This guide will primarily be useful for chemists but may come in handy to any player and especially traitors.

Chemicals

The building blocks of chemistry are aluminium, bromine, carbon, chlorine, copper, ethanol, fluorine, hydrogen, iodine, iron, lithium, mercury, nitrogen, oxygen, phosphorus, potassium, radium, silicon, silver, sodium, stable plasma, sugar, sulphur, sulphuric acid, water and welding fuel. These can be produced from the Chem Dispenser in Chemistry.

You have all sorts of things here, and can make so much. You can make medicines, foam, flash powder, poisons, space lube, window hardener, and so much more. The limit on combinations is a limit that exists only in your creativity (and the game engine). Be sure to be careful though, mixing the wrong chemicals can be bad for your health and please make sure you know what a chemical does before you use it. Experiment at your own risk.

Some pure chemicals are lethal or will cause heavy toxin damage if injected or ingested in their pure form.

Grinding minerals from mining will also get you:

Plasma
Uranium

Emagging a chem dispenser will add:

Space Drugs
Morphine
Toxin
Carpotoxin
Miner's Salve

The NanoMed Plus is your main source of generic toxin when hacked.

Some chemical reactions will require you to heat the reagents in a Chemical Heater. This machine will heat a beaker to the desired temperature, slowing down the heating speed as it approaches the target temperature. If you don't risk making the chemical explode by overheating it (such as Meth) you can just set it to a very high temperature to avoid this.

Machinery

You have all sorts of chems here, and can make many things. You can make medicines, smoke, foam, flash powder, poisons, space lube, acid and much more. The limit on combinations is a limit that exists only in your creativity (and the game engine). Be sure to be careful though, as mixing the wrong chemicals can be bad for your health, and please make sure you know what a chemical does before you use it. Experiment at your own risk.

Chemistry Dispensers

Chem dispensers can be upgraded to unlock more chemicals, allow for more precise macro usage, increased power recharge rate and higher power capacity. If you run out of power, you can disassemble the dispenser with screwdriver+crowbar and rebuild it by first putting the circuit board back, and then all other things but use a full power cell instead of the old one. Then screwdriver to finish. Or you can charge the machine with an inducer .

Better capacitor: faster recharging speed.
Better power cell: larger maximum power capacity.
Better manipulator: unlocks more chemicals. ~~Longer and more complex chemistry macros can be performed. At tier 1 manips, macros round to the nearest 5u, then 3u at tier 2, 2u at tier 3 and 1u at tier 4~~

Chemical Heater

Some chemical reactions will require you to heat the reagents in a Chemical Heater. Unless the recipes says otherwise, these reactions need you to heat the reagents above the required temperature. This machine will heat/cool a beaker to the desired temperature, slowing down the heating/cooling speed as it approaches the target temperature. If you don't risk making the chemical explode by overheating it (like with meth) you can just set it to a very high temperature to avoid this.

Due to a rounding bug you sometimes need to heat chems 1 degree higher than the recipe says.

Upgrading the laser will increase the heating/cooling speed.

ChemMaster 3000

Separates, bottles, and makes pills/patches out of chemicals loaded inside. You can load pretty much any container - beakers, spray bottles, water bottles and so on.
Maximum size for dispensed bottles is 30u, patches 40u and pills 50u. Use a chemistry bag to quickly move large quantities of bottles, patches or pills.
Can be upgraded with bigger beakers to allow a bigger buffer. By default it contains two ordinary 50u beakers for a total buffer volume of 100u.

All-In-One Grinder

Grinds, crushes, liquefies and extracts reagents from materials placed into it.
If there is a significant reagent associated with the item, the Reagent grinder will distill a pure sample inside the collection beaker.
For example: Plasma/gold/uranium/metal sheets, donk pockets, fruits, dead mice.

Smoke Machine

Dispenses any chemical inside as a smoke cloud. Needs to be secured by wrenching first.
A great alternative to smoke grenades, but easily incites lynch mobs.
Can only be obtained through the circuit board being printed, and the required parts being assembled first.

