Cauldron

A cauldron is a block that can hold water. $$, they can also hold potions, dyed water and lava. It is also a job site block used by leatherworkers in villages.

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

Natural generation


A single empty cauldron is generated in each swamp hut. $$, the cauldrons generated there are $1/3$ full of a random potion.

A cauldron $2/3$ full of water is generated in each igloo basement.

Cauldrons can be found in a few rooms inside of woodland mansions.

Two filled cauldrons can be found inside savanna, taiga, snowy taiga, and snowy tundra village tannery houses.

A single filled cauldron can be found in plains village and desert village tannery houses.

$$, three filled cauldrons can be found in plains village tannery houses.

Crafting
A cauldron can be crafted from iron ingots.

Water
A cauldron can be filled with water by a water bucket on the cauldron. Once completely filled, a cauldron can be used to fill a water bucket by an empty bucket on the cauldron; this empties the cauldron. Despite containing water, using a fish bucket on a cauldron does not fill it with water, but places water against it.

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

A cauldron slowly fills with water when rained upon, if starting empty or with some water. This happens randomly- at 1/20th the rate in which snow accumulates on the ground during snowfall.

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

Water in a cauldron does not absorb explosion damage, make sounds/particles, absorb fall damage, does not damage an enderman, strider or blaze, and fish act as if there is no water inside it. Cauldrons do not deal drowning damage to mobs inside of them.

Pouring water indirectly into a cauldron from a flowing water source block will fill the cauldron completely. Thus is it possible to generate an infinite supply of water from one source block (or full bucket) of water and a cauldron, for example, by placing the cauldron below the water source (or placing the bucket of water in a block above the cauldron instead of on the cauldron itself) and retrieving the water from the filled cauldron with an empty bucket as it constantly refills.

Removing dye
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 on the cauldron with the leather armor, shulker box, or banner in hand. Each wash reduces the water in the cauldron by one level. The water does not become dyed while removing dye from objects.

Applying dye
$$, a cauldron can hold dyed water. a dye on a cauldron filled with water colors the water, consuming the dye. Different dyes may be added to produce mixed colors. leather armor or leather horse armor on the cauldron dyes 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 empties the cauldron.

Potions
$$, a cauldron can hold normal potions, splash potions and lingering potions. a potion on a cauldron empties the potion and increases the level of the potion in the cauldron by one level. A glass bottle can then be on a cauldron with a potion in it, filling the bottle with that potion. The potion can be a normal potion, a splash potion, or a lingering potion, depending on what type was initially put into the cauldron. This reduces the potion in the cauldron by one level.

an arrow on a cauldron that has potion transforms 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 tips up to 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.

Attempting to put water or a different potion into a cauldron with a potion causes an explosion sound, and the cauldron is emptied.

Extinguishing fire
A cauldron with water extinguishes 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 are also extinguished. Entities must reach the water in it. Each entity extinguished causes the water in the cauldron to decrease by one level.

Redstone component


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 outputs 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 the comparator, the comparator does not immediately update.

Storing lava


$$, cauldrons can be used to store lava. When a cauldron is already filled with water, it empties the cauldron and makes an extinguishing sound. A cauldron filled with lava burns any entity inside of it, including mobs that do not take damage from lava, like zombie pigmen, and emits a light level of 15, similar to lava.

Lava inside a cauldron does not interact with water outside of the cauldron. The lava disappears upon putting water in the caudron.

Change profession
If a village has a cauldron that has not been claimed by a villager, any villager that does not already have a profession or job site block may change their profession to leatherworker.

Trivia

 * Arrows "stick" to the water in a cauldron.
 * The inside of a cauldron is 0.25 ($2/3$) blocks tall.
 * A cauldron holding water is the only way to have water in the Nether without the use of commands.
 * 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.
 * The player can still 'use' the cauldron without a bottle or water bucket. However, it has no effect on the cauldron or the player.
