I've been in your place before. I tried the exact same method (except the wood used ) but I didn't get anywhere. I did some testing and finally managed to do it after making several changes: 1) I made a grate in the middle of the kiln on top of which I put alternating layers of wood and shells (shells were not placed in container and were just thrown in). 2) I started the fire from the top of the kiln 3) I reacted the shells with water right after the fire was settling down. Sadly, I don't have any scientific knowledge on why my method worked but I hope I could be of help. Thank you for making videos and inspiring this community!

@@ChadZuberAdventures No I left that area empty for the air to flow. Another thing I would advise is it run the fire for about 1 hour and 30 minutes maybe even 2 hours ,if there is enough wood around, to make sure the shells get calcined thoroughly. I was faced with that same frustration as you are for a long time, as all things primitive it's a rocky road. It's up to us , humans , to eventually fight beyond those roadblocks and use the laws of this world for our needs

So me and a buddy have made primitive quicklime which we used for concrete twice but we've only used wood ash to do so. As far as I know there should be no practical difference if you use ash or shells but do keep that in mind. I noticed a few things I'd improve. Before I list those I want to front them with a warning - DO NOT handle your shells with bare hands after firing! Your hands have moisture and chemical burns are nasty which will ruin your working day!. Learned that one the hard way by loosing a whole weekend of possible work due to massive chemical burns. 1. Get your fire off the ground. Make some sort of a grate or just 3-4 clay bars that you can put your fire on top. This will make a world of difference. This does mean you will need something to hold the pot, but we just used two big rocks for that one. 2. Fire for a bit longer. In our experience we fired for 1.5 hours but less might still work. If you can fire for 1.5 hours do that for your first win and then experiment and adjust. 3. Blocking your chimney a bit will help keep temperature in. If you have some big bricks or tiles prepared for something you can use those. We didn't have to do that but our chimney had a way smaller diameter and was tapered towards the top. I will also go contrary to something that has been suggested which is using charcoal. In order to properly use charcoal with your setup you need a blower of some sort and if you have a blower you don't need charcoal for this to work. Save your charcoal if you ever want to get your hands dirty with metallurgy - this trip I haven't taken. Looking forward to the next video where you crush the quicklime process! And remember don't handle with bare hands! I cannot stress this enough it's really nasty.

Thank you so much for this detailed account of your experience. Don't worry, when I shot the video I had already tested a shell the night before. I used stick tongs to pull it out of the ashes and put it in water. So I already knew that the experiment failed. Plus, the shells didn't turn white. It was clear it didn't work. But that is a good point that I should have put in the video. But I'm used to getting injured all the time anyway. Actually, getting injured by handling quicklime would make for a better video anyway, right? Hahaha!... I'm going to do your suggestions. I'm surprised that you don't think the charcoal is a good idea. I really don't have an opinion on that since I've never used charcoal before but you're the first one to remark contrary to charcoal. Most of the examples I've seen online didn't use a blower. In one attempt I did use a blower and it didn't work either. I really appreciate your suggestions and I will definitely be trying them out.

If it works, the burnt material will be noticeably lighter than the pre-burn material. It does work with shells. Keep trying! with enough heat and time, you'll get there!

Off topic, have you considered weaving a gill net that you could stretch across the stream at a narrow area? Passive fishing might be the way to go. Also, I’ve seen how ancient desert peoples in the Middle East used to carve cisterns into the rock floors for collection. I’m sure that’s really difficult to do, but have you considered some type of rainwater collection device?

Welcome to my channel! Yes, I'm sure I need more heat. Easily said, huh? And to let it cook more time. Yeah, I want to make a bigger net for fishing. It's all a matter of time. Weaving a fishing net does take an immensely long time. Carving cisterns in the rock here would be quite a big job. I haven't tried but it wouldn't be easy. I do have other ideas for collecting water. One is to build a dam in the wash with rock and clay. The other is to make several large clay water containers and have funnels to catch and direct the rainwater into them.

A very interesting video about natural life is happening here, people can live independently out there but still need the help of others to be able to survive, but not with my friend, this is truly an extraordinary struggle for life, everything she uses for her daily survival from nature is truly extraordinary. 👍

Another way to stabilize the pH of the soil: In a container with enough water, put the white ash produced by your oven and fireplace, stir very well and then let it settle, then remove only the liquid and let it boil until it evaporates, you will obtain potassium carbonate, a pH stabilizer that can also be used to make natural soap. You will need a lot of ash, you can use the liquid without boiling too and even add the ash to the soil without any additional procedure

I've seen that video and almost all his videos, as well as several other channels that did videos on this subject. I believe that there are two likely mistakes I made. One, using this kiln which was designed for firing pottery. Two, not burning the shells long enough.

