Origin

The phrase alludes to a chemical test to prove the pureness of gold. This test was developed in the late 18th century and used nitric acid, which dissolve other metals more readily than gold. So the amount of metal dissolved would prove the pureness of the gold. The figurative use started around the mid 19th century, with the earliest print reference being in the Wisconsin paper "The Columbia Reporter" in November 1845.
