Copper can be used as a replacement for redstone.
- 1.0- Sol made it so it could be placed like redstone or string (tripwire).
- 1.1- It now requires a Copper Wire.
Copper ore is very common and is found near coal, near the surface.
Makes 3 copper wire.
Weaker than stone, but conducts a charge. Place in item frame to power copper.
- It's a cheaper replacement for redstone, but requires electricity and a lightning rod (or as of 1.1, Copper Swords).
