“Isn’t lye used to dissolve bodies?” - Lauren To answer your question Lauren... yes it can be used to dissolve bodies in high concentrations and to dissolve a whole human body you need an average of 5 gallons of a concentrated lye/ water solution

You can also make lye from woodash. Mix ash with water (preferably warm or hot water, but cold water and more time works as well), strain it to remove the ash, then you need to separate it from the lye. You can do part of the separation by letting it precipitate to the bottom, and the rest by boiling or simmering. After all the water is evaporated, you have lye without water. But for soap, you can use lye water in sufficiently-high concentrations. For cutting soap, a hot knife is preferred, but also more dangerous. Many cultures used the ash itself, as a powdered soap, for things which it didn't stain. Like washing yourself from head to toe, including teeth brushing, for example.
I was looking for this comment as this was the method of lye production I was more familiar with (and ergo the method I was expecting in the video). I also thought this was the older/more-traditional method comparatively.
@@Electracion It's also simpler, if you don't have a mine nearby, since, in the past, every household had ash, and they would sometimes even use it directly as soap, but sometimes they would boil it (into potash), strain the ash part, and mix the rest with cooking oil which went bad, and lard which went bad, or simply stored it as-is for later use, or even diluted it and used is as-is.
@SapioiT that is not lye thats potassium carbonate also known as potash to get hydroxides or lyes you need to fire certain compounds into oxide and mix them with water like in the video up. Even though you could make some soap with it you couldnt quite make a bar😢
It'd be interesting to see a re-evaluation of thr soaps after a month, as usually you have to let them cure for some time so that the remaining lye has had time to react.
I was coming to make the same comment! I made soap once with modern ingredients: lye and beef tallow, that you buy in the store. I certainly didn’t make anything from scratch, lol. But I do remember having to wrap the soap mold in a blanket and let it cure for 4 to 6 weeks before it was safe to touch according to the directions that came with the kit that I used.
I really love your videos and I learn quite a deal from them! This time I only have one think I would've liked to dee in more detail: After you bild the screw and everything for the oil press, you only ever showed the olives being crushed, never how the screw was being used :D But overall: Great work, keep it up, folks! :)
If I recall correctly, letting the soap cure for 1+ month would help neutralize all of the lye, making it safer to use. [Disclaimer: might be wrong on this.]
2-3 weeks will let the lye fully react assuming you have your ratio right. Most soap cures for 4-6 weeks though to release any free water and make the bar last longer.
Yes - typically, using modern ingredients, measurements and tools, then Yes the average curing time is 4 - 6 weeks, depending on the mixture of oils used, this curing allows for the quality of the soap to transform. Except that with 100% olive oil soap, originally called Castile, or Aleppo depending on the regional area how it's made, that curing process takes longer, typically 6 months to a year, or more, again depending on various factors. It can be used after the 6 weeks, but as with time, like wine and cheese, it gets better with age. The "oh it doesn't suds much" is because what most people are used to using, the store bought bars or liquid cleaning products that are now commonly used for washing dishes, clothes and your teeth, are technically detergents, (or include detergents) But are not actually "soap." - It's detergent in these products that suds up so much. - (Yes there's detergent in your toothpaste. Read the label and look up the ingredients.)... But because of the characteristics of olive oil in Soap, it is very LOW, if any sudsing, but still cleans. By actual definition true Castile Soap is only made with olive oil, and for Aleppo, laurel is added. Unfortunately many soap makers are taking liberties with the terms and adding other ingredients but still using the Castle name, because, in part, so many people are under the misunderstanding that sudsing is cleaning. Soap cleans, not suds. If your soap is actually soap, doesn't have detergents, but is sudsing, it's not 100 percent olive oil, or other things have been added to contribute to increased sudsing. Yay Soap…
Hey guys, love the series. Just wanted to note that there are far easier ways to make Lye then the one shown. One of the easiest I'm aware of it using Potash, which is just hard wood ash placed in a pot (Literally, Pot Ash) and steeped in rain water. The liquid lye will leach out and float to the top. It can then be decanted off and filtered into a separate container.
