Tumbling Hardening and Polishing


#1

Hello all,

I read a lot of remarks about tumbling in the archives but I still
have a last question.

This is what I would like to do: After sanding, smoothing my pieces
(14k or 18k gold, maybe platinum) and giving them an intermediate
polishing step I would like to work harden them by tumbling them with
stainless steel shot in a rotating barrel. Do you think it is
necessary to give tumbled pieces a last polishing step to finish
them? Do I loose the hardening effect when I polish my pieces with a
very fine grit?

I will appreciate any comments, I really enjoy reading the posts on
orchid.

  • You can harden your work at any time during the finishing process.
    And you can’t undo the hardening, unless you heat the work. Tumbling
    with steel gives a burnished effect that you may wish to refine with
    a final polishing step. If I wish to have a refined high polish after
    burnishing with steel, I run the work for a day or two in a vibratory
    tumbler with some kind of charged dry media - rouge charged walnut
    shell for example.
