Do you mark your metal on one side so that you consistently heat
the same side? or do you alternate? or have you found that it makes
Kay I usually heat both sides of the metal during each heating
cycle. Then there is no reason to mark the metal.
I will slowly heat one side until the sterling slightly changes
colour. I try not to get it all the way up to dull red. I will remove
the heat just before it gets there.
I then flip the piece over and gently heat it for a few seconds until
the reverse side also changes colour. Since sterling is such a good
conductor of heat it does not take long for the second side to come
up to the correct temperature.
Also, I generally do not lay the silver flat. I prop it up against
the fire brick so that there is air circulating behind it. Don't know
if it makes any difference, but it is the way I learned to do it and
it always works.
Takes about 5-10 heating, quenching and pickling cycles before the
silver is well coated and develops a very uniform layer of white.
This is the way I prepare silver for keumboo.
