My dear /sci/enfrens, ITT we will attempt recreating the RTSC LK-99.

The aim here is to make this process as simple and affordable as possible. To create instructions so easy anyone willing to replicate can have a clear guide to follow, regardless of their knowledge and background. Please contribute as this should be a team effort. The more frens join, the higher our odds of success will be.

Here are the points we will be going through in order to achieve this.

1. List of materials and how to obtain them
2. List of equipment and how to obtain it
3. Review together the South Korean methodology, set up three variants (including original) and begin testing.

Materials: let’s please star by reviewing this. Let’s make sure all the equipment, instructions and sources for each material is correct. Let’s also add a link to reliable suppliers so frens who want to save time can just buy the materials they need.

PbO - if there is a better way please update the following.
you will need: lead nitrare (tutorial for lead nitrate: https://youtu.be/ZYNEHwHAtqk [Open]) , a stainless steel crucible, a blow torch
Here is a tutorial: https://youtu.be/KeDV3zmowwM [Open] [Open]

PbSO4 - need to confirm this is a viable method, if not please propose alternative.
You will need: old car batteries
>is the white stuff that collects on the plates of car batteries that have been sitting around too long. go to local mechanic and ask him access to the discarded batteries. Scrape the positive electrode to extract any concentration of PbS4 that has formed.

Cu - you will need: copper sulfate, aluminum foil, h2o, and salt

Step 1 - Preparation for lanarkite, Pb2SO
>PbO and PbSO4 powders were uniformly mixed in a molar ratio of 1:1 in an agate mortar with a pestle. And then, after the sample was transferred to an alumina crucible, it was reacted at 725 °C for 24 hour in a furnace. After completion of the reaction, white sample was obtained. It was pulverized with the mortar.

Step 2 - Preparation for copper phosphide, Cu3P
>Cu and P powders were mixed in each composition ratio. And the sample was transferred in a quartz tube. The tube was sealed and reacted at 550 °C for 48 hour in a furnace. After taken out from the tube, a dark gray ingot was obtained and pulverized.

Step 3 - Sample Synthesis and Preparation of LK-99
>For the sample synthesis of the LK-99, the general solid-state reaction was used. Lanarkite and Cu3P were uniformly mixed in a molar ratio of 1:1 in an agate mortar with a pestle. The sample was put into a reaction tube and reacted at 925°C for 10 hr. After the reaction, a dark gray ingot was obtained reproducibly and then made into the shape of thin cuboids for electrical measurements. For other analyses, it was pulverized and used as the form of powder. The reagents used for the above solid- state reaction was PbO (JUNSEI, GR), PbSO4 (KANTO, GR), Cu (DAEJUNG, EP), and P (JUNSEI, EP).

if so i hope you'll get a good results

[Sunny No.15651262]

>>15651239
Yes, that’s our aim. However before we get started with the actual attempts. we must first complete the list of materials, where to get them, how to process them. We need to make a list of equipment necessary. We need to go over the Korean methodology. We have to set up different variables. And o bunch of other stuff I’m probably overthinking. We have to create a clear full guide on how to recreate LK-99. Then we start testing!

apparently some people are saying ze rock floats because of ferromagnetic iron impurities in the samples (proven by xrays)
idk how it would get in there but maybe try and minimise it in your synthesis

also people say its so hard to find superconductivity because its limited to tiny1 dimensional channels so i guess measure all over the place or try and find the grain boundaries
good luck

Thanks for doing this, Sunny.
I'm the guy from the last thread who was kinda thinking about trying it in two more weeks. How many watts does your kiln use maximum, and how many does it use on average to maintain its temperature once it has reached the maximum? Does it have any exterior parts that could melt or catch fire if I wrapped the whole kiln in insulation?
Trying to figure out if a kiln is even feasible for me.
I live off grid with 1600W of solar panels. Want to put up 400W more regardless of kiln. Batteries hold 5kW-h but I need to keep a least half of that in reserve.

Also calling on anons to come up with a better way of getting red phosphorus. Burgers should be careful about researching this and should definitely not attempt to buy red phosphorus online. I came up with some methods involving phosphoric acid but have doubts about all of them.

Think I'm going to have to sit this one out due to my 120V, 1500W inverter. My generator isn't much better.
If things really start happening I could possibly Max Max my own small kiln. I already made a heating system to stop my prep stash from freezing when I'm gone. It redirects the sun juice directly into the heating system when needed, bypassing the inverter and the batteries.

