#Copper Grates

To make copper grates in Minecraft 1.21, you'll need four copper blocks and a crafting table. Place the four copper blocks of the same oxidation stage in the diamond shape and you'll make copper grates. If you want to make a specific number of copper grates you can then use a stonecutter, which also provides 1:1 ratio. These blocks are only building blocks and they are available in four oxidation stages. You can scrape them with an axe or combine them with honeycomb.