Upgradeable parts:

Click expand to see upgrades:

Manipulator: Unlocks the higher range settings.
Matter bin: Increases maximum capacity.
Capacitor: Increases efficiency.

Metabolism

When a reagent enters a body, it will then "tick" or "cycle" about every 2 seconds (these are called "life ticks", and are not to be confused with server ticks/tickrate). When this happens the body is purged of an amount of every reagent depending on their metabolism rates. This is the rate at which the chemical disappears from your body. It doesn't matter how many chems you have in your body, as they are all metabolized separately. If you are hungry (sluggish), this will happen 20% slower, which makes chemicals have a bigger total effect since they last longer without being weaker per tick. Many mobs are "simplemobs" which means they don't have bloodstreams and can thus not be poisoned, sedated or healed with medicine. Monkeys and most playable humanoids are the exceptions to this.

Active Pure Chemicals

A.K.A. what happens when you eat or splash these. Their metabolism rate is 0.4u per cycle unless said otherwise. Unmentioned dispensable chemicals don't have any effects. Plasma and uranium requires you to grind mineral sheets to acquire.

Chlorine: Causes 1 brute damage per tick to a random body part.
Copper: Can be splashed on metal sheets to create bronze sheets.
Ethanol: A decent alcoholic "beverage", with a booze power of 65. Increases success rate of surgery and flammability when applied externally. Metabolism rate 0.2.
Fluorine: Causes 1 toxin damage per tick.
Iron: Slowly restores blood volume.
Lithium: Causes twitching, drooling, moaning and not being able to walk straight.
Mercury: Causes 1 brain damage per tick, twitching, drooling, moaning and not being able to walk straight.
Plasma: Causes 3 toxin damage per tick. Creates gas form plasma when spilled or heated to 323.15K (50°C). Not to be confused with Stable Plasma, which does nothing.
Radium: Slowly causes irradiation (2 per tick). Creates glowing green goo on floor if more than 3u is spilled.
Sugar: Gives nutrition. Causes hyperglycemic shock if overdosed (200u). Metabolism rate 0.8.
Sulphuric Acid: Causes 1 toxin damage and some instant brute damage to one body part when ingested, and slightly more brute damage when injected. Destroys head-wear and causes burn damage when sprayed or splashed on someone. Counts as a toxin.
Uranium: Causes slight (1 per tick) irradiation. Creates glowing green goo on floor if more than 3u is spilled.
Welding Fuel: Causes 1 toxin damage per tick. Makes people flammable if splashed on.

Narcotics

Narcotics are highly addicitve drugs that can aggressively, or passively, provide a benefit. Be wary as its very easy to become addicted, or overdose, on a narcotic.

As a general rule of thumb, the more of a positive effect (or any effect) a narcotic can provide, the easier it is to get addicted or overdose on it.

People who overdose or get addicted to Narcotics tend to usually end up dying to the negative effects or requiring immedient medical attention. Take in moderation.

Name	Recipe	Description	Metabolism Rate	Overdose Threshold	Addiction Threshold

Pyrotechnics

The manipulation of fire and matter.

