The Exposed Copper Chain is the second oxidation stage of the Copper Chain, showing light tarnishing and green spots as it begins to weather. Like other copper variants, it is both decorative and functional, used to hang or connect objects such as lanterns, copper lanterns, bells, and hanging signs. It can be placed vertically or horizontally, connects seamlessly to other chains, and does not require support to remain suspended in midair.

The Exposed Copper Chain can be crafted by allowing a regular Copper Chain to oxidize naturally over time or by using one in its exposed state obtained through creative mode. Players can prevent further oxidation by applying Honeycomb to create a Waxed Exposed Copper Chain or restore it to its previous state using an axe. It maintains the same hardness, blast resistance, and functionality as other chain types, making it ideal for builders seeking a slightly aged copper aesthetic.
