Cauldron

Cauldrons are used to craft magical potions and charge spells in The Sims: Makin' Magic, The Sims 2: Apartment Life and The Sims 4: Realm of Magic. Sims typically follow recipes written out in a spell book. The Sims 3: Supernatural combines a cauldron and a spell book into a single object known as an alchemy station.

The Sims: Makin' Magic
In Makin' Magic, cauldrons are used to charge spells rather than create potions. They can be purchased from buy mode, or received for free from the Mystery Man when a household first moves into a neighborhood. There are two options, one for adults and one for children. The cauldron for children resembles a toy.

The Sims 2: Apartment Life
Sims automatically receive a cauldron and a spell book in their inventory when they become witches. As a result, cauldrons and spell books cannot be bought in buy mode, and they have no catalog descriptions. However, a cauldron can be sold for §870. Each cauldron is named after the Sim that owns it. For example, if Cassandra Goth owns a cauldron, it will be named "Cassandra Goth's Dangerous Cauldron".

Witches can use cauldrons to craft reagents for spells. A cauldron can also be abandoned, leaving it open to be claimed by another witch.

The Sims 3
In The Sims Store, Sims can purchase the Lord Vladimir's Magic Cauldron which can be used to mix a variety of potions. Teens through Elders can perform the following interactions: brew and drink potions, enchant cauldron, dispose of potion, and conjure.

In The Sims 3: Supernatural, the only cauldron is the one on the Alchemy station.

Lord Vladimir's Magic Cauldron
"Conjure, brew and imbibe your way to magical and mystical excitement with every turn of the ladle ‘round Lord Vladimir’s Magic Cauldron! Collect or conjure dozens of potion components, brew up a magical concoction, and then throw caution to the wind and take a big swig of MAGIC! Mmm…it’s delicious!"

The Sims 4: Realm of Magic
Cauldrons are a craft object in The Sims 4: Realm of Magic. Spellcasters can use them to brew various potions, each with their own effect. Potions are brewed in batches of four, and the Copypasto spell can be used to copy potions when they run out, to avoid having to make more manually. There is a branch of magic specifically devoted to making potions, called Alchemy.

There are two cauldrons available for purchase. One has a normal fire underneath and the other has a magical fire. They both work on lots with the "Off-the-Grid" lot trait. Cauldrons can also be used to cook food.