This episode with the quicklime got me Dr.Stone vibes.

based on the color of the shells when you pulled them out of the kiln, you didnt reach the calcification temperature, but was very close to it. I recommend a blower/fan/bamboo blowpipe to force more air into the kiln to raise the temp. A tile or clay kiln cap with narrower chimney can also help with retaining heat inside the kiln instead of losing it straight out the top. My experience has been entirely temperature instead of time baking in order to get the reaction to make the calcium carbonate convert to calcium oxide.

Ok. Two problems that come to mind are kiln insulation and air intake; if the kiln had more mass (as in the walls were thicker, either with an insulator like ash or just plain mud with grass) then it'd retain more heat, and focus it in the interior. That talked about, air intake could also be a problem: as more air comes in, more combustion happens, therefore more heat is produced. A bellow or small rotatory fan (check Primitive Technology's multiblade blower) could work to focus more oxygen into the fire. Btw, for future tries on making calcium oxide, there's another source more available to you: bark. Or, more specifically, ashes from tree bark. The theory is that the bark concentrates calcium oxide (the wood does also, but the bark specially) from the soil, so, if you burn it, and then calcinate the ashes (you could make small balls of ash so that they are a bit more maneuverable) you get calcium oxide. Add water, and blam: calcium hydroxide.

2:26 While I am not a chemist, by any stretch of the imagination, This scene here reminds me of John Plant's experimentations in much the same processes, albeit he is making Iron, however, when using wood to create high temperatures, you have to use a LOT of fuel to get there. I think you simply don't have enough fuel to get to temp, much less stay there at that temp. John has made clay housed human powered fans and a blower apparatus, and uses charcoal rather than raw wood. My two cents only, take it for what you will Chad.

the compost looks very rich, either way. white wood ash should suffice for lowering ph. if you're set on using the shells, maybe a narrower but taller or longer furnace with a smaller inlet and chimney would get hotter as it'd "force" air more aggressively and make a stronger draft. thicker walls would also would help retain more heat. you could also try using the charcoal you made through incomplete combustion by starting a fire and smothering it with dirt as fuel; you'd probably start a fire as normal with whatever wood then feed it as much charcoal as you can while gauging the heat by look/feel through the inlet. i'm not 100% certain on any of this, but i hope it gives you some ideas.

Hi, I really like your videos, they are very inspiring (thanks for your content). what you are trying to do is probably the decomposition of molecules into atoms such as: sodium, potassium, calcium, magnesium, beryllium, lithium. these are elements with a very low electronegativity (very few valence electrons), oxygen has a high electronegativity, oxygen with the listed atoms (sodium...), forms very strong bonds so you need a very high temperature for decomposition to occur, you need to create a constant temperature of at least 850- 1000+ degrees celsius maybe for more than 20 minutes maybe several hours. if I can recommend a video for inspiration, it's called >PRIMITIVE FIRE SCIENCE! Burning Shells Into Lime In a Grass Straw & Clay Furnace

If it had worked a thermal reaction would have happened when you touched quicklime with your unprotected fingers, use gloves if you're going to handle quicklime. The lime in the burnt, ground shells would have been available to plant roots just at a far slower rate than you were hoping. To get quicklime from shells you'd need to close your kiln in (it's only really a chimney at the moment). Give it a small chimney and a door. Pack your wood in as densely as you can but leaving enough air for it to still light. Fire it fully and keep stoking it until the core remains white hot for an hour or so. Then close down both the door and the chimney and leave it to cook for a day or so. When cool rake it out but keep you skin away from it until it is fully slaked.

a furnace would be a good start. add fuel into a lower area, and have a grate to hold the shells above the flames. this lets you cook them for longer. adding height to the furnace to allow more air to be drawn through the fuel for a hotter fire, would be the next step. if you still cant get them hot enough for long enough, charcoal is the next step. burns far hotter than any wood you would add. anything more, means forced air.

From the brittleness of the shells at the end you're probably close. I'm not an expert just a gal on the internet that likes to learn.

The layers should be pretty even. 3) BIG MAYBE your kiln and the bottom opening that may be too big. Try using a shorter, more narrow kiln. A narrower space with allow the burning material to be stacked more evenly. The amount of space in your current kiln and the large pieces of wood used means the layering doesn't really happen because the gaps of space are too big so the shells just fell onto the floor. A narrower kiln may also help with temperature control and adding extra wood from the top as needed. You can actually build a quick version of a kiln by soaking long grasses in clay mud and stacking the soaked bundled to form a chute with an opening at the top and a small opening for airflow at the bottom.

