If you #dip one potion into another potion, and the potion you are dipping into is not a potion of water, and neither of the potions involved is a potion of polymorph, then you are performing alchemy. If it goes well, the two potions will mix into one new uncursed, diluted potion. For those who are not spoiled, alchemy is difficult to learn.
Though most of the effects of alchemy are dangerous or unpredictable, a few specific recipes are worth it: you can use potions of gain energy to upgrade your potions of healing and extra healing. You can also use potions of gain level for these upgrades, if you don't need to gain levels.
