If you're wondering what copper is used for in Minecraft or looking to create your first copper golem, this article covers everything you need to know about the Age of Copper update.
What can you make with copper in Minecraft
The Minecraft copper update 1.21.9 has expanded a lot what you can do with copper in Minecraft. This previously nearly useless material has now multiple purposes beyond simple decoration. It is now one of the most useful resources in the game.
Copper Storage Solutions
One of the most practical additions is the copper chest family. These storage blocks come in all four oxidation states : fresh copper, exposed, weathered, and oxidized plus their waxed variants. Each chest provides the same storage capacity as regular chests but all have a different aesthetic that changes over time.
Copper chests are perfect for themed builds and can be used to create aging storage systems. The exposed copper chest offers a slightly weathered look, while the weathered copper chest shows significant aging. The oxidized copper chest has the characteristic green patina that copper develops over time.
Copper Lighting Systems
The copper bulb is one of the most innovative additions to Minecraft lighting. These bulbs can be toggled on and off using redstone signals, making them perfect for automated lighting systems. The copper bulb emits a warm, amber light that's perfect for creating atmospheric lighting in your builds.
To light a copper bulb in Minecraft, simply provide it with a redstone signal. The bulb will turn on and emit light. When the signal is removed, the bulb turns off. This makes copper bulbs ideal for creating dynamic lighting effects in your builds.
Copper Decorative Blocks
The update introduces an extensive range of decorative copper blocks including:
- Copper shelves: Perfect for displaying items and creating storage areas
- Copper doors and trapdoors: Available in all wood types with copper accents
- Copper stairs and slabs: Essential for building with copper
- Copper fences and walls: Great for creating boundaries and decorative elements
- Copper pressure plates and buttons: Functional redstone components
Copper Automation Components
The copper golem represents the most famous addition to copper automation. This friendly mob can be crafted using copper blocks and will interact with copper buttons. It is really useful to make some automation tasks.
How to make a copper golem in Minecraft
The copper golem is one of the most anticipated additions to Minecraft. Now players can finally craft this helpful companion. Here's everything you need to know about creating and using copper golems.
Copper Golem Crafting Recipe
To make a copper golem in Minecraft, you need:
- 4 Copper Blocks (any oxidation state works, but oxidized is the best)
- 1 Carved Pumpkin or Jack o'Lantern
- 1 Lightning Rod (optional, for enhanced functionality, but not necessary)
Arrange the copper blocks in a T-shape (3 blocks on the top, 1 block on the center below), place the carved pumpkin on top, and optionally add a lightning rod to the golem's head for enhanced redstone capabilities.
Copper Golem Behavior
Once created, the copper golem will:
- Wander around your base and interact with copper buttons
- Press copper buttons randomly, creating redstone signals
- Oxidize over time, changing its appearance and behavior
- Become more sluggish as it oxidizes, but gain unique abilities
The copper golem is perfect for creating random redstone contraptions, decorative elements, and automated systems that don't require precise timing.
How to oxidize copper in Minecraft
Understanding copper oxidation in Minecraft is crucial for getting the most out of the copper update. The oxidation process has been enhanced in version 1.21.9, giving players more control over how their copper items age.
Natural Oxidation Process
Copper items will naturally oxidize over time when exposed to air and water. The process follows four stages:
- Fresh Copper - The original bright orange color
- Exposed Copper - Slightly darker with minor weathering
- Weathered Copper - Significant aging with green patches
- Oxidized Copper - Full green patina
Controlling Copper Oxidation
To oxidize copper in Minecraft faster, you can:
- Place copper blocks near water sources
- Use lightning strikes (copper golems with lightning rods attract lightning)
- Apply honeycomb to wax copper and prevent oxidation
- Use an axe to scrape off oxidation and return to previous stages
Waxed copper variants will never oxidize, allowing you to preserve the original appearance of your copper items indefinitely.
Copper Bulb Mechanics
The copper bulb is one of the most versatile lighting options introduced in the copper update. Understanding how to use these bulbs effectively will enhance your building and automation projects.
How to Light a Copper Bulb
To light a copper bulb in Minecraft:
- Place the copper bulb where you want lighting
- Connect it to a source of redstone (a lever, a button, a pressure plate, etc.)
- The bulb will turn on/off when powered and unpowered
Copper bulbs can be connected to complex redstone circuits. It makes them perfect for creating dynamic lighting systems, security lighting, and automated illumination.
Copper Bulb Applications
Copper bulbs are ideal for:
- Street lighting systems
- Interior lighting with warm/atmospheric glow
- Security lighting that activates with pressure plates
- Decorative lighting that responds to player movement
- Automated lighting for farms and industrial areas
When was copper added to Minecraft
Copper was first added to Minecraft in version 1.17 (Caves & Cliffs Update Part I) in June 2021. However, the copper update 1.21.9 represents the most significant expansion of copper functionality since its introduction.
The original copper implementation was relatively basic, offering only copper ore, ingots, blocks, and a few decorative items. The Age of Copper update transforms copper into one of the most versatile and useful materials in the game.

Use different oxidation states to create buildings that tell a story of aging and weathering. Start with fresh copper for new construction and gradually incorporate more oxidized copper for older sections of your builds.
Copper Storage Rooms
Create themed storage areas using copper chests in various oxidation states. This creates a natural progression from new to old storage, perfect for organizing items by age or importance.
Copper Lighting Systems
