The snapshot marathon for the next major Minecraft update is already in full swing. The Minecraft 23W43A snapshot has introduced the long-awaited update for copper blocks. And with that we got the cool copper lamp. This is an extremely unique light source block with a number of features never seen before. So buckle up, because in this guide we will explore everything related to the Brass Lamp in Minecraft 1.21.
Copper lamp is a light source block that also has redstone properties. It can be turned on and off with redstone power. We have described in detail how to make a copper lamp, how it works and how to use it.

What is a copper lamp?
Copper lamp is one light source block that behaves like other copper blocks. It goes through all four stages of oxidation and can be waxed honeycomb, and can be scraped with an axe. The level of light this block will emit depends on the oxidation phase it is currently in.
Items You’ll Need to Make a Copper Lamp
The recipe for making copper lamps requires quite a few raw materials. Some grinding and preparation is required to get your hands on this cool lamp. Fortunately, according to the recipe you always get at least four balls at a time, so that’s not too bad. To make copper lamps you need the following raw materials:
- 3 copper blocks
- 1 Blowing rod
- 1 Redstone dust
- 1 Craft table or Crafter
Copper blocks can be crafted using nine copper blocks. Blaze sticks are drops from the fire mobs in minecraft. They are ranged and melee mobs that can only be found in the Nether fortress. Since they shoot fireballs at you, it is highly recommended that you take some with you fire-resistant drinks in this scary dimension.
Redstone dust is a precious material that falls during the mining of redstone ores. And finally, the crafting table is a utility block that allows you to perform complex crafting actions. You can easily make it with 4 wooden planks. Alternatively, you can use the new one autocrafter in Minecraft 1.21. It is similar to the crafting table, but only supports crafting triggered by a redstone signal.

- Finally, place the copper blocks surrounding the fire rod into the three empty slots in the main direction as shown below.
- If you use the crafting table, you can click on the brass lamp on the right and move the item to your inventory.

- But if you use the new crafter block, make sure you turn it on once to spit out the items. You can do this with a lever, button, or other redstone power source.
Where to find a copper lamp in Minecraft?
Yes, these beautiful lamps are quite expensive to make. So the alternative way to obtain them could yield more. The copper lamps can be found in the new one tasting room structure in Minecraft 1.21. So far, at the time of writing this, we don’t know much about them. We’re sure they’ll be massive underground structures focused on exciting combat challenges. We don’t yet know what this mysterious building will yield.
How the copper lamp works in Minecraft
The way you use a copper lamp is different from your regular lamp redstone lamp. The first main feature is that this The block turns on and off whenever it receives power. This means that if you power the lamp with a lever after you put it down for the first time, it will turn on. However, if you turn the lever off, the lamp will remain on. But if you activate the lever again, the lamp will turn off.
As you can probably tell from the GIF below, these aren’t the only states of the brass lamp. If the lamp is receiving constant power, a red dot will appear in the center of the texture. This will be the case regardless of whether the lamp is on or off. The switching of all these states can be easily detected by an observer.

Copper Bulb’s surprises don’t stop there. The next fascinating fact is that it emits a level of light depending on its oxidation state it is currently over. Here are the light levels based on oxidation state:
- No oxidation (completely orange) – light level 15
- Exposed version (usually orange with green spots) – light level 12
- Weathered copper lamp (usually green with orange dots) – light level 8
- Oxidized copper lamp (completely green) – light level 4.
You can wax these bulbs to any desired state using a honeycomb, and they will retain that state until you scrape them off with an axe.

Copper lamps themselves are also a redstone power source. If you place a redstone comparator so that it reads the signal from the copper lamp, it will light up when the lamp is on. The signal will always be 15 regardless of the oxidation of the lamp.
However, when the lamp is off, it no longer sends the signal. This is the case for both constant driven states showing the “red dot” in the center.

How to use a brass lamp in Minecraft 1.21
With all the features mentioned above, we have mentioned steps that you need to follow to use a copper lamp in the game.
After you create a brass lamp, place it in the world. Then it’s time to power it. You can use this with any redstone power source, such as a lever, button, or even a block of redstone. Place the button or lever on top of the lamp and activate it by right-clicking. In the case of a redstone block, you can simply attach it to the lamp. When you activate the copper lamp, it turns on and emits light.

But when the power source is turned off, you will see that the copper light still remains on, which was explained in the previous section. This mechanism is important in its own right as a redstone feature and is likely to be present in various farms and other designs of redstone structures.
You can then disconnect the power source and power the copper lamp wherever you want. Moreover, that is possible keep it in the wash if you want it to emit a constant level of light. Otherwise, it will slowly begin to oxidize, releasing weaker light at each stage. The other option is to connect it to a comparator or even an observer, which will detect any change in the lamp’s status (see the GIF above).
If you want to turn off the copper lamp, you will need to supply it with a redstone signal again, using a power source of your choice.

The possibilities that the copper lamp creates are endless. The customizability of the lighting has been dramatically expanded, making this block great in all kinds of different scenarios.
