Copper Grate is a decorative and functional variant of copper blocks, featuring a perforated texture that allows partial transparency. While primarily aesthetic, these blocks offer creative potential in ventilation shafts, grills, dungeon designs, or futuristic builds due to their unique see-through pattern.

Copper grates come in four oxidation stages—normal, exposed, weathered, and oxidized—each gradually shifting from orange to greenish teal over time. They can be crafted from blocks of copper using a crafting table or stonecutter, and waxed with honeycomb to prevent further oxidation. Waxed and unwaxed versions exist for each stage.

They are non-solid and do not conduct redstone, allow light and smoke to pass through, and can be waterlogged. Mobs cannot spawn on them. Notably, when two adjacent grates share the same oxidation and wax status, their borders become invisible when viewed through, creating seamless metallic surfaces with depth—perfect for immersive structure design.
