Annealing In Bone






Category: ANNEALING

Steel and cast iron may both be annealed in granulated bone. Pack the
work the same as for case-hardening except that it is not necessary
to keep the pieces away from each other. Pack with bone that has
been used until it is nearly white. Heat as hot as necessary for
the steel and let the furnace cool down. If the boxes are removed
from furnace while still warm, cover boxes and all in warm ashes
or sand, air slaked lime or old, burned bone to retain heat as
long as possible. Do not remove work from boxes until cold.
