you cant unless you coat it with something.

?? what is the green stuff then?

is there a liquid that will do the job of protecting the copper?

Copper will form an oxide coating (it's a green color) on the surface that acts as a pretty good natural barrier to prevent corrosion deeper in the metal. If you want to keep it looking shiny and new, then you'll need to coat it with something.

Verdigrease. It's p'ison. That's what it is. You just swaller some of it once --you'll see.

what can i use to coat it (cannot absorb microwaves) then?

Steel also doesnt 'rust'. Its oxidizing as well. All metals left unprotected will oxidize. A protective clearcoat often used on Cu++. Lacquer, clear enamel, clear epoxy most common. But wil need eventual recoating...

yeah, but iron oxide == rust. cupric oxide (or whatever?) != rust.

Rust is just a name given to red iron oxidation. Arguing semantics here....

 

[insename2]

what type of coating doesn't absort microwaves?

 

[Krazefinn]

If its an antennae, I dont think any of those commonly available finishes would affect the radio properties either way.
Inside a microwave, I dont know...

try getting some calcium or iron? sacrificial anode FTW 😀
