Glass Bottles are small items that can be stacked and are a necessity for brewing. Glass bottles may contain potions and water, with potions only being able to be held after a water bottle has been used in a brewing stand. Any potion can be converted to a Splash Potion with gunpowder.

Glass bottles can be used for potions. To start making a potion, one must fill a bottle with water. This can be done with a cauldron filled with water, or at any source of water by right-clicking on either the cauldron or water source with a glass bottle 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.