COMPOUNDS
The reagents used for the solid- state reaction of LK-99 are PbO, PbSO4, Cu, and P.

PbO
>warning:

>Materials you will need:
- Precision scale
- lead nitrate (tutorial for lead nitrate: https://youtu.be/ZYNEHwHAtqk))
- 1 stainless steel crucible

- Tongs or heat-resistant gloves
- Safety glasses and gloves
>procedure
1. Ensure you are working in a well-ventilated area and follow appropriate safety precautions, including wearing protective gloves, safety glasses, and working with the necessary equipment.
2. Obtain a piece of lead metal or a lead-containing source, such as the terminals from a lead-acid battery.
3. Clean the lead or lead-containing source to remove any surface impurities or contaminants. You can use a mild detergent and water to clean it, followed by rinsing with distilled or deionized water.
4. Preheat your furnace to a temperature of around 800-900°C (1472-1652°F).
5. Place the cleaned lead or lead-containing source in a crucible or a heat-resistant container.
6. Transfer the crucible or container with the lead into the preheated furnace using tongs or heat-resistant gloves.
7. Allow the lead to heat in the furnace for a sufficient amount of time to oxidize. The lead will react with the oxygen in the air to form lead oxide (PbO). The duration will depend on the temperature and the size of the lead sample, but typically 1-2 hours should be sufficient.
8. After the desired reaction time, carefully remove the crucible or container from the furnace using tongs or heat-resistant gloves. Exercise caution as the crucible will be hot.
9. Allow the lead oxide to cool down to room temperature.
10. Once cooled, you can collect the lead oxide (PbO) as a reddish-brown or yellow powder. Take care to handle it with gloves and avoid inhaling the powder.

PbSO4
>warning:
- Lead compounds are highly toxic. Safety precautions must be in place to protect yourself.
>tutorial:
- https://youtu.be/bnbxYPMBz9M
>Materials you will need:
- Lead (Pb) metal or lead-containing source (e.g., lead-acid battery terminals)
- Sulfuric acid (H2SO4) solution (concentration around 1-2 M)
- Glass container or beaker
- Stirring rod or glass rod
- Distilled or deionized water
- Filter paper or filter funnel
- Wash bottle with water
>procedure:
1. Ensure you are working in a well-ventilated area and follow appropriate safety precautions, including wearing protective gloves and eyewear.
2. Obtain a piece of lead metal or a lead-containing source, such as the terminals from a lead-acid battery.
3. Clean the lead or lead-containing source to remove any surface impurities or contaminants. You can use a mild detergent and water to clean it, followed by rinsing with distilled or deionized water.
4. In a glass container or beaker, prepare a sulfuric acid solution with a concentration of around 1-2 M. Take care when handling sulfuric acid, as it is corrosive. Always add the acid to water slowly and while stirring to prevent splashing.
5. Immerse the cleaned lead or lead-containing source into the sulfuric acid solution. Ensure that the lead is fully submerged.
6. Allow the reaction to proceed for several hours or overnight. During this time, lead sulfate (PbSO4) will form on the surface of the lead as a white precipitate.
7. After the reaction period, carefully remove the lead or lead-containing source from the solution, taking care not to disturb the formed lead sulfate precipitate.
8. Rinse the lead sulfate precipitate with distilled or deionized water to remove any residual acid or impurities. You can use a wash bottle or carefully pour water over the precipitate while collecting it in a filter paper or filter funnel.
CONT.

[Sunny No.15654483]

>>15654481
9. Once rinsed, allow the lead sulfate precipitate to dry. You can place it on a filter paper or a clean surface and let it air dry.
10. Once dry, you can collect the lead sulfate as a white powder. It is recommended to handle it with care and avoid inhaling the powder.