Name	Recipe	Description
Stabilizing Agent▮	1 part Iron 1 part Oxygen 1 part Hydrogen	When mixed with certain pyrotechnics, it stabilizes the reaction and prevents the reaction for usage later. The stabilizing agent is not consumed when stabilizing explosives, and one unit is enough to stabilize any amount of explosives. This does not work on everything, so be warned!
Foam Surfactant▮	2 parts Carbon 2 parts Fluorine 1 part Sulphuric Acid	Creates a large amount of foam when mixed with an equal amount of water. This foam carries any reagents along with it in the container, allowing you to apply reagents to large areas at a time. The foam will apply any carried reagents to any walls, floors, objects, or people and animals in the area of the foam. The reagents will be absorbed through a mob's exposed skin and somewhat through clothes unless completely impermeable(hardsuit/biohazard/medical gear). Foam is slippery!
Smoke▮	1 part Phosphorous 1 part Potassium 1 part Sugar	This creates a large cloud of smoke that will take on the properties of everything (if anything) in the container of the reaction. The chemicals in the smoke will touch and react with everything that the smoke touches. Mobs caught within the smoke cloud without wearing a gas mask or breathing through a gas tank will ingest the smoke chemicals. Great for distributing toxins in a crowded area. Can be stabilized with Stabilizing Reagent. If stabilized, heat to 374K to activate.
Flash Powder▮	1 part Aluminium 1 part Potassium 1 part Sulphur	Flashes in a radius that scales up with the amount detonated. Can be stabilized with Stabilizing Reagent. If stabilized, heat to 374K to activate.
Phlogiston▮	1 part Phosphorus 1 part Sulphuric Acid 1 part Stable Plasma	Turns into a spreading plasma fire if not stabilized during mixing. Makes you burn longer, and ignites you. Deals increasing fire damage based on how much you're burning up to 4 fire damage every 3 seconds. Can be stabilized with Stabilizing Reagent. Does not react immediately.
Napalm▮	1 part Oil 1 part Welding Fuel 1 part Ethanol	A substance that burns for much longer then other fuels. Inject it into someone and then apply heat for a warm toasty fireball human.
Sonic Powder▮	1 part Oxygen 1 part Cola 1 part Phosphorus	Deafens in a radius that scales up with the amount detonated. Can be stabilized with Stabilizing Reagent. If stabilized, heat to 374K to activate.
Pyrosium▮	1 part Stable Plasma 1 part Radium 1 part Phosphorus	Comes into existence at 20K. As long as there is sufficient oxygen for it to react with, Pyrosium slowly heats all other reagents in the container up. Useful for delayed reactions.
Cryostylane▮	1 part Water 1 part Stable Plasma 1 part Nitrogen	Comes into existence at 20K. As long as there is sufficient oxygen for it to react with, Cryostylane slowly cools all other reagents in the container down. Useful for delayed reactions.
Chlorine Trifluoride▮	1 part Chlorine 3 parts Fluorine temperature 424k	When created it will create a temporary 3x3 fireball. Comes into existence at 1000K. A flammable substance so dangerous it can burn through the hull of the station. It lights you on fire when it comes into contact with you, and if it gets inside of you will burn you from the inside out. It metabolizes out of your body extremely fast, however.
Sorium▮	1 part Mercury 1 part Oxygen 1 part Nitrogen 1 part Carbon	When detonated it will send any movable object or person flying away from the detonation point. Can be stabilized with Stabilizing Reagent. If stabilized, heat to 474K to activate.
Liquid Dark Matter▮	1 part Stable Plasma 1 part Radium 1 part Carbon	When detonated it will suck in any movable object or person. Can be stabilized with Stabilizing Reagent. If stabilized, heat to 474K to activate.
Meth Explosion▮	1 part Diethylamine 1 part Iodine 1 part Phosphorus 1 part Hydrogen temperature 300k (Room temperature)	If you are making Methamphetamine and mixing the ephedrine last, make sure you're using a chilled container, or it'll blow up just as if it was overheated. Definitely safer to just make the ephedrine separately. Blows up with the same strength as Black Powder.
Black Powder▮	1 part Saltpetre 1 part Charcoal 1 part Sulfur	Sparks, and then creates a violent explosion when heated to 474K.
Nitroglycerin▮	1 part Glycerol 1 part Fluorosulfuric Acid 1 part Sulphuric Acid	A heavy, colourless, oily, explosive liquid obtained by nitrating glycerol. Explodes immediately on mixing (results in 2 units instead of 3). Can be stabilized with Stabilizing Reagent. If stabilized, heat to 474K to activate.
Explosion	1 part Potassium 1 part Water	This explodes immediately on mixing, which may knock you over or even kill you. Only useful in grenade production.
Holy Explosion	1 part Potassium 1 part Holy Water	This explodes immediately on mixing. If it combined at least 75 of each reagent, it results in a more powerful explosion, which also paralyzes and reveals revenants and sets nearby cultists on fire. Otherwise it behaves like a normal Water-Potassium explosion.
EMP	1 part Iron 1 part Uranium	This reacts immediately on mixing, creating an electromagnetic pulse which affects electronics nearby; very useful for causing chaos.
Tesla Shock	1 part Teslium 1 part Water	This reacts immediately on mixing, shooting electric bolts to anyone near the reaction, shocking people and disabling/damaging electronics.
Thermite▮	1 part Aluminium 1 part Iron 1 part Oxygen	A mixture that becomes extremely hot when ignited, and which can burn straight through walls when applied and ignited. Causes minor burn damage to humans when ingested.

