pieces of iron or chrome in there, for example. The hunt for those is on!
