Wind charge oxidizes copper

A secondary use for wind charges could be to oxidize copper faster. Either shot from a dispenser or thrown by a player. It makes real world sense as oxygen helps oxidize copper, and in game it fits into the lore of the Trial Chambers containing a massive amount of already fully oxidized copper blocks. The amount of wind charges should be balanced, definitely not 4 to fully oxidize, maybe the same mechanic as it takes to fill a composter?
