The '''chemistry set''' is a [[tool]] in [[NetHack: The Next Generation]], [[Slash'EM Extended]], and [[SLASHTHEM]], which provides a new way to get specific [[potion]]s, in addition to [[alchemy|existing alchemical schemes]], that is analogous to making [[scroll]]s with the vanilla [[magic marker]]:

* Each chemistry set has a number of [[charge]]s, which in-game represent its stock of potion ingredients, and are consumed when the set is used to make a potion. Each potion type in the game has a specific ingredient cost (see below).
* Like writing scrolls, making a potion requires a "blank" item—an [[#Bottle|empty bottle]].
* You can make potions you have not [[Discoveries|discovered]] yet, with a small chance of success.

''Unlike'' writing scrolls, making potions requires [[#Spellbook of chemistry|knowledge of chemistry]].

Note that a chemistry set is made up of fragile [[glass]]ware, which can shatter easily if thrown or kicked.

==Spellbook of chemistry==
{{spellbook|name=chemistry|prob=50|level=1|type=divination|turns=10|mgc=1|direction=non-directional}}
Before you can use a chemistry set with certainty, you need to be familiar with chemistry. This can be learned by successfully reading a '''spellbook of chemistry'''. As long as you have the chemistry "spell" in your repertoire, you can use chemistry sets. Note that this is not a functional spell, and attempting to cast it will only produce a [[YAFM|funny message]] ("You call upon your chemical knowledge. Nothing happens.").

If you try to use a chemistry set without knowing the "chemistry" spell, you may get the message "Huh? You don't understand anything about such stuff!" and one charge on the chemistry set will be used up.

Trying to use a chemistry set without knowing chemistry will always fail in NHTNG. In Slash'EM Extended you have a 33% chance of being able to make a
potion even if you don't know the spell; otherwise, you will get the same message and lose a charge.

* Slash'EM Extended objects.c line 2108

==Bottle==
{{template:tool|tile=|cost=5|weight=1|color=metal|name=bottle|material=glass}}
Before you can make a new potion, you must have an empty '''bottle''' to contain it. The first thing that happens when you use a chemistry set is that you will be prompted to select a container from your inventory.

Empty bottles can be found as randomly generated tools, but a much more common source of bottles is [[quaff]]ing potions, which will sometimes leave behind the empty container. ("You are left with the empty bottle.") If the potion was taken from a stack, so a new inventory slot is needed for the bottle, but there is no room in your pack, the bottle will drop to the floor. Bottles acquired in this way are naturally uncursed, regardless of the [[BUC]] status of the original potion.

Also, if you quaff a [[milky potion]] but no [[ghost]] appears, presumably due to extinction, you get to keep the empty bottle.

Dipping an empty bottle in a [[fountain]] or [[moat]] fills it with water, making a [[potion of water]].

All other potions cost 2 charges by default.

==Failure==
If the chemistry set doesn't have enough charges to make your desired potion, the bottle will explode ("You seem to have made a mistake!") dealing 10 damage, or 25 if the chemistry set was cursed. Getting killed by such an explosion will give the report that you were killed by an "[[alchemic blast]]".

If you attempt to make a potion you have not yet discovered, you have a [[rnl|luck-weighted chance]] of succeeding; otherwise, the bottle will explode.

-Potions made using chemistry sets are flagged "selfmade" (compare homemade [[tin]]s) and can be defective. When you quaff one, there is a small chance that it will be "bad" (due to an error in the preparation) and possibly have harmful effects, poisoning you for up to 20 hit points ("killed by bad chemical knowledge") or making you [[Vomiting|nauseated]].

 The probability that a selfmade potion will be "bad" and the probability that quaffing it will have a negative effect are each [[Rnl|luck-weighted]], so the higher your [[luck]], the less likely you are to suffer harmful effects from quaffing your own potions.
