All right, let's make some glass bottles. You need glass bottles to make potions. So you need some glass, and you need to put that glass in a v shape, just like a bucket. Easy to remember. Then once you have a glass bottle, you can go to a cauldron, which you can fill up with a water bucket. Or you can just go to a water source like this one that I've made, or a natural one. And you can fill up those bottles of water. Click that and it pops into your inventory. Right now, potions, you can only have one per slot. This cauldron will hold three bottles of water worth. And that's it, that's how you make a glass bottle.
