Glass Bottle

Glass Bottles are used to hold the water for potions, which the potion goes into. It can be filled from cauldrons or water sources. It has the texture of a bottle with a cork in.

Uses
Glass Bottles are used to hold the potions for brewing. Filling it up from a water source block is more efficient, since filling from a cauldron put the water down 1/3 of the space, thus making it only have 3 uses from a Glass Bottle. If filled via a water source, nothing happens to the block.
