One of the most unexpected, yet appreciated, additions of Minecraft 1.21 is an expansion of the copper blocks available to builders. There are five new copper blocks total, all of which can be found in trial chambers, the largest 1.21 feature, and crafted by players. This makes it quite easy to get these blocks in large numbers, making them great for building large survival bases.

Everything players need to know about these blocks, from how to craft them to what they look like, can be found detailed down below.


How to use all of the new Minecraft 1.21 copper blocks

The first new copper block to discuss is the chiseled copper block. These blocks are made using two cut copper slabs placed on top of each other in the crafting interface. They feature quite a distinct texture, making them great for decoration. This is the only real use of the block.

There are different levels of oxidation, as with all copper blocks, and players can put wax on these to stop them from rusting.


Copper Grates

The second new copper block is the copper grate. These blocks are crafted using four of the same matching copper blocks, arranged in a diamond. This will make four grates, meaning the blocks are converted at a generous one-to-one ratio. They can also be covered with honeycombs to keep them from oxidizing.

The uses of copper grates are only limited by the player's imagination. These blocks are decorative and semi-transparent. They allow light through, making them potential window replacements. Additionally, they can be waterlogged, making them even more useful as Minecraft decorations.


Copper Doors

The next new copper block is the copper door. This block requires six copper ingots to make a set of three doors, the same rate as the other wooden and metal doors in the game.

Unlike iron doors, copper doors do not have to be opened with redstone signals. They can be opened by hand, making them much more convenient to use in amazing Minecraft steampunk builds. That said, they can be opened and closed using redstone, just like all other doors. Coupled with that, they can be covered in honeycomb to prevent oxidation.


Copper Trapdoors

Copper Trapdoors are similar to copper doors, as they generate naturally within trial chambers and serve as another way to keep dangerous, hostile Minecraft mobs at bay. Originally requiring six copper blocks to make two trapdoors, the recipe has thankfully been changed to require only six copper ingots for two trapdoors.

Using these items is simple. All you need to do is place the trapdoor down and interact with it. This will cause it to open and close. Redstone can also cause the trapdoor to open and close. They can also be used in Minecraft's classic mob farm design, just like any other trapdoor, since mobs will see them as a full block. They can be waxed to prevent rusting.


Copper Bulbs

The final new copper block is the redstone bulb. This interesting variant can be crafted with three matching copper blocks, redstone dust, and a blaze rod. They can also be found in varying states of oxidation, lighting up the interiors of Minecraft trial chambers. You can use an axe or lightning to remove excess rust from a copper bulb.

Using these new copper blocks is easy, as they only need to be laid down. These variants might appear to be a redstone light source, but they emit regular light. They do not need power to cast light, instead producing it based on the level of oxidization. When completely unoxidized, it emits a light level of 15, and when fully oxidized, it emits a light level of four. Wax can prevent these blocks from rusting.
