Art Jewelry Magazine associate editor Addie Kidd shows you how to anneal metal with a torch. Visit www.artjewelrymag.com/howto for more information and videos.
You suggest letting the silver cool before quenching & pickling. Many professionals suggest it is vital to quench the silver "immediately" hence locking the random small crystal structure of the hot metal.
You're right, the silver doesn't need to cool completely before it's quenched, but it does need to cool to a black heat (no red glow remaining), about 10 seconds. If you quench it while it's still red hot, thermal shock may crack the piece.
The effects of annealing stay until the metal is manipulated in any way - hammering, rolling, bending, etc. Temperature changes can also affect the annealing.

You're quite welcome. Glad you found it helpful.
Super 5 plus plus? :) Nice! And thanks for the enthusiastic feedback!
Very helpful video. Thank you.

Great video! How long should brass be annealed?
Hi! I had a questions about the charcoal block, what do you mean by a reducing atomsphere? Thank you!
What is the temp. during annealing process. Any thumb rule w.r.t. Thickness?
hi. maam, i will ask you a question. what is the purpose of metal annealing??
