With brass, the same is not true for copper and its alloys.
So corrosion doesn't prevent further corrosion.
Sorry, but I don't quite follow you there. Rust on iron or steel does
not prevent further corrosion, but exactly the copper alloys brass and
bronze plus pure copper are very well protected by the oxidated layer
on the surface. This even works well i a marine environment thus being
the reason for all the "brasswork" that used to be onboard ships.
Further, the verdigris expands, relative to the metal that was there
before, so mechanisms can be jammed.
Yes ! Also the metal oxides accelerates the tendencies of vegetable
oils to turn into gum-like "snotomers" ( he-he, thank's Julia)
And it looks vile as well.
Depends on the eye of the beholder ;-)
But it is also slightly poisonous.
