How to Make Waxed Weathered Copper Bars in Minecraft

Waxed Weathered Copper Bars are the waxed form of the weathered stage of copper bars, showing the green-with-brown-spots texture that copper reaches during oxidation (the slow color change unwaxed copper undergoes over time). Plain copper bars are crafted from six copper ingots set in two rows of three, which yields 16 bars. Copper bars entered Minecraft in Java Edition 1.21.9 and Bedrock Edition 1.21.111, and unwaxed bars pass through four oxidation stages — copper orange, green-spotted exposed, weathered green with brown spots, and oxidized teal — unless waxed with honeycomb. One Weathered Copper Bars block combined with one honeycomb on the crafting grid produces exactly one Waxed Weathered Copper Bars block, and using a honeycomb directly on the placed weathered bars gives the same result.

Waxed Weathered Copper Bars require a pickaxe to break — wooden tier or better — and copper bars mined without a pickaxe drop nothing. Waxed Weathered Copper Bars stack to 64, sit at hardness 5 and blast resistance 6, stay transparent, can be waterlogged, and neither burn nor catch fire from lava. Axes and lightning bolts can remove oxidation on copper bars, while Waxed Weathered Copper Bars keep the weathered stage fixed, so green window grilles, railings, and cage walls never fade to oxidized teal.