@@ChadZuberAdventures I imagine the solution could also be thicker walls, perhaps a double-walled kiln with wood ash filling the dead space, and once the fuel is burnt, cover the whole thing with more ashes to let it cool as slowly as possible. I will admit that the only successful calcination I personally have done was in a small electric test kiln, and the various test pieces were kept yellow-hot for more than an hour if memory serves (we thought the cone hadn't melted, but it had actually turned into a pool of liquid and I don't know what we were looking at instead).

I'm no expert in primitive tech nor chemistry. You do need high temps, an article I saw said 900ºC (~1650ºF). I was curious whether a reducing atmosphere would help but apparently it's just a thermal decomposition. Given this is a heat problem not a chemical one; I think a taller chimney would help keep the heat in and pull more oxygen through. I'd also suggest making the intake/exhaust smaller because at the moment there is a huge oxygen supply that may exceed the furnace's capacity and cool everything down. That's my armchair prim tech hypothesis. I hope I'm right and it helps.

you can change soil ph with adding eggshells and such left in sun to dry then crushed up just ask friends to save them for you and it safer you should added warning on dangers of quicklime, also dont forget to add seaweed if able to as it very good for soil also bones from animals left to dry in sun then smashed with a rock

​@@ChadZuberAdventures with a kiln that big you want control. The top lid controlling how hot it stays and the bottom controlling how hot it can get. Like a stovetop, max heat isnt always the best setting. being able to turn a wood fire kiln into an oven has it advantages too. Slow cook things overnight while keeping animals out. Also effectively becomes an emergency shutoff in case some big winds decide to try and burn everything down. More directed towards the quicklime though, a setup like yours should be able to reach 800 internal within about 40-60 minutes but theres a lot of factors in that. Ive also heard of people using warm water in that final step but i have no idea if it matters or not but i do know the longer you submerge it the better quality you get. As a sidenote, be careful, hell break protocol with a pair of safety glasses or goggles. Quicklime can destroy your vision permanently if not force your entire eyeball to be removed. As far as medical is concerned, an eye burn is the worst possible injury. one bad splash is all it takes.

Considering where you live, the soil is probably already alkaline. Its always a good idea to test the ph before changing it, because plants can be very sensitive to ph changes. Wood ash itself is alkaline by the way, so you could make the soil drastically more alkaline without even considering quicklime. There is also "primitive" ways to test ph, like using hydangea or spiderwort color changes, it's just less accurate than a modern ph test.

@Garjahn

Ай бұрын

That said, if you're deadset on making quicklime from shells, i think it's important to keep your heat both high and focused. Hardwood or not, it's always going to be full of volatile organics that will burn off and lower the temperature of your flame. If you're trying to reach 800C and that's the maximum temperature of your wood, then your wood has to burn at it's maximum temperature to achieve the desired effect. However, if you're burning charcoal at 1,100C, then it only needs to reach 80% of it's maximum to do what you want. That's more ideal since you don't have forced air. The second issue is the size of your furnace, which is quite large for such a small pot of shells. there's lots of room for air to flow in and around the shells, keeping them from heating up. A smaller furnace stocked with charcoal would keep your heat much higher and more concentrated, allowing the shells to calcify.

@Garjahn

Ай бұрын

You can also try creating a lid for the current kiln and stuff the burn chamber with bricks to reduce inner diameter. You lose a lot of radiant heat to the sky with the top open like that anyways. You can try finding or making your own clay by slaking soil or clay with water to remove sand and rocks. By mixing in boiled starches, fine fibers and charcoal dust you can create a malleable clay and bricks capable of withstanding heat without cracking.

This is great information. Thanks so much for sharing. I've never made charcoal for burning so I'll have to learn that first. I always thought that good airflow was needed to produce a lot of heat but you (and several others) have suggested that I reduce the size of the opening at the top. I was not aware of this. Perhaps I will make a smaller kiln and shape it like a cone. Do you think that will work better?

@Garjahn

Ай бұрын

@@ChadZuberAdventures If the opening at the top is too small it will in fact reduce the temperature as the exhaust gasses still need somewhere to go, and you also won't be able to easily add charcoal or remove items from the top. If you're fine with that then it shouldn't be an issue. You might also consider drilling finger-sized holes in the wet mud or bricks around the base to ensure the fire gets oxygen and burns evenly, as having only one opening means it's only burning from one side. You can make charcoal easily by starting a small fire in a pit and then stacking wood tightly on top of it to remove as many air gaps as possible. Once it's burned down to a bed of coals, just put it out with water and spread it out to dry. I know making bricks takes you a long time and water is a pain to move, so this method will waste a bit more wood but it's also more convenient than building a charcoal kiln.

