I imagine there’s a group of economic historians somewhere in this world that are currently in a tizzy.It turns out that figuring out the age of a metal is hard; there aren’t many scientific options for dating many archaeological artifacts made of copper, iron, tin, gold or lead, according to Antonio Doménech-Carbó, an analytical chemist at the University of Valencia, in Spain.By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.Though still heavily used, relative dating is now augmented by several modern dating techniques.Unfortunately for this inflation controversy, different silver isotopes are really hard to tell apart analytically. Instead researchers could try comparing isotopes of lead, which is another element present in silver ores and is thus is also found–in trace amounts–in silver coins.Except unfortunately lead isotope ratios are quite similar in Europe and the Americas—a tad too similar to conclusively distinguish the provenance of coins through lead isotopes alone.tempted to look at isotope ratios of copper which was added to the silver coins to improve their hardness.But scientists have to be wary of drawing too many conclusions from copper isotope analysis of silver coins because the copper might not have originated from the same place that the silver was mined.

For example, “lead was produced for fishing nets, anchors and sling bullets, fastening iron clamps in the walls of buildings, water pipes, jewelry and cult figures,” Doménech-Carbó notes.

Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content.

Carbon-14, or radiocarbon, is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.

All this inspired me to track down the song This Corrosion, by the English band Sisters of Mercy, who are not precisely a metal band per se, but are definitely a fascinating artifact from the 1980s music scene.

Love-hungry teenagers and archaeologists agree: dating is hard.
