A cauldron is a block that can hold water and, in Pocket Edition, potions.

Obtaining[edit | edit source]

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

Natural generation[edit | edit source]

A naturally occurring cauldron inside of a witch hut.

A single empty cauldron is generated in each witch hut and in each igloo with a basement.

Usage[edit | edit source]

How cauldrons look with the three different levels of water in them (and empty for comparison).
An example of a cauldron used in a redstone circuit.

To fill a cauldron with water, press use on the cauldron with a water bucket. This will work even in the Nether. A cauldron also has a chance to fill up with water when rained upon. Once filled, a cauldron can be used to fill an empty bucket.

With water in it, a cauldron can be used to fill glass bottles (turning them into water bottles), though water bottles cannot be used to refill a cauldron. A cauldron with water can also wash dye off of leather armor or remove the top-most pattern layer of a banner. To use the cauldron, press use on the cauldron with the glass bottle, leather armor or banner.

A cauldron will extinguish mobs on fire (including players) who fall into it. Each use (including extinguishing mobs) causes the water level in the cauldron to decrease by one-third. After it has been used three times, it will be empty and must be refilled before additional uses. Endermen in a filled cauldron don't take damage from the water in it.

Redstone component[edit | edit source]

See also: Redstone circuit

A cauldron can act as a power source for a redstone comparator. With a cauldron behind it (possibly 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.

Pocket Edition[edit | edit source]

In Pocket Edition, cauldrons can hold potions. Tapping the cauldron with a potion in hand will fill the cauldron one level with the potion. The cauldron can then be tapped with an empty glass bottle to fill the bottle with the potion. Mixing potions in a cauldron will cause it to make an explosion sound and the potions disappear. Cauldrons in a witch hut will spawn filled with a random potion. These potions can be used to make tipped arrows.

The color of water inside of cauldrons can be changed with dyes. Using this method will allow the player to dye leather armor and leather horse armor.

Cauldrons can be refilled using water bottles.

Data values[edit | edit source]

A cauldron's fullness is defined by its block data. In the future, it is planned for block states to replace block data.

Block entity[edit | edit source]

See also: Block entity format

In Pocket Edition, a cauldron has a block entity associated with it that holds additional data about the block. The block entity has the id name Cauldron.

  • 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.

    •  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).

Block state[edit | edit source]

Name Value Description

0–3 Water level in a Cauldron, "0" being empty and "3" being full.

History[edit | edit source]

How potions were brewed in Beta 1.9 Pre-Release 2, if enabled through a mod.
Official release
1.0.0 Beta 1.9-pre2 Added cauldrons. Originally intended to be used for the creation of potions, cauldrons were not assigned a block ID, hence making potions unobtainable. Cauldrons could be made to work with a mod, where the following was revealed:
  • Cauldrons could be filled with a water bucket.
  • Applying a potion ingredient to the water would cause it to change to a differently-colored lava texture, and adding any further potion ingredients to the filled cauldron would cause the liquid to change color.
  • Scooping out a potion with ingredients applied would cause the potion to have an effect related to the ingredient, e.g. a potion brewed with a magma cream would have Fire Resistance as an effect.
Beta 1.9-pre3 The system was deemed too complex and not user-friendly;[1] hence the cauldron's ability to brew potions was replaced with the brewing stand.[2][3] Cauldrons were given a Block ID and Item ID and made craftable, but all abilities to apply potion ingredients to a cauldron filled with water were removed.
1.3.1 12w22a Cauldrons fill with water if placed outside during rain or a thunderstorm.
1.4.2 12w34a Holding a piece of dyed leather armor and right-clicking a water-filled cauldron will wash away all dyes applied to the leather armor.
12w40a Empty cauldrons can be found in witch huts.
1.6.1 13w18a When used with a redstone comparator, cauldrons now output a signal varying in strength according to the amount of water inside.

13w43a Cauldrons now extinguish burning entities.

1.9 15w43a A cauldron now generates within igloo basements, 23 full.
15w44a A full cauldron can now be emptied with a bucket, filling the bucket with water.
