Rhodium plated Brass

[Mitchell Tutty]

I have a client who wants a rhodium plated brass plaque engraved.
I've just bought my first bottle of cermark and have absolutely no experience using it.
Will a 60 watt laser using cermark mark the Rhodium? Does anybody have any experience using it? recommended settings, or things to watch out for? All would be appreciated!

Cermark does not work on Silver, Gold, or Platinum and since Rhodium is a precious metal, a member of the platinum family, it will not work. Stainless Steel is the best medium
