What is Oxidized Copper Bulb in Minecraft?
An oxidized copper bulb is a unique light source that represents the final stage of aging for a copper bulb. It has a beautiful, fully green color from oxidation. The main purpose of this block is to be a decorative light source that changes its brightness based on redstone. A very special feature of the copper bulb is that its light is a toggle. When it receives a redstone pulse, it will turn on if it was off, or turn off if it was on, and it will stay in that state. The oxidized copper bulb gives off a very dim light when lit, making it perfect for creating moody, atmospheric lighting in ancient ruins or steampunk builds.
How to get Oxidized Copper Bulb in Minecraft
There are two main ways to get an oxidized copper bulb. The first way is to let a regular copper bulb fully oxidize. To do this, craft a copper bulb and place it in the world where it is exposed to the air. Over a long period of time, it will naturally change color through several stages until it becomes fully green. The second way is to craft it directly. To do this, you will need three oxidized copper blocks, one blaze rod, and one redstone dust. You can get oxidized copper blocks by letting regular copper blocks age. Once you have your materials, place the oxidized copper blocks in a column, with the blaze rod in the middle and the redstone dust on top.
How to use Oxidized Copper Bulb in Minecraft
The main use for an oxidized copper bulb is as a redstone powered light source. When you give it a redstone pulse, it toggles its state. The oxidized version gives off a very dim light (light level 4), making it great for subtle, atmospheric lighting. A very important feature of all copper blocks is that you can stop them from aging. If you like the green look of the oxidized copper bulb, you can use a honeycomb on it to wax it. A waxed bulb will never change its color. You can also use an axe on the bulb to scrape off the oxidation, which will revert it to the previous stage (weathered) and also make it brighter when lit. This gives you complete control over the look and brightness of your copper lighting.
