A Cauldron is a block that can hold water.
Cauldrons can be obtained by crafting, and can be found in witch huts.
A cauldron can be crafted from iron ingots.
 Natural generation
A single empty cauldron is generated in each witch hut.
To fill a cauldron with water, right-click on the cauldron with a water bucket. A cauldron also has a chance to fill up with water when rained upon.
With water in it, a cauldron can be used to fill glass bottles (turning them into water bottles) or to wash dye off of leather armor. To use the cauldron, right-click on the cauldron with the glass bottle or leather armor. 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.
Zombies and skeletons in a filled cauldron won't start burning from being exposed to sunlight, but each time they don't start burning lowers the water level in the cauldron and it will quickly empty and stop providing any protection. Endermen in a filled cauldron don't take damage from the water in it.
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.
When a cauldron is destroyed (dropping itself as an item), any water inside it will be lost.
A cauldron can be used to wash off the top pattern layer from a banner.
|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:
|Beta 1.9-pre3||The system was deemed too complex and not user-friendly; hence the Cauldron's ability to brew potions was replaced with the brewing stand. 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.|
