Oxidised effect


#1

Hi , I have just shaped a silver bangle and it at the annealing
stage. i.e. I haven’t soldered let alone polished it.

Thing is I was fiddling with some emery paper and really like the
effect that rubbing round the outside of the silver had. I love the
contrast between the scratched dark ( I presume oxidised) surface
and the more polished clean silver edge, especially when I rubbed
round the edge with a burnisher.

I was wondering if I would be able to keep this effect after I have
soldered the join, or if I could at least return it to this state if
it should change after the soldering process?

I am very new to silverwork , and im sure there are more correct
terms for what I have just described. But is there a difference
between the dark surface effect you get by an specific oxidising
process and that which I have found just from not placing the piece
in pickle after annealing?

If I can continue with this experiment, and after soldering the join
I can get it to how I want, will it stay like this? And how would I
advise a client on keeping this effect… i.e. if they were to do the
washing up in it would it loose this dark beaten up look and become
silver?

Hi Nikky, I am experimenting a lot with patinas and oxidations. I
have learned that there is an order to do things. Finish all
soldering before working on patinas/oxidation, because re-heating the
piece (especially with silver, where the heat distributes throughout
the piece) can affect the oxidation, especially if you are going for
particular colors. Then do polishing. Finally, set stones last.

Keep in mind that putting a piece into an ultrasonic cleaner can
remove oxidation like the kind you get from Liver of Sulfer.
