Copper in Minecraft has several uses, including construction, crafting lightning rods, and making spyglasses. Here are some of the ways copper can be used in Minecraft:

• Construction and Decoration: Copper blocks can be used for construction and decoration. You can craft cut copper slabs and stairs by filling the bottom row of your crafting table with blocks of cut copper, or by using a stonecutting table. Copper is an excellent block for industrial-style Minecraft builds like factories due to its clean-cut or oxidized looks.

• Lightning Rod: Copper can be used to craft lightning rods, which redirect all lightning strikes in a certain radius to the top of the rod. This can be useful in preventing lightning from striking your home or other structures.

• Spyglass: Copper can be used with an amethyst shard to make a spyglass. This item can be used to zoom in on distant objects and locations.

Copper can be found underground, most commonly underneath beaches, and can be mined with a stone pickaxe or better. Copper blocks will oxidize over time and turn green, but you can wax them to stop the aging process.
