Description

Raw Copper Block compresses nine raw copper into a single block on the crafting grid — the largest input-to-output ratio of any storage block in the game. The reverse recipe also works: place one block in any crafting slot and receive nine raw copper back, lossless. This makes it purely a storage solution for the enormous quantities of pre-smelted copper that pile up after even a moderate mining run, especially given how common copper veins are in dripstone caves and deepslate layers below Y=0.

The visual presentation is rough chunks of unrefined ore packed tightly together, with the same orange-brown tone as raw copper itself. Unlike the smelted copper block, this one does not oxidise — there is no green-tinted variant — because it represents the unprocessed raw material rather than the worked metal. Builders sometimes use it as a textured accent on industrial bases, miner-themed builds, or as filler for cave-themed builds where the rough texture suggests unprocessed wealth waiting to be smelted.