Old wood used on railroadd are treated with some not so healthy chemicals to prevent rot (cerosote and chromated copper arsenate), ideally it shouldn't be in enclosed space for obvious saftey reasons, stay safe out there.
Not only in Switzerland, in many European countries it is illegal to sell such spent ties to individuals. Creosote is both toxic and carcinogenic, this is basically a hazardous waste. I wonder what are the regulations in US.
I would've wanted to really see how you applied pressure on the olives with the screw, because in the sound clip, it sounded a bit... broke and I honestly can't imagine someone just screwing it in by hand, considering that in the photo you showed there was a square part to it in which you could fit a stick to get some leverage.
Right, it definitely didn't work. To make a corkscrew like that that would fit perfectly and spin smoothly would take a very skilled carver. They also didn't show them filtering or refining the olive oil in any way but magically it's pure when they use it to make the soap.
@@rontropics26 And as someone who's made soap before, insufficient stirring definitely wasn't why it didn't work. The reaction starts immediately irl. It was that the lye they made wasn't pure enough. Notice how at 11:56 the new lye looks very granular. I think they used store bought lye and olive oil for the second run.
@@rontropics26 sadly htme isnt trying anymore. Since the reboot Series with a Team of people the quality of the Videos dropped instantly.

Yeah, the current method is "if we [kinda] make it once, we can just buy tons of it from the store," and just skipping over a lot of the actual effort that goes into getting really pure ingredients and high quality tools. He didn't even bother trying to use the file he made from scratch, just opted for a store-bought one. Really feels like they're straying from the spirit of the venture...
This is the best soap video I’ve seen. And surprisingly I’ve seen a few. It helped me understand how the greasy stuff is turned into something that cleans grease. You also started with raw materials at the beginning which I’ve never seen before in a soap video. Love your content
I use my kitchen grease to make soap all the time in my crockpot. The reason the soap still had "blotches" of high PH is because soap usually takes several weeks to cure entirely. That is using my highly refined NaOH too so, it probably would take even longer with handmade lye.
For making soap, I've always added an excess of oil to make sure that the lye is all reacted and it's a lot better on your skin. And because theres soap it doesnt really matter if theres a little extra oil bc of the soap so it wont feel greasy at all. I think it's called overfatting
I've finally caught up on the videos in this series. I only recently found your channel, and have been binge watching lately. You've got some great content here mate, and you should be proud of it. Great stuff! I can't wait to see more. Thank you for the entertainment and education.
Yeah it's pretty dangerous. I had severe lye burns on my foot due to local home made soap I bought from some sheep farmers. I had some thin resedue on my foot and because of it being re hydrated by sweat and my feet touching I burned two parts badly.
2:35 your illustration shows "fatty alcohols", not "fatty acids" and the resulting molecules depicted as soap are actually alkoxides (which are only stable in the absence of water and react violently with moisture to form the corresponding alcohol and alkalihydroxide while generating heat). The difference is that in order for these to be fatty acid salts, the carbon binding to the Oxygen actually needs to bind to another oxygen atom using a double bond. Also, try making your lye from wood/plant ash! the main causic ingredient in it is "potassium hydroxide" and it leads to a much higher quality soap without the need of using limestone at all.
small suggestion with the new press, you may want to make a press basket for the center so you can press a larger volume at once. also, you could extend the catch spout out from the block so a container can be placed under the spout so you don't need the reed to guide the liquid.
I'm curious as to why they didn't go the wood ash route for lye. It might not be super effective at producing hard bars (beeswax can help with that) but its easy to make. Also, 100% olive oil soap can take months to cure properly, unless you use a hot process. I'd love to see an update on these soaps later.
Hang on, how were you actually using the screw? We didn’t see any sort of wheel or crank at the top for you to apply torque to the screw. Nor did we see it actually thread all the way down to apply pressure to the stack of crush olives.
The tap and die are still a ways off; carving the inverse of a hand carved thread would be very difficult with even modern tools. And that screw was far from straight. I'm guessing they took some artistic liberties with that part.
I assumed as much. I’d seen woodworkers make wooden nuts and bolts as a challenge, and it seemed difficult enough as is. When Andy first mentioned that he planned on making a screw, I was immediately a bit skeptical.