Other Recipes

These are either pure reactions that typically leave nothing remaining or other chemicals that have non-medicinal uses. Many of these are useful in the manufacture of grenades, but many can be quite dangerous.

Reagent Delivery

There are different ways you can apply chemicals to a person or the environment.

Delivery types

First of all, there are actually 5 types of delivery, called ingest, inject, vapor, touch and patch. If you are not interested in the details, you can skip to Smoke vs Foam vs others.

Ingest

Ingest and inject both usually do the exact same thing. The reagent simply enters the target's bloodstream. Used by pills, cigarettes, e-cigarettes, inhaling smoke and drinking the reagent directly.

Inject

Works the same as ingest, where the reagent simply enters the target's bloodstream. Used by syringes and IV-drips.

Vapor

Vapor is used by (ranged) spray bottles and foam. A portion of the reagents will enter the bloodstream of the target, but clothes will protect from some/most/all of it depending on clothing. Any hardsuit typically makes the target completely immune to getting it into their bloodstream, if the helmet is closed. But if the reagent has a "vapor" based component, that component will still affect the target, like Fluorosulfuric Acid. See more about foam below, with examples.

Touch

Touch is used by smoke and splashing. If the reagent has a "touch" based component, that component will affect the target (such as the instant heal part of Synthflesh), without being blocked by clothing. Nothing at all will enter the target's bloodstream, with the exception of smoke if the target has no internals on. Currently all "touch" components are also "patch" components. See more on smoke below, with examples.

Patch

Patch is used by patches and medical gels. The reagent enters the target's bloodstream entirely AND if the reagent has a "patch" based component, that component will affect the target. Currently all "patch" components are also "touch" components.

Smoke vs foam vs others

These are the major practical differences between pills, syringes, patches, cigarettes, smoke, foam, splash and spray.

Pills

Pills can be instantly ingested if used on yourself. It doesn't work if mouth is covered. Plasmamen will have trouble taking these. Holds up to 50u.

Syringes

Syringes can inject into people even with their mouths covered, either by hand or with a syringe gun. It doesn't work on players wearing hardsuits or other pierce-immune clothing, unless you use a piercing syringe or manage to aim for an exposed part of their body. Golems are completely immune to syringes (even piercing syringes), but patches do work on them. A syringe holds between 10-60u, depending on type. Common syringes hold 15u.

Patches

Will add all reagents into a person's bloodstream through any clothing, including hardsuits. Also apply touch/patch based effects. Example: A patch of 20u Synthflesh will instantly heal 25 brute and burn (touch component), and also enter the target's bloodstream (which in this case does nothing). Usable by plasmamen. Can hold up to 40u.

Cigarettes

Can be dipped in reagents to be filled. If smoking/vaping, you will slowly ingest whatever reagents the cigarette/cigar/e-cig contains. Though, if the reagents are too diluted, they may not build up in your bloodstream fast enough to have any effect at all. E-cigarettes can be trimmed with a screwdriver and multitool to also create smoke.