>description:
the quickest way to make relatively pure copper powder with very common materials while avoiding the annoying electroplating is chemically precipitating it out from solution.
>procedure
-1. you can just eyeball the measurements. just add an excess of aluminum foil then remove it once the reaction's done.
0. do not use iron/steel/cobalt/nickel tools that will be in contact with the copper sulfate crystals/copper powder. plastic spoons are recommended. for the hot parts, you could use a clean wooden stick - just anything that isn't a ferromagnetic metal
1. get some root killer (the blue copper sulfate crystals, CuSO4), dissolve it in DISTILLED water. you can try using hot/warm water to dissolve it faster
2. immerse aluminum foil (Al) in the blue solution.
3. add a pinch of table salt (NaCl) to start the precipitation reaction. the aluminum will dissolve, while the copper forms in the solution. THIS WILL GET HOT, so try wearing mittens or dilute the solution a bit with distilled water
4. the color should change from blue to cloudy brown. if it's still a bit blue, try adding a bit more aluminum foil and maybe a bit more table salt just in case.
CONT.

[Sunny No.15654485]

>>15654483
5. let the solution cool down a bit (so you can hold it), then filter with a coffee filter. wash with boiling hot distilled water to remove as much impurities as you can (so the soluble aluminum sulfate gets washed out).
if you do not care about wastewater volume, you can use like a liter of hot boiling water to wash out any remaining impurities.
(if it were me, i would also wash it with pure hydrochloric acid (HCl) BUT commercial hydrochloric acid is usually contaminated with iron (which is why they're yellowish), so i would advise against this - unless you want to also purify hydrochloric acid too.)
6. if you're planning to store the copper powder for a decent amount of time, store it immersed in clean distilled water in a sealed closed container - this is to prevent the copper from oxidizing into copper oxide (CuO). if you have some dry inert gas around, you could store dry copper powder with it so you can avoid the hassle of having to evaporate away the water.
7. if you're planning to use it right away, dry the moist copper powder. you can do this by leaving it out for a day or drying it in somewhere warm (maybe like around 100°C max).
8. just make sure the powder doesn't turn black. the problem with drying copper powder is that the longer you leave it exposed to air and the higher the temperature is, the more it'll "rust" into black copper oxide. i'm a bit concerned about contamination by aluminum, but i think this is the best we could do right away

[Sunny No.15654488]

>>15654485
>procedure:
1. Ensure you are working in a well-ventilated area and follow appropriate safety precautions, including wearing safety glasses and gloves.
2. Obtain matchboxes that contain striker strips. These strips typically contain red phosphorus.
3. Carefully remove the striker strips from the matchboxes using scissors or a knife. Take care not to damage or contaminate the strips during the removal process.
4. Grind the striker strips using a mortar and pestle or any suitable grinding apparatus. The goal is to break down the strips into a fine powder. Exercise caution during grinding, as the striker strips may contain other components that can be hazardous.
5. Transfer the ground material into a glass container or beaker.
6. Add distilled or deionized water to the container, covering the ground material. Stir the mixture thoroughly to help dissolve any soluble impurities.
7. Allow the mixture to settle for a while, allowing any insoluble impurities to settle at the bottom of the container.
8. Carefully decant or filter the liquid portion of the mixture into another container, leaving behind the settled impurities. You can use filter paper or a filter funnel to separate the liquid from the solids.
9. Repeat the decantation or filtration process as needed to further remove impurities.
10. If desired, you can evaporate the liquid portion using a heat source to concentrate the red phosphorus content. However, exercise extreme caution during this step, as phosphorus can be highly flammable and may ignite if not handled properly. It is recommended to use a fume hood or work in a well-ventilated area if you choose to evaporate the liquid.
11. Once the liquid has evaporated, you may be left with a residue containing red phosphorus. Handle this residue with care, as red phosphorus can be sensitive to friction and may ignite under certain conditions.

anon two last things
how is your safety setup and plan for the experiment, especially if SHTF?
what is your waste disposal plan? i know this is a bit annoying, but we're dealing with lead here.

the lead oxide part looks good; it's just that i do not recommend dealing with lead nitrate - it's the nitrogen dioxide fumes i'm concerned about. heating clean lead in air should be way more safer. in fact,
>Lead oxides are produced industrially by thermal processes in which lead is directly oxidized with air.
so you should be good to go. the purification part, that i don't know yet (i am tired and lazy, i am sorry). maybe try playing around with solubilities in different solvents.

Resistance
We need a 4 probe or kelvin probe measurement, i have seen in some other attempts to reproduce this that they use a small pcb board with 4 test points that gets soldered to the sample test. But it is not an easy solder job. It is probably the best way to get consistent meadurements.

