A cauldron is a block that can hold water on all versions, along with potions, and dyed water.[Bedrock and Legacy Console editions only]

Obtaining[edit]

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.

Crafting[edit]

A cauldron can be crafted from iron ingots.

Ingredients Crafting recipe
Iron Ingot











A naturally occurring cauldron inside of a witch hut.

Natural generation[edit]

A single empty cauldron is generated in each witch hut. In Bedrock Edition, the cauldron generates filled with a random potion or splash potion.

A cauldron 23 full of water is generated in each igloo basement.

Cauldrons can be found in a few rooms inside a woodland mansion.

Usage[edit]

How cauldrons look with the three different levels of water in them (and empty for comparison).

Water[edit]

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 an intentional feature.[1]

One level of water can be added to a cauldron by using a water bottle on it. One level of water can be removed from a cauldron, filling a water bottle, by using a glass bottle on it.

A cauldron will slowly fill up with water when rained upon, if starting empty or with some water. A cauldron will immediately fill up with water if water flows down into it from a water source located somewhere above the cauldron. (NOTE: Filling by flowing water appears to be deprecated as of testing in version 1.13.)

Water can be stored in a cauldron even in the Nether.

Water in a cauldron will not absorb explosion damage, make sounds/particles, absorb fall damage, will not damage an enderman or a blaze and fish will act strangely inside it.

Removing Dye[edit]

A cauldron with water can wash the dye off of leather armor and shulker boxes, 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.

Applying Dye[edit]

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.

Potions[edit]

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 potions in a cauldron will cause an explosion sound, and the cauldron will be emptied.

Extinguishing fire[edit]

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.

Redstone component[edit]

See also: Redstone circuit

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.

Data values[edit]

Block data[edit]

See also: Data values

In Bedrock Edition, cauldrons use the following data values:

DV Description
0 Empty
1 ⅓ filled
2 ⅔ filled
3 Fully filled

Block state[edit]

See also: Block states
Name Value Description

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

Block entity[edit]

See also: Block entity format

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 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).

History[edit]

Java Edition
1.0.0 Beta 1.9 Prerelease 2 Arrran Cauldron 1.pngArrran Cauldron 2.pngArrran Cauldron 3.pngArrran Cauldron 4.png 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 (download link is broken, mod file can be obtained through the Wayback Machine instead), 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 Prerelease 3 The system was deemed too complex and not user-friendly;[2] hence the cauldron's ability to brew potions was replaced with the brewing stand.[3][4] Cauldrons have been 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.

Trivia[edit]

  • Arrows "stick" to the water in a cauldron.
  • Sneaking over a cauldron will not prevent a player from falling in.[Java Edition only]
  • The inside of a cauldron is 0.3125 (516) blocks tall.
  • A cauldron holding water is the only way to have water in the Nether.
  • The water within does not work like water in the physical terms; the player cannot float/swim in it, and no bubble/water particles are produced.
  • In Legacy and Bedrock editions, the player can still 'use' the cauldron without a bottle or water bucket. However, it will have no effect on the cauldron nor the player.