With such a wide thread the reverse won’t have to be exact. I would think a simple angled edge would provide all the power needed. I kind of like that they make these things from scratch and don’t hire professionals. It represents the struggle you and I would have to go thru if we had to provide for ourselves
Aren't railroad ties considered toxic by the EPA because of the creosote and other chemicals used to prevent rotting. I guess as long as it doesn't come into contact with the food directly it should be "ok". Look forward to the next video.
they're very toxic and not safe to handle, in my area people who try to use them for landscaping get in trouble because they're dangerous to handle so not allowed in residential areas. they can make you sick if you handle them barehanded, especially older ones from when they were a bit lazier with safety regulations.
@@lachlanngordon1577 from the cross section I saw I'm pretty sure that was a railroad tie soaked in creosote and even if it wasn't it would still preserved with chromated copper arsenate which is almost worse.
@@lachlanngordon1577 they've been using creosote on them almost as long as laying rail has existed, my gramma was warned as a kid never to play around with discarded track wood because it could make you sick, and even during the depression people living in coke ovens desperate for heating fuel would scrounge fallen coal off the tracks and burn furniture before touching rail wood, they knew it was poisonous to handle and burn.
As a chemistry student: The shown molecule of the soap is missing a double bonded oxygen atom next to the terminal negative charged oxygen atom. Simple soaps are fatty acids salts.
This is something obvious but I challange you to make bucket. You already are using iron tools but for bucket it would be challange, as iron is still fairly difficult to process. Therefore wooden bucket would be great starting point Qualities: - Can be cleaned, or quickly replaced - Waterproof (duhh) - Light (water will be heavy enough)
I've been making cold process soap for 5yrs now and this was an enjoyable video to watch. I like how you processed the basic materials. Have you tried making lye from wood ash yet?
Cut the cured soap the day after you’ve poured it. It will not crumble, the longer you wait the harder the bar gets. I’ve been making soap for 6 years.
They pussied out; Really, the commonest early soap was made from animal fat, so he should smell like the dripping tray from a sunday roast... but I guess they didn't have the guts to show THAT process, from scratch...
Pro Tip: Warmer temperatures speed up the chemical reaction a lot. When we did this in our Chemistry class, we mixed the lye and oil over a burner. In my opinion Nitrate fertilizers and soap were the most important inventions for country development. With Nitrate fertilizers fewer people were able to feed a higher ammount of people, making it possible to assign more workforce to other sectors, and the soap made sure they didnt die so quickly from disease.
11:57, Isn't that store bought chemicals? Is that why the second batch yielded better results? Does that mean the original sample is the only quality one can achieve with naturally collected materials?
The process of making soap requires oil, water and lye, plus mixing. Each oil has a molecular composition, chains, that react differently to the combination of lye and water. Olive oil takes a really long time for the immersion Process. The first attempt wasn't stirred long enough to completely incorporate the ingredients, which is why it separated. The 2nd attempt, stirring longer is what is required to get the mixture to end up being Soap, when using just olive oil. No store bought chemicals were used. They made the lye, the hard way.
Highlight of my day is watching Andy and Lauren! You guys rock! I’ve done a few of your projects from the Roman concrete to the bronze sword. Love watching your advice and processes!
@@ornessarhithfaeron3576 ... I wonder where you are getting your olive oil soap? In my experience, without any other additives, it should smell like soap. Unscented soap.
Fun fact - you can get lyme (a mixture of calcium and potasium chlorids) by simply burning hard wood and putting ashes into water. Once mixed and then left to sit, hydroxides stay dissolved in the water while all the debree falls down to the botom. Another fun fact, if you mix ashes with just enough water to create clay consistency, you can shape it like clay, then when left to dry and mature, calcium hydroxide binds with CO2 from the air, creating primitive concrete. For smaller amounds of materials, there is no need to mine anything. Ash from the cooking fire would do.
The high pH of the soap might have something to do with water-soluble compounds in the lavender. If you steep the lavender in warm oil and then filter it, you might be able to get most of the fragrance without the water-soluble compounds. At first I was going to suggest steeping the lavender in hot water and then discarding the water, but the oil soluble essential oils might leave with it, plus I think the flours could lose some of their color and wouldn't look very good.