Hi frens, sorry for the slow day. Been very busy with work. I have to go get some rest now. I already know tomorrow I will not have the time to begin cooking, and same for the day after tomorrow. I hope Monday we can start. Also I have bought online Cu and PbO of very high purity and trying to find a source for PbSO4 and P so I can have a control for my experiments. I’m very
curious to see how these lab made compounds react compared to the ones I will be making myself.

You will never be a real scientist.

You have no mind, no creativity, no Faustian spirit. Your worldview is entirely reductionist and materialistic. You cannot see the big picture.
You are a soulless bugman. A glorified office toady. You are afraid that your few petty comforts and your illusions of wisdom and status will be taken from you if you
don't toe the line. Your discoveries, if any,
will only be used to enslave humanity. You are a cog in the machine.

You are a slave to bureaucracy and credentialism. You can't do anything without permission. You spend more time on grant proposals, meetings, PowerPoint, citation butt-kissing and job hunting then you spend doing actual science.

You will never fly to the Moon in a spaceship that looks like a high school stage prop.
You will never scare the crap out of JP Morgan.
You will never make a nuclear reactor in your mom's shed.
You will never get the Spicy Ball.
You will never learn how consciousness creates reality.
You will never believe in science, magick and God at the same time.
You will never see beyond the veil.
You will never have a dream in which the Ouroboros serpent gives you the structure of benzene.
You will never accidentally discover LSD.
You will never realize that the internet needs to be decentralized while tripping on LSD.
You will never come up with the PCR process while tripping on LSD.
You will never blow the whistle on the worst genocide ever.

You wasted the best years of your life memorizing formulas you will never use. You are wasting the rest of your life on a treadmill to oblivion, chasing endless minutiae, and tweaking computer simulations that will never work because they were built on false assumptions. Most of your efforts will be lost or stolen.

You feel powerless. The only power you are allowed is try to silence and demoralize those who go against your masters. You do this for free, out of jealousy. You have fallen for the system's neatest trick.

This is a good way to test if it's a ferromagnet.
Cool it down through its transition temperature and see if it retains the field. A ferromagnet will. A superconductor will expel the field. A ferromagnet will also always be attracted to another magnet (possibly after re-orienting itself if it has retained a field) but a superconductor will try to maintain its position relative to a magnet.

chinese think they have achieved full levitation with their lk99 sample
TL;DR of the post, apparent full levitation achieved regardless of magnet pole and orientation (upright or upside-down). when the floating flake is pushed down, it bounces back to where it was floating originally.

>The first part of the video shows the pinning effect. The video shows that when the sample is pressed down several times, the sample immediately rebounds to near the original suspended position.

they will try to measure its resistance soon.
>Third watch: I am about to measure the resistance, and I am waiting for a new magnet.

also, the poster ranted about "unscientific people"

Did they just seal it under vacuum or was the reaction itself under vacuum? Obviously if you seal it under vacuum then you'll have a tighter seal but maybe it's not a big deal, if the reaction itself was under vacuum then yes, it might be necessary.

This is where things get tricky.
Yes, originally they said so. HOWEVER, they found just a few samples really worked well, and apaprently they had video recorded everything, so he went back and saw that for the sample that worked well, the quartz tube had cracked, admitting some air inside. This suggests some oxygen is needed.

So you might want to divide a batch into several tubes with different oxygen levels if you want to save time.

And when you have something that works, gently powederize the sameple and "destill" it over a magnet, then compact what levitated, and that way you have a known good sample for XRD analysis as well as demonstration. Make sure this process is ion an enclosed space so that powder of unknown toxicity doesn't get out.

Chatgpt says the following…
> To prepare copper phosphide (Cu3P), it is not necessary to vacuum the test tube. The synthesis of Cu3P typically involves a reaction between copper and phosphorus in a controlled environment.

[Sunny !!BIVeGb7hT6o No.15658842]

>>15658825
> You are correct, preventing the formation of oxides is crucial in the synthesis of copper phosphide (Cu3P). To achieve this, it is common practice to perform the reaction in an inert atmosphere, such as argon or nitrogen. By purging the test tube with an inert gas or creating a vacuum, you can minimize the presence of oxygen and moisture, which helps prevent the oxidation of copper during the reaction. Therefore, it is recommended to evacuate the test tube or use an inert gas environment to ensure the success of the Cu3P synthesis. I apologize for any confusion caused by my previous response.

You might be able to use a noble gas, but this is going to be fiddly and probably expensive. You could buy it by the tank at a welding supply store.

