Jar

Debuting in A Link to the Past, ceramic pots or jars are found in most games in the Zelda series. When broken, they reveal items such as Rupees, hearts, fairies, bees, arrows, bombs, water, and even Ooccoo. The can be found in houses and dungeons, and sometimes they look like vases. Pots can be broken by throwing them, rolling into a wall with a shelf that houses them, or striking them with a sufficiently powerful sword. They are not to be confused with Magic Jars. Link's fascination with breaking jars is made fun on in Twilight Princess when he examines them eagerly in Hena's Fishing hut, and he can even be expelled from the fishing hut after multiple attempts to break those pots with roll attacks into the wall.

Water Pot
This is just a large pot filled with water. Used in The Wind Waker for temporarily cooling and solidifying lava so Link can travel across safely. These are found mainly within Dragon Roost Cavern.
