Describe the bug

So, i found myself in search of anvil yet again. For now, you can really craft only 2: bronze one and scavenger. I decided to look deeply into obtaining things for the first one. And i found this recipe sequence: 4 chucks of copper into rod, rod into raw wires (182), then insulate those wires with duct tape (still 182) and make it into ground cables (91). Disassembly of those cables yeilds 1-2 wires back (0.5 wires lost average), while bashing gives same 1-2 wires PLUS 1-5 chunks of copper. Basically it means you can get 2-10 chucks per wire, and you get 182 wires from 4 chunks. So it's like multiplying copper by 100-500, avg about 250-300.

Steps to reproduce

No mods, steps described earlier

Expected behavior

Probably no extra chucks from wire bashing, or single copper items (it still will be dupe, but it's magnitude will be much less severe)
