Guide to chemistry

This guide will primarily be useful for chemists but may come in handy to any player and especially traitors. See Chemical recipes for simplified step-by-step instructions on how to make complicated chemicals (sometimes outdated), and for info about using the dispenser's recipe recording function. If you don't have a chem dispenser, see the Guide to Ghetto Chemistry.

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.

Dispenser.png 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.

Chemical_Heater.png 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.gif 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.

Blender.png 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.png 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.

Plumbing
On some maps the chemists have access to a large empty area with plumbing tools. The available chemicals those can synthesize should be the same as with an unupgraded chem dispenser, but the workflow is more like a production line chem factory instead of instant dispensing. See the Guide to plumbing to learn more about this system. You may still have access to the pharmacy though, which has chem dispensers.

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 the speed of surgery procedures 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.

Components
These are very basic chemicals that you'll use in a lot of other more complicated chems. They can still be toxic, though.

Hover a chemical component to see tooltips. On Firefox-based browsers the tooltips might block clickable links. If you find an incorrect recipe then drop a comment in the discord wiki-general.

Medicines
"And that's how I lost my medical license!" Don't be this guy. Make these. Lots of these.

Core Healing Medicines
These healing drugs form the "core" drugs used to heal the most common forms of damage. All other medical drugs outside of this section are either harder to make upgrades, or highly specific forms of healing for rarer situations.

Superior Healing Medicines
These healing drugs are harder to make than the core healing drugs, however they are significantly better at healing.

Also, many upgraded drugs can be overdosed with, leading to a negative outcome. Be sure to monitor how many units of chemicals someone is injected with.

Unique Healing Medicines
These healing drugs preform a unique function that is not commonly used or seen in game.

Non-craftable Medicines
These healing drugs are used in some situations, but are otherwise uncraftable.

Narcotics
Narcotics are highly addictive 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.

Pyrotechnics
The manipulation of fire and matter.

Explosive Strength
For chemicals which are explosive, you may notice an 'explosive strength' listed in the description. This is a multiplier that directly affects how large of an explosion a given quantity of the reagent will produce. A few types of explosion have a 'modifier', which adds a flat amount to the size of the explosion. By default the outer 'light impact' radius of an explosion is equal to √(mod+quantity*strength)*√2, while the heavy impact radius and devastation radius is one half and one quarter of that, respectively. Chemical explosions are not a subject to the standard TTV Bombcap. Eventough it doesn't have a hardcoded maxcap currently the biggest possible explosion is that of 2100u custom made chemical payload bomb.

Note that all non-standard explosions or other AoE pyrotechnics, such as Flash Powder or Liquid Dark Matter, do not work like this. The scaling and max size of these effects vary on a case-by-case basis.

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.

Virology Recipes
These chemicals are used to mutate viruses, and have few uses beyond that.

There are also chemicals that do nothing, which can be found in Strange seeds. Example: Plastic Polymers.

Mutation Toxins
Obtainable through xenobiology, these chemicals transform humaniods in other humanoid races.

Toxins
The deadliest of deadly chemicals. You can get a bunch of these through the traitor uplink, but if you don't wanna waste telecrystals you can mix it.

Lavaland Chemicals
Found primarily in Lavaland flora.

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. Probital works best when ingested.

Inject
Works the same as ingest, where the reagent simply enters the target's bloodstream. Used by syringes and IV-drips. Syriniver works best if injected.

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. Hercuri works best as vapor.

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 or gas mask 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! Drinks, slime cores and plenty of other things can provide limitless fun for an enterprising and curious chemist.
