Annealing In Bone





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.
