Copper Bulb Early

by Rczlin

Copper Bulb Early brings the copper bulb block to Minecraft 1.20.1 on Fabric, a version before the block was added to vanilla.

FabricClient and serverMIT LicenseOpen source1.20.1

What it does

The mod backports the copper bulb to 1.20.1 in the form it takes in later versions, with the composition table recipe carried over. Installed on a server and its players, it changes nothing about how existing copper blocks behave. The bulb does not oxidize on its own, and it can be crafted from oxidized blocks.

Copper Bulb Early is published for Fabric only and targets 1.20.1. Both the server and every player need the mod, since the environment is client and server. The code is open source under the MIT License.

Key features

  1. Copper bulb block

    Adds the copper bulb as a placeable block that lights and unlights with redstone.

  2. Matching recipe

    The bulb uses the composition table recipe from the newer version, so crafting matches the later release.

  3. No automatic oxidation

    The bulb keeps its copper state over time and does not oxidize automatically, though it can be made from oxidized blocks.
