Cauldron in Minecraft: water, lava, dyes and potions

The cauldron is crafted from iron ingots and holds water, lava or powder snow. You need a pickaxe to collect it, and breaking it loses whatever is inside. It takes three levels of water in Java and six in Bedrock: a bucket fills it completely, and each bottle adds or removes one level in Java or two in Bedrock.

It fills itself in a few ways. Rain slowly adds water, and snowfall adds powder snow. More useful is placing it under a pointed dripstone, at most 10 blocks below, with water or lava directly above the dripstone: it drips and gradually fills the cauldron. That makes lava renewable. Cauldron water even works in the Nether and does not freeze in cold biomes.

Undyed water is for washing: it strips colour from leather armor, wolf armor and shulker boxes, and removes the top layer of a banner. Add dye and the water takes its colour, ready to dye leather pieces. In Bedrock it also stores potions, and dipping arrows in it makes tipped arrows; done carefully, one potion gives up to 32.

It puts out any burning entity that falls in, using up one level. With lava it gives light level 15 and burns whatever enters. A comparator reads its level from 0 to 3. It generates in swamp huts, igloo basements, village tanneries and some woodland mansion rooms, and it is the leatherworker's job site block.
