This means a copper block enters pre-oxidation after approximately 20 minutes. In Java Edition, when a random tick is given, a copper block has a 64⁄ 1125 chance to enter a state called pre-oxidation. The calculations for the oxidation behavior are as follows: However, if one wishes to increase the oxidation speed, placing oxidized copper blocks around less oxidized copper blocks does not offer a speed improvement over simply placing the blocks 4 apart. This is because a block in a group being less oxidized than the others slows down the oxidation process for all other blocks within 4 blocks of taxicab distance. In Java Edition, groups of non-waxed copper blocks oxidize far more slowly than single copper blocks that are spaced at least 4 blocks apart.

Rain or water does not accelerate oxidation, and covering copper blocks with other blocks does not prevent oxidation. Oxidation of copper blocks relies only on random ticks.

In the last stage (oxidized copper), the block is teal with several green spots. As the oxidation continues (weathered copper), the block is a green color with brown spots. Lightning bolts and axes can remove the oxidation on copper blocks.Īs the block begins to oxidize (exposed copper), it gets discolored and green spots begin to appear. Non-waxed copper blocks have four stages of oxidation (including the initial normal state). Stonecutting blocks of copper gives four times more products than typical for stone. The cut variant can be crafted into slabs or stairs. Weathered or cut variants cannot be crafted back into copper ingots, but the waxed block variant can. Non-waxed copper blocks are completely deoxidized when struck by lightning, and other non-waxed copper blocks nearby are deoxidized randomly.īlocks of copper can be used to store copper ingots in a compact fashion. In addition, using an axe on an exposed, weathered, or oxidized copper block reverts it one stage to a regular, exposed, or weathered copper block respectively.

Using an axe on a waxed copper block turns it into the respective non-waxed copper block. Waxed copper blocks do not oxidize and are identical to the non-waxed version. Copper blocks can be turned into the respective waxed copper blocks by using a honeycomb item on them.
