Copper , Velveteen , Polishing Machine

Hi,

I have a few questions.

Copper:
First, copper should be like? Should there be any action? Copper can be used instead of rice? Copper is copper must be 100%?
Velveteen:
Velveteen, 100% cotton should be?
Unpainted and must be plain?
Polishing Machine
Is it necessary to use a polishing machine?
What are the advantages of using?

Thank you.

As I assume that this is for electroplating silver, I could answer this with my very recent experience in doing this process.

Either copper / brass (copper+zinc) could be electroplated silver, just as long as silver could be deposited on it. 100 percent copper isn’t a must, as it is just a base for the silver to be deposited on.

I am not sure about ‘rice’, which I assume its brass?

For the velveteen, I used the ones I got the German velvet, as there are varieties of fabrics used by the members from the previous posts, you could use whichever that suits you best.

Plain white/cream ones are fine, as they are usually slightly cheaper, not much cheaper, than the coloured ones. Plus it will go darker as you polish the plates with the powdered rouge.

The orbital sanders is there to save time and muscle spams. I initially did hand-polish before, which quite nicely tone my arms after a half dozen plates, with unfortunate suffering of cramps days later!

I forgot to ask:
Do I need a separate process for copper?
Galvanized, etc..
