Tin allowed for the much more complex shapes cast in closed moulds of the Bronze Age. Arsenical bronze objects appear first in the Near East where arsenic is commonly found in association with copper ore, but the health risks were quickly realized and the quest for sources of the much less hazardous tin ores began early in the Bronze Age. This created the demand for rare tin metal and formed a trade network that linked the distant sources of tin to the markets of Bronze Age cultures. Cassiterite (SnO), the tin oxide form of tin, was most likely the original source
Fish and Tin and Copper and Dancers, was set to the song Fish and Tin and Copper. The group had originally performed it as a demonstration dance at the opening ceremony of Lowender Peran in 1997. The chorus of the song inspired the use of traditional steps and patterns to represent these Cornish industries, including steps from the Newlyn Fisherman's Reel, followed by a chain (swimming fish), then the turning of wheels and cogs of the mines. Fish and Tin and Copper Fish and Tin and Copper is a traditional folk song/ballad associated with Cornwall, and dealing with the legend of the devil ("Old Nick")
