the dark art of bullying rocks into being useful, sharp, or beautiful.
means the science and craft of extracting metals from their ores and shaping their properties through heat, alloying, and working.
from From Greek 'metallon' (metal, mine, quarry) plus '-ourgia' (working, from 'ergon,' deed or labor) — literally 'the working of metal.' It reached English in the 1700s by way of the Latinized 'metallurgia.' The 'ergon' root is a busy one, surfacing also in 'energy' and 'surgery,' so metallurgy is, etymologically, a kind of surgery performed on stone.
