Glass Bottle

The Glass Bottle is an item that was added in 1.9 Pre-release 2. It is possible to pick up Water with bottles to make Water Bottles, which are a vital part of Brewing.

Usage
Glass bottles can be used to make Water Bottles.

Bottles may only be filled by using a water source block or a filled Cauldron. If filled via water source, the water will be unaffected. If filled via cauldron, however, 1/3 of the water in the cauldron will be removed. Therefore, using a Cauldron to fill bottles is inefficient, except in the Nether where it is the only way to fill bottles.

History
The Glass Bottle was first added in Beta 1.9 Pre-Release 2. They were given their sole function of picking up Water for Potions in Beta 1.9 Pre-Release 3.
