How to duplicate all ores in minecraft Update Aquadic and Village Pillage Update

You can duplicate any item that can be crafted into a block of 9 and crafted back into 9 items. Works for every edition but xb1 and switch (as far as I know)

First you need to have at least 18 of the item you want to dupe, whether that be iron diamond gold etc., and craft them into two blocks. After that, register the pick block button to a button on your controller, and place a crafting table and one of the blocks side by side.

Place the second block into your inventory, look at the first block and repeatedly press either the right or left bumper while simultaneously pressing the pick block button. Once you see two blocks appear, open the crafting interface (dont use the crafting table) and craft them back into individual items and then back into blocks again. Repeat this process until you are satisfied with the amount you have.
