Except, as Abrasha pointed out, that high karat and pure gold are best drawn
down without annealing. Unlike lower karats, which get too hard and brittle
with too much work hardening and then break, work hardened fine gold remains
ductile, and breaks less when it's not butter soft... Same for almost fine
(like 22K). Fine silver and platinum also don't require annealing much, if at
all.
