The Weathered Copper Lantern is the third oxidation stage of the Copper Lantern, displaying a greenish hue with brown and turquoise patches as the metal continues to corrode. Despite its aged appearance, it functions identically to other copper lantern variants, emitting a light level of 15 and producing a soft green flame. The Weathered Copper Lantern can be placed on top of solid blocks or suspended beneath them, connecting seamlessly to Copper Chains for decorative lighting.

The Weathered Copper Lantern is obtained by allowing an Exposed Copper Lantern to oxidize further over time or by using one directly in creative mode. Applying Honeycomb creates a Waxed Weathered Copper Lantern, preventing additional oxidation, while using an axe can revert it to an earlier stage. The block is waterloggable, non-flammable, and drops itself when broken or when its supporting block is removed. With a hardness and blast resistance of 3.5, the Weathered Copper Lantern combines durability with a rustic, weathered copper aesthetic perfect for atmospheric lighting builds.
