Bottle

A bottle is an item crafted from glass. When it's placed on tables or a workbench, it turns them into an Alchemy Station allowing the player to craft potions. Standing in or near a body of water will allow you to craft Bottled Water.

One glass block gives two bottles.

You can have 99 bottles in one stack, but holding the right mouse button will only generate 98.

Vendors will purchase a bottle for 4 coppers.

You get approximently 1 bottle for every sand block you have due to glass being made with 2 sand, but 1 glass creates 2 bottles. Meaning 200Sand/2=100Glassx2 =200Bottles.

Combining it with 2 dead goldfish you can craft it to a Social Item named Fishbowl.