they're very toxic and not safe to handle, in my area people who try to use them for landscaping get in trouble because they're dangerous to handle so not allowed in residential areas. they can make you sick if you handle them barehanded, especially older ones from when they were a bit lazier with safety regulations.
@@TheMichigami I hope they don't keep it around to long or at least replace it with something a bit safer
Older rail sleepers weren’t contaminated with creosote and so are able to be used
@@lachlanngordon1577 from the cross section I saw I'm pretty sure that was a railroad tie soaked in creosote and even if it wasn't it would still preserved with chromated copper arsenate which is almost worse.
@@lachlanngordon1577 they've been using creosote on them almost as long as laying rail has existed, my gramma was warned as a kid never to play around with discarded track wood because it could make you sick, and even during the depression people living in coke ovens desperate for heating fuel would scrounge fallen coal off the tracks and burn furniture before touching rail wood, they knew it was poisonous to handle and burn.
As a chemistry student: The shown molecule of the soap is missing a double bonded oxygen atom next to the terminal negative charged oxygen atom. Simple soaps are fatty acids salts.
I really like that you with modern tools check that what you made works
Andy's neighbors in Minneapolis be like: Margey, look what that boy is doin' now!
I always think about that lol
Wow i have always wanted to how soap is made!
That is amazing looking olive oil from your setup.
*In stone world, being sick is an game over*
*-dr. Stone*
This is something obvious but I challange you to make bucket.
You already are using iron tools but for bucket it would be challange, as iron is still fairly difficult to process.
Therefore wooden bucket would be great starting point
Qualities:
- Can be cleaned, or quickly replaced
- Waterproof (duhh)
- Light (water will be heavy enough)
Can't wait for them to build a hadron collider out of sticks and stones
Wooden and stone hedge....
I didn't expect the football to return
I've been making cold process soap for 5yrs now and this was an enjoyable video to watch. I like how you processed the basic materials. Have you tried making lye from wood ash yet?
That spoon grinding on the bowl made my nails curl.
this is a really good series
I can't wait for the episode when he surpasses modern civilization and builds a robot or a flying car or something
"in a primitive world with out doctors soap is a lifesaver, you can call it Dr. Stone"
Since this was posted 4 minuites ago, no one has seen the end of the video yet.
I think the patreons get to see it earlier. Not sure though.
You forgot about the time difference haha
Im glad I discovered this channel, very interesting niche high quality content
Cut the cured soap the day after you’ve poured it. It will not crumble, the longer you wait the harder the bar gets. I’ve been making soap for 6 years.
Her: "Ew you smell like vinegar!"
Me: "No, actually its Olives"
They pussied out; Really, the commonest early soap was made from animal fat, so he should smell like the dripping tray from a sunday roast... but I guess they didn't have the guts to show THAT process, from scratch...
@@baconsarny-geddon8298 tallow and lard (boil refined beef or pig fat) doesnt actually smell like cooked meat. Doesnt taste like it either.
tallow smells like a really tasty soup with a bit of butter on the side, and lard does indeed smell really strong and it's an acquired taste of sorts
Forbidden SOUP has become forbidden CUSTARD
you do what i only deamed of. you are an inspiration. i want to try making this soap. i have coconut oil on hand to use.
Instead of hitting the olive w the pestle put the pestle on the olive and hit it with wood or another object :)
I can’t get enough of watching this
Caveman chemistry, now that would be a channel I'd watch
Love the work! It is inspiring me in my worldbuilding. Thanks!
Like for stories or games or making things in real life in a recreation area?
@@hotaru8309 wrighting and games. Amongst other things i am a DM in a time travel campaign. (The players like going WAY back)
Pro Tip: Warmer temperatures speed up the chemical reaction a lot. When we did this in our Chemistry class, we mixed the lye and oil over a burner.
In my opinion Nitrate fertilizers and soap were the most important inventions for country development. With Nitrate fertilizers fewer people were able to feed a higher ammount of people, making it possible to assign more workforce to other sectors, and the soap made sure they didnt die so quickly from disease.