Manzanita wood burns significantly hotter because it is very dense. Juniper wood burns noticeably less hot. But I believe that if I do it right juniper wood will work.

Pure speculation here: 1. Charcoal 2. Insulation 3. Air 1. Higher temperatures. To make charcoal the Australian guy lays a pyramid of sticks, each floor comprised of parallel sticks, parallel to the ground, and each floor turned 90 degrees around the vertical axis and over the adjacent floors below and above. Not sure he also covers the pyramid walls in mud. Then lights the top and waits for it to burn all the way down. I think low air is what creates charcoal. 2. Keep the heat in. One of the commenters mentioned suspending the fire away from the ground. I think higher kilns get hotter too. Look at the amount of flames coming out the top of yours. Maybe it's wasted heat. I would suspend the fire as suggested and even make an inner thin wall of about 1-2 fingers, 1-2 fingers away from the outer walls. Air insulates better than solids, so this setup should reduce heat loss significantly. Make the kiln as high as you can and cover the top and leave only a small gap for gas exhaustion. Besides aiding insulation it may help the air to build up in the chamber slightly increasing pressure and maximizing air contact. Then again it may also do the same for combustion gases but well... I think calcium carbonate needs CO2 to convert to CaO, no? [edit: nope. it releases CO2 to convert to CaO] It may help. 3. Higher temperature again. Make a bellow with your deer(?) skin. Maybe make a clay pout or get a trim of your blowing cane. Sew the skin with cordage into a (palm size) bag, tie around pout, sew a couple strings each to each side, enter palms press and pull? I don't know if this would work but seems simpler than a hinge mechanism. The Australian guy is experimenting with fans. I would make a fan with those yuca leaves or something wider as propellers and I'd adapt it to a pottery/sharpening wheel kind of pedaling system. That would put out a shitload of strength and air. It's involved but it should be simple enough to be doable. Either ways cover everything in the bottom except the air inlet. Best luck, thanks for your work and I'd be most most glad if you implemented any of what I mentioned. PS: have you considered piping the water from the river home? Cattails? Clay pipes? I think it's a great challenge but it's for the ultimate comfort! It could eventually turn into a filter and boiler system to enjoy safe and hot water. PS2: advanced materials for advanced objects? Latex (rubber) from dandelions (there must be some in there)? Resin from any trees around? You could make elastic tools/weapons/utensils or line the floor and walls for a cleaner surface. I'm not sure where you stand with animals. Have you consider trapping and raising some for eggs, milk or meat?

Great ideas there. Thanks for sharing. The river is way too far for pumping water. All the other ideas are great.

I have no idea about making quicklime but I will recommend for you to watch "Edwardian Farm". Near the end of the first episode, they burn lime to create quicklime for changing the soil acidity. However, they accomplish this on a much larger scale than what you are doing.

Hi Chad. Youre close but your Fires too short duration to convert the calcium in the shells into calcium oxide. I recommend washing the shells in fresh water, to remove any salt residue or leave them out in a good rain. let them dry and then fire them for at least several hours. Your efforts arent wasted though the dessicated shells are a great addition to your compost. If you can find limestone, im not sure what the geology is in the area, but if you have it, id recommend that for converting into quicklime, fist sized rocks and alternate layers fuel,lime,fuel,lime,etc until you fill that kiln. It takes a lot of heat over a long period but has been done successfully for hundreds of years with firewood and shell. If you only have shell, clam is a great choice, youll need a lot of shells, buckets of them, to charge the kiln. Youll find a full charge of fuel and shell will convert more successfully but some will fail to convert to calcium oxide no matter how careful you are. Its a long hot process im afraid.😬😆.

If you alternate a layer of wood, layer of shell,etc that manzanita wood will produce a great result 👋👍

the research is a bit spotty, but I Think, assuming insufficient heat is the problem, you should probably convert the wood to charcoal. once source was saying that charcoal can easily burn over 1100c where as normal wood is only around 600c. whether that's true at all, or true for a specific kind of wood, I don't know, but it's generally accepted that charcoal is hotter. another thought is to use a crossdraft kiln or downdraft, to isolate the shells from the wood ash.

quicklime is useful for many things of course, but id say the ground shells are more or less equivalent as far as the soil is concerned; just not as fast-acting. But if finely ground into a powder like this, excess acid will react with the carbonate, liberating the co2 in the process chemically, rather than with heat; which gets you to the same end point. Arguably to a better end point since its self-limiting. With the quicklime you can create very alkaline pockets in your soil if you overdo it whereas the chemical process will come to a halt at neutral ph.
