Potions Guide
Water Bottles are made out of 3 glass, placed like a checkerboard shape on the bottom two rows of the table in V formation. With your bottles, right click a water source to fill them
Now, to make most potions, put your bottles into a brewing stand and place nether wart on the top. Other bases work, but netherwart opens up all potions.
Once you have your awkward potion, place whatever potion material you want on the top of the stand and let it brew (besides glowstone or redstone dust)
Once your potion is done, you have four choices: Add redstone dust (increases duration, decreases power), Add glowstone dust (increase power, decrease duration), Add gunpowder (creates splash, but weakens it), or leave it be.
If you choose to add redstone or glowstone dust, you cannot add more to it. It's only a 1 time thing. You may, however, still add gunpowder to make it a splash.