Nitrogen and carbon dioxide are fairly inert gases so maybe you can use them, or use oxygen absorbers. They are used for food storage. You should be able to buy a bunch of them cheap.

The goal is to get your Cu+P in one end of the sealed tube, and the oxygen absorber contents in the other end of the tube, with NO cross-contamination.

If using a quartz tube open on both ends, you can just shovel stuff in each end using small plastic spoons.

With a closed end test tube it's harder but can still be done. Use some tubing or a Slurpee straw or something to get the iron absorber MOST of the way into the bottom, deposit oxygen absorber, and deposit Cu+P into the other end using a small plastic spoon.

If this is too hard, try putting it into a smaller test tube, put a big test tube over it, flip upside down and withdraw the small tube without touching the walls of the big tube.

If your tube is not reusable, blowtorch the middle when the reaction is done, so that you separate the oxygen absorber before breaking the tube.

Oxygen absorbers contain iron powder, charcoal and salt. Obviously iron contamination would be bad.
You might be able to use a fragment of a car battery plate as an absorber. A little PbO in your sample is probably not going to hurt anything.

>>15658820
For the final synthesis you could start with a cheap option: use flowing nitrogen to displace oxygen. And during temperature rampdown you could add varying amounts of oxygen to the different samples.

Hard mode but also more interesting: use a heat proof 4 point probe and test resistivity during rampdown as a function of oxygen fraction in the gas flowing through the furnace. My hunch is that the right amount of oxygen will trigger a change that would be visible in the I V curve you trace out with the 4 point probe.

[Anonymous No.15658976]

>>15658916
using inert gases will run the risk of the inert gas itself diffusing into the CuP matrix and getting trapped especially so if the temperature is high and the powder having very small spaces between particles. very minute traces of inert gas could get locked in - assuming its a noble gas.

main reason is that mass transfer occurs due to some sort of gradient such as concentration. examples of diffusion are air diffusing through saran wrap slowly and helium diffusing out from rubber balloons.

>>15658916
nitrogen N2 and carbon dioxide CO2 at elevated temperatures are more likely to do unwanted reactions because of thermodynamic fuckery. for example, N2 reacts with O2 in lightning or in a car making NO2 gas.
if the inert gas route is to be tried, use the least reactive noble gas. the best should be Helium, followed by Neon and Argon. Argon should be the cheapest I think.
oh and fun fact, some noble gases can react and form compounds as you go down the periodic table.

[Anonymous No.15659095]

>>15658976
OK so it looks like these are the options, ranging from cheap and potentially sloppy to expensive and rigorous:

-Oxygen absorber (possibly DIY without carbon), but any oxygen absorber leaves a lot of N2 plus small amounts of O2, NO2, NO, CO2, CO, Ar and Ne. Some of these will get trapped in the sample. N2 and Ne are probably mostly harmless; the others not so much.

-Helium from the party supply store. Get the smallest possible leak to blow through the sample, let it run for a while to ensure it replaces all the air. Seal one end of the tube and get an assistant to shut off the helium AT THE SAME TIME. Then seal the other end of the tube. Some helium will get trapped in the sample but it is the least likely gas to do anything. However, party helium may not be pure helium. Likely contaminants are neon, oxygen, nitrogen, methane, carbon monoxide, and carbon dioxide. So might not be much of an advantage over oxygen absorbers.

-Buy vaccuum pump. 10^-3 Torr might be overkill; they probably had a great pump so they used it, but this is going to cost some money either way and probably preclude a lot of amateurs from doing the experiment.

Suggest helium first?

There are going to be contaminants in the phosphorus for sure. Hopefully they will bake off but they need somewhere to go. A thin stream of helium, or a vacuum, will have to carry them away as the sample bakes. So can't use helium+ vacuum at the same time unfortunately. Gonna need a copper gas line going into the kiln regardless. Going to need to angle grind a notch in the lid or use fiberglass insulation around the lid to keep it open a bit.

[Anonymous No.15659493]

Probably easiest to use helium because it won't matter as much if the seals are fucky.

[Anonymous No.15659501]

The helium will be cold when it comes out of the tank and needs to be hot when it goes in, so send it spiraling down, like in a still. Wind the pipe around something to make the spiral.

