 In ''NetHack'', '''alchemy''' is the process of [[dip]]ping one [[potion]] into another potion to mix the two into a new uncursed, diluted potion. For those who are not spoiled, alchemy is difficult to learn - there is no in-game indication of which potions are meant to be compatible with each other. While mixing potions at random is [[#Alchemic blasts|generally dangerous and unwise]], there are a set of recipes that can be used to produce fairly consistent results.

 As such, some players tend to wait until they have a stack of at least eight potions to dip before performing alchemy, to get the greatest return out of the dipped-into potion; this includes identifying their [[beatitude]] and accounting for any diluted potions. Make sure to examine your potions between each dip, to avoid accidentally turning a diluted potion into water; splitting stacks to avoid accidents is unnecessary due to how dipped stacks of potions are treated (as described above).

 ===Gem alchemy===
-In SLASH'EM and [[dNetHack]], dipping a valuable [[gem]] into a [[potion of acid]] will generate another type of potion. The potion you get is defined by its randomized description, not by its identified description. For example, if you dip a ruby into acid, you will always get a ruby potion whether ruby potions are full healing or hallucination in your game.

For example, if you dip a ruby into acid, you will always get a ruby potion whether ruby potions are full healing or hallucination in your game.
 There's a chance that dipping will cause an explosion, using up the potion and gem and dealing some damage. If the potion of acid is cursed, it always explodes, like with normal alchemy. You will need one potion of acid per potion produced; stacks of gems will be melted one gem at a time.