What about sea water desalination history ? Or history of turning desert in to oasis ? I would like to see it.
Most underrated channel
Did the screw press actually work? Or did the screw snap?
Also, was a blender used with the soap?
you could have boiled rain water and wood ash to make lye
11:57, Isn't that store bought chemicals? Is that why the second batch yielded better results? Does that mean the original sample is the only quality one can achieve with naturally collected materials?
The process of making soap requires oil, water and lye, plus mixing. Each oil has a molecular composition, chains, that react differently to the combination of lye and water. Olive oil takes a really long time for the immersion Process. The first attempt wasn't stirred long enough to completely incorporate the ingredients, which is why it separated. The 2nd attempt, stirring longer is what is required to get the mixture to end up being Soap, when using just olive oil. No store bought chemicals were used. They made the lye, the hard way.
Very cool! Love this series
Highlight of my day is watching Andy and Lauren! You guys rock! I’ve done a few of your projects from the Roman concrete to the bronze sword. Love watching your advice and processes!
4:26 you could've extracted some phenolphtalein from red cabbage. That might make a nice video actually
This is a great channel keep them coming. thank you
Yay, finally the screw!
One thing you didn't touch on, did the soap smell olive-y or lavendery or not at all?
.
From my experience with olive-based soaps, they do smell like olives a bit, but it's more subtle. So it should smell like a subtle mix of both.
It smelled really good!!! Very lavendery
@@ornessarhithfaeron3576 ... I wonder where you are getting your olive oil soap? In my experience, without any other additives, it should smell like soap. Unscented soap.
Episode 500: today we invented time travel !
Awesome I have always wanted to try something like making soap they old fashioned way 🧼🧼🧼
man i love this idk why
most underated channel
I would love to see you tackle dried and salted meat. Is ancient dried meat just like beef jerky or is it sucky?
Lauren is so adorably self-conscious, it's very fun to watch, haha!
This is a compliment.
Creepy
Ah those good ol viking age rail road ties 😆🤣
Olives, olive oil, and olive wood can have a similar effect to catnip. Probably why bill likes it so much
Now invent the shower and then let Andy test all the soaps with it.
I'd rather have Lauren do it, but whatever boils your cockles
Building a mini aqueduct would actually be a legit next step in their timeline.
@@wolffang489 Plumbing pipes were invented about 1200 years before soap so it would actually be a bit of a regression.
Love Lauren's accent
Lol I never realized I have an accent
Can't wait for the next episode
Fun fact - you can get lyme (a mixture of calcium and potasium chlorids) by simply burning hard wood and putting ashes into water. Once mixed and then left to sit, hydroxides stay dissolved in the water while all the debree falls down to the botom.
Another fun fact, if you mix ashes with just enough water to create clay consistency, you can shape it like clay, then when left to dry and mature, calcium hydroxide binds with CO2 from the air, creating primitive concrete. For smaller amounds of materials, there is no need to mine anything. Ash from the cooking fire would do.
his raftsmen ship has improved over the years
Would love to see you try and do some meat preservation.
You're really nailing the reset. Great work.
Absolutely love this show! ❤
Lauren: "Don't breathe in the fumes"
Also Lauren: [leaves face uncovered]
IF ONLY WE ALL HAD ACCESS TO MASKS THESE DAYS!
She's either sick of wearing one all of the time or realizes that it would take a charcoal respirator to filter out the fumes.
Really interesting stuff
Now create a record player to decode the glass disk your father left behind on his gravestone
5:30 That's my country!!
How do you think this process would be different if you obtained olives straight from an olive tree and that have not been brined?
This is what I was hoping to find.
I get so excited when I see you made a new video!
Nice! You unlocked tenon and mortise!
Aww the cat with the neckerchief Bill :)
The high pH of the soap might have something to do with water-soluble compounds in the lavender. If you steep the lavender in warm oil and then filter it, you might be able to get most of the fragrance without the water-soluble compounds. At first I was going to suggest steeping the lavender in hot water and then discarding the water, but the oil soluble essential oils might leave with it, plus I think the flours could lose some of their color and wouldn't look very good.
Can't lye be made by boiling wood ash?
