Interesting melted shape of copper. Description supplied by the source: This is a good sample of several possible appearances for copper- the top is wire-brushed, if memory serves, the bottom is the as-cast surface that was up against the also-copper crucible, and the side shows the internal crystalline structure. I melted this particular piece from 4N5 pure melt stock in a shallow crucible: It's just a nice looking sample.