Smoke

When a smoke reaction occurs, the smoke will consume any other reagent in its original containers, and spread that reagent to flooring and people/mobs who enter its area of effect. People who enter the smoke will be touched by the reagents. If they do not have internals on, they will also ingest the reagents. The amount of smoke does not dilute the reagents. The reagents will be copied to every individual or tile (not walls, windows or doors) over the cloud's duration. Reagents that are special coded to affect floor/environment (such as blood, acid or Space Cleaner) will do so. Smoke will usually block sight.
Smoke example 1: Smoke containing 20u Synthflesh. Everyone caught in the cloud, including people wearing hardsuits, will slowly heal 25 brute and burn, if they stay in the smoke for its full duration (otherwise they will heal partially). Those who are not wearing internals will also ingest 20u of the medicine, making it enter their bloodstream (which does nothing in this case).

Smoke example: Smoke containing 20u Chlorine Trifluoride(CLF3). CLF3 has a touch(and vapor) component, so everyone caught in the cloud, including people wearing hardsuits and internals, will catch on fire. It will also deal burn damage to the environment, since CLF3 is coded to do so. Those who are not wearing internals will also ingest 20u of the CLF3 and thus, start heating up from the inside, effectively burning from both in and out at the same time.

Foam

When a foam reaction occurs, the foam will consume any other reagent in its original containers, and spread that reagent to flooring and people/mobs who enter its area of effect. The foam will spread slower than smoke and is usually slippery. Reagents will be copied through the vapor type delivery to those affected over the duration of the foam, BUT the reagents will be heavily diluted depending on the amount of foaming reagent used. Any clothing will reduce how much of the reagents will enter a person's bloodstream. Furthermore, foam reagent bloodstream insertion is divided into several 'ticks'. A minimum amount of reagent is required per tick for it to enter a bloodstream. So if too little reagents are contained in the reaction, or too much foam is used, the foam will do nothing. These ticks are counted after dilution and protection from clothing. On the other hand, if you use very small amounts of foam, the reagents may instead multiply in the bloodstream to more than the original amount. Hardsuits with helmets on will make people immune to getting reagents into their bloodstream through foam. Despite dilution, the foam will still copy remaining chems such as acid, CLF3, or Space Cleaner to any tile it touches (but not walls, windows or doors). Foam will not block sight.

Foam example 1: 250u foam containing 10u Cyanide will spread a blue foam that does nothing to those it touches. The poison is too diluted to work at all.

Foam example 2: 20u foam containing 250u Fluorosulfuric Acid. A small area and everyone touched by the foam will have large amounts of acid slowly melting their clothing and the affected floor and items. Those who did not wear a hardsuit with helmet on will also have a large amount of acid in their bloodstreams, depending on what they were wearing and how long they were in the foam. If they had internals on or not doesn't matter.

Splashing

Throwing a beaker, or using a beaker on anything with harm intent, will splash its contents. The longer throw distance, the more the splash will spread out. A grenade will splash its content unless it also contains smoke or foam. Splashing only does touch delivery. This means most chemicals will do absolutely nothing when splashed. Reagents that have special properties to affect environment, such as Water, will do so where splashed (creates slippery tile). Reagents that have a touch component will apply that component only. Example: If you throw a beaker of 80u Synthflesh at someone, you will instantly heal them for 100 brute and burn (and deal up to 150 toxin damage), since Synthflesh is touch/patch based. It doesn't matter if the target uses hardsuit or internals in this case. This means throwing a beaker of poison at someone will do nothing at all. Splashing can apply chemicals such as Thermite to walls.

Spraying

Spraying reagents will apply them to environments (if they have any such effect), and will enter hit people's bloodstreams through the vapor delivery. This means clothing will protect from some/most/all of the reagents, depending on what they are wearing. Using a hardsuit with helmet on makes them immune to getting the reagent into their bloodstream. Reagents such as acid, CLF3, or Space Cleaner will still cause their special effects when sprayed on people/environments, but will not enter the bloodstream if the target is wearing too heavy clothing.

Beyond the Dispenser

Just because it isn't found in the dispenser or the guide above doesn't mean you can't use it! Holy water, slime cores and plenty of other things can provide limitless fun for an enterprising and curious chemist.
