Glass Bottle

The Glass Bottle is a new item planned to be added in the 1.9 update. Glass Bottles are used to brew Potions and Splash Potions with various effects. The Glass Bottle was first added in the 1.9 Pre-Release 2. It is possible to pick up water for potions in the 1.9 Pre-Release 3. You can put them in the Brewing Stand; however, potions cannot be created unless they are filled with water. You can put in various things to make different potions.

The bottles also could be filled with a Cauldron; you right-click on a cauldron with a glass bottle in your hand. the bottle will be filled and 1/4 of the water in the cauldron is taken out. To fill the cauldron, you have to right-click with a bucket of water on it. The water in the cauldron moves, but you won't see and hear splashes when you step in it.
