I’ve looked in Silver-Smithing by Finegold & Seitz, Complete
Metalsmith by McCreight and Metal Techniques for Craftsmen by
Untracht… as well as searching some of the Orchid archives, for
info on annealing Fine Silver.
I’m sure its been covered here, but I can’t seem to find much detail
on the subject.
How can I tell when I’ve reached the proper annealing temperature
for Fine Silver? Are there ways to visually tell (like how Sterling
gets to a darkened cherry red when its near 1200 degrees F)?
According to Untracht on p. 246, that’s 572 degrees F (300 degrees C)
for Fine Silver… to be followed by rapid quenching. [He lists the
annealing temperature for Sterling at 1200 degrees F.]
I need to be able to properly anneal the 20 gauge fine sheet silver
OFTEN, without cracking it, while I slowly hammer it into shape. Any
help with some detail, on how to recognize when the optimum annealing
temperature for Fine silver is reached, is greatly appreciated!
