Platinum Polishing - No loss of metal

[Jeffreyc87]

There has been a lot of back and forth about polishing gold vs platinum.

Platinum takes more effort to polish, for the simple reason that it does not wear as other precious metals do; consequently, it doesn’t follow the same metallurgical rules.

Platinum has a “liquid” surface. Other metals lose mass over time – prongs wear thin, shanks get thinner, decorations such as Florentine or engravings wear down. All of these deterioration take a lot longer with platinum. The metal even scratches differently.

When you scratch platinum, you are actually just moving the metal aside, whereas other precious metals lose surface area.

This is what I understand. Molecules merely rearrange.

I've read about this.

Pretty amazing

so what you are saying is we should all buy a platona?

[brandrea]

That seems to be the line of thinking yes.

I think when platinum gets all scratched up it looks beautiful and takes on a very cool patina. I don't own a platinum watch, but I do have my wedding band, which shows a lovely patina now

[elcompa]

And that's what makes platinum so damn cool.

Yup!

With the "ice blue, diagonal motif" dial

[airpeace]

so what you are basically saying is if everyone buys Pt, then the no polish army will stop their never polish campaign? Sweet.

Nickel and palladium are the same. The whole family are gummy metals.

Yet when we polish a platinum watch there is still a metallic residue on our polishing wheels, just like with any other watch.

Oh and next time state the source of your post, you copied something from a website.

If you keep reading the article, it goes on to say "It’s also good practice to frequently change emery papers and dress buffing wheels, as well as to recharge polishing buffs after each dressing. When polishing, you are actually removing metal, and some of that metal will adhere to the felts, buffs, and brushes. "

Be careful polishing any metal watches. I am not part of the "never polish army" but regardless of metal, when polishing some metal is removed.

Exactly.

It's high density and it being oddly malleable makes it hard to remove metal and get the desired finishing. But metal is always removed during polishing.
If I need to polish one I'll properly clean my polishing wheels and show before and after pictures, I bet no one will ever question this again after that...

I’ve got a platinum wedding band. I’ve never had it shined up.

Nickel isnt a pgm. https://en.m.wikipedia.org/wiki/Platinum_group

Not worth the hassle, try getting a micron or two of gold or platinum from a lot of dust and polishing paste, not gonna happen.

Every watchmaker I've spoken to seems to agree on this yet this internet myth seems to perpetuate lol......what's true is it's extremely difficult to polish platinum and it takes much more labor to do it. You will lose metal when you polish the hell out of it....just takes much more effort and far longer than say stainless/gold.

Alchemy aside, Pt group is Ni, Pd, and Pt. Their chemistry and properties are the same. Read the table vertically.

I’ve never tried to machine Ru, but have nickel and Pt. They machine the same. Very gummy metal. Doesn’t want to chip off the tools.
