[TheForge] spring temper for brass question

Fri Mar 12 20:56:02 2004

Agreed Bill:

The serious side of this thread has indeed been about hardening a brass
spring not tempering one.

Tempering is a controlled softening of a material and is indeed most common,
metallurgically, applied to steels. There are other materials needing
tempering in the correct sense of the term, glass for one.

Of course if someone asks THIS list about tempering glass they deserve what
they get. <grin>

it ain't real.
