| 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 cast ball is designed to show what the surface of the metal looks like when hammered: By comparing with similar hammered balls of other metals an idea of the hardness and working characteristics of the metal is given. (We use approximately the same hammering force on each ball, so lead will show much deeper hammer marks than zinc, for example.) 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.
