If empty, glass bottles can be stacked in a player's inventory. When filled with water, the water bottle can be used in the brewing process. After successfully using a brewing stand, a bottle will contain the potion that was brewed. If a player drinks a potion, it will revert back to an empty bottle. However, if the bottle is thrown (as a splash potion), the bottle is lost in the process.
As mentioned above, glass bottles can contain potions. To start making a potion, one must fill a bottle with water. This can be done with a water-filled cauldron, or at any source of Water by right-clicking while the glass bottle is equipped. Afterwards, a player must place up to three water bottles in a brewing stand with one ingredient, such as Nether Wart. If Gunpowder is added to the potion, it will convert to a Splash Potion, so players can throw these at other players or mobs.

- Witches sometimes drop empty glass bottles when killed. They may also drop bottles filled with water when killed. This makes glass bottles a renewable resource.
