etymonline
metallic (adj.)
early 15c., "of metal, made from metal," from Latin metallicus "of or belonging to metal," from Greek metallikos, from metallon "metal, ore" (see metal). Specific use in chemistry, indicating the condition of a metal in which it exists by itself, not mineralized or combined with substances which convert it into an ore, is by 1797.
