Copper Patina

When scraped, oxidized copper blocks would drop some Copper Patina items, which could then be used for two things: - Adding a level of patina to copper blocks - wouldn't require you to wait for eons to get the right oxidization stage, you could just scrape some patina off other copper blocks and apply it there! - A weaker alternative to redstone wire - Let's face it. Everyone who has used redstone for anything more than a pressure plate in front of a door has likely faced the problem of separating lines of redstone. Thus, I propose a Copper Patina wire - it wouldn't connect with redstone wire, but it would connect with other components. It would, however, lose a signal strenght of 2 per wire block, instead of redstone's loss of just 1 strength per block. Copper Patina has the Copper texture but looks like redstone
