| Museum-grade sample. In early 2004 Max Whitby and I started selling individual element samples identical or similar to the samples we use in the museum displays we build. These are top-quality samples presented in attractive forms appropriate to the particular element. They are for sale from Max's website and also on eBay where you will find an ever-changing selection of samples (click the link to see the current listings). This sample shows the appearance of the metal when dropped into a bucket of water. The metal is taken to just barely above its melting point, then poured in from close to the water surface, a potentially dangerous operation particularly in the case of aluminum (which can form hydrogen gas that may explode). If the temperature is too high the metal fragments into an almost powder form, so it is a delicate matter to get just the right conditions for the formation of smooth shapes like this. 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.
