Cauldrons can be mined using any pickaxe. If mined without a pickaxe, it will drop nothing. When a cauldron is destroyed, its contents will be lost.

A cauldron can be crafted from iron ingots.
A cauldron 2⁄3 full of water is generated in each igloo basement.
Cauldrons can be found in a few rooms inside a woodland mansion.
A cauldron can be filled with water by using a water bucket on the cauldron. Once completely filled, a cauldron can be used to fill a water bucket by using an empty bucket on the cauldron; this empties the cauldron. Despite containing water, using a fish bucket on a cauldron will not fill it with water, but will place water against it. This is a completely intentional feature.
A cauldron will slowly fill up with water when rained upon, if starting empty or with some water.
Water can be stored in a cauldron even in the Nether.
A cauldron with water can wash the dye off of leather armor and shulker boxes[upcoming 1.13], and can remove the top-most pattern layer of a banner, by pressing use on the cauldron with the leather armor or banner in hand. Each wash reduces the water in the cauldron by one level.
A cauldron can hold dyed water.[Bedrock and Legacy Console editions only] Tapping the cauldron with a dye in hand will color the water, consuming the dye. Different dyes may be added to produce mixed colors. Tapping leather armor or leather horse armor on the cauldron will dye that item the color of the water, reducing the water in the cauldron by one level for each item dyed.
Attempting to add water or potion to dyed water will empty the cauldron.
A cauldron can hold potions:[Bedrock and Legacy Console editions only] normal potions, splash potions and lingering potions. Tapping the cauldron with a potion in hand will fill the cauldron one level with the potion, and turn the potion in hand to a glass bottle. The cauldron can then be tapped with an empty glass bottle in hand to fill the bottle, turning it to a drinkable potion or a splash potion, reducing the potion in the cauldron by one level.
Tapping on a cauldron that has potion with a normal arrow in hand will turn the arrow into a tipped arrow with that potion effect, and reduce the potion in the cauldron by one level. Tipping multiple arrows at once can be more efficient, and it may use more than one level at once. 1 level of potion will tip up 16 arrows, 2 levels up to 32, and a full cauldron can tip a full stack of arrows, resulting in 21.33 tipped arrows per potion.
Mixing potions or mixing water with potion in a cauldron will cause an explosion sound, and the cauldron will be emptied.
A cauldron with water will extinguish entities on fire that fall into it. This includes mobs, players, items (if they land in the cauldron before burning up) and flaming arrows. Flaming arrows stuck into the side will also be extinguished. Each entity extinguished will cause the water in the cauldron to decrease by one level.

A cauldron can act as a power source for a redstone comparator. With a cauldron behind it (either directly, or separated by an unpowered solid block), a comparator will output a signal strength proportional to how full the cauldron is: 0 for empty, 1 for one-third full, 2 for two-thirds full, and 3 for completely full. However, if there is a block between the cauldron and comparator, the comparator will not immediately update.
A cauldron's fullness is defined by its block data.

In Bedrock Edition, a cauldron has a block entity associated with it that holds additional data about the block. The block entity has the id name
Block entity data
- Tags common to all block entities see Template:Nbt inherit/blockentity/template
CustomColor: This tag only exists if the cauldron stores dyed water (i.e. PotionId is -1 and the block data value is greater than 0); stores a 32-bit ARGB encoded color.
Items: List of items in the container.
: An item, including the slot tag. Unsure of what this is used for.
- Tags common to all items see Template:Nbt inherit/item/template
PotionId: If the cauldron contains a potion, this tag will store the ID of that potion. If there is no potion stored, then this tag is set to -1.
SplashPotion: Whether or not the cauldron stores a splash potion; stores either 0 (false) or 1 (true).
isMovable: Whether or not the cauldron can be pushed by pistons; stores either 0 (false) or 1 (true). The default is 1 (true).