[Anonymous No.15659581]

>>15659501
Actually since the helium will be contaminated too, you will want to make sure there is so little helium that the amount of contaminants passing over the sample will be far less than the amount of air that was in the tube to begin with. Say you want 10-20 tubes of fairly pure helium over the course of the bake. No need to make the input tube a spiral. It will be perfectly hot when it goes in. Now the problem becomes making a hole or valve that will admit such a small flow. I think the way to do this is to have a secondary container that is near atmospheric pressure, like a bellows, and helium is released by slowly squeezing it. I think a water bottle in a vise would do fine. The helium output has to go down into the bottom of the kiln and out though a very small hole. This ensures that any off-gassing leaves the tube and does not return.

[Anonymous No.15659628]

why use gas displacement and risk all these problems. you don't have a $500 small electric vacuum pump? no big deal. use an old vacuum ejector. I don't know what's going on, but it sounds like the requirements for the vacuum aren't that important and the goal is more about sucking off

It's probably a lot higher than 10^-3 Torr. What could be achieved with a $500 pump?
I think it was mainly getting rid of SO2 and keeping oxygen out in the final step but that might not be necessary. But if they can get oxygen out of their other products they would have used it there too.
BTW helium output tube would not need to go out the bottom of the kiln.

How can one realistically probe a sample while being cooled down with homelab equipment?

[Anonymous No.15660430]

>>15660369
I don't think that is hard, you need 4 copper wires, and make sure these don't short circuit, for instance by using small ceramic beads around the wires.
One pair connect to the ends of the sample, the other in line around the middle. The only problem will be if you use a sealed evacuated quartz tube, but if you use flowing nitrogen gas you should have no problems.

just because some people are saying to electrically probe the rock does not mean it will work. the authors of the original paper did not mention probing the rocks for superconductivity. they used a thin film sample and the recipe for making it is not public.
there's nothing in this info that implies you should electrically measure the rock, and that it should show superconductivity, specifically for the baked rock.
you can try to measure it, but failing to get a superconductive result does not mean anything in the provided context. especially with the whole 1D superconductivity thing which further complicates matters (and measurements)

>just because some people are saying to electrically probe the rock does not mean it will work.
I didn't expect the material to be superconducting while in the furnace, but I do expect some conductivity. It was thesame for YBCO, in the normal state it had some conductivity.
>the authors of the original paper did not mention probing the rocks for superconductivity.
That is no reason to stop others from trying.
>they used a thin film sample and the recipe for making it is not public.
The papers including the patent applications published, had the receipe published in sufficient degree for others to attempt replication.
>there's nothing in this info that implies you should electrically measure the rock,
So? It doesn't say you shouldn't do it either. And research at this stage is all about trying variations, exploring possibilities and numerous dead ends. real research is not like a generic Star Trek episode where "drama" means that they haven't cooked up this weeks solution until 5 minutes before the credits are due to scroll.
>and that it should show superconductivity, specifically for the baked rock.
I do not expect that. What I expect is that the degree of oxygenation will change the conductivity.
>you can try to measure it, but failing to get a superconductive result does not mean anything in the provided context. especially with the whole 1D superconductivity thing which further complicates matters (and measurements)
I cannot see how that will change anything of what I proposed.

Research is about many things. Replication is important, but I am confident that the big labs have replicated according to the receipe with the utmost care and with more resources available than OP has. The other part is exploration. Exact replication does not give the big payoutr som now is the time to try variations. The old shake and bake route explores a huge parameter space which is good for those well equipped labs with robots that can make exact compositions with 10,000 variations. OP is not there, or he wouldn't have asked us. So I propose to take a very different route: explore the IV curves as a function of T and O2 for the bulk pellets. We don't know what the electrical properties is, but semiconductors have been mentioned so it is fair to assume we won't see a good insulator.

>you can try to electrically measure it. you can do whatever you want bro. I'm just sharing my thoughts on the subject.
Sure, we all do, anon. And I hope OP publishes some results, at the very least on viXra.

>>15668340
1. yes it might. since you actually need that, you'll have to use a magnet. just cover the magnet with say plastic or paper. i recommend an old neodymium magnet from a hard drive.

2. cardboard will cause carbon contamination (it's made of cellulose, so carbon, oxygen, and hydrogen primarily). no idea how to separate that from the red P. probably decantation or solvent that only dissolves cardboard? idk.

3. no need to rush. just take it slow. science takes time.
