That worked out quite well. Wonder if you'll see a spike in your power bill or meh.

This is the most informative channel I've come across with genuine quality and truthfulness that is helping thousands of hobbyists Great content Jake

Just love the authentic way you guys work stuff out, experiment, admit your mistakes, learn from them, try again. The subject matter is fascinating anyway. But your attitude and presentation make it compelling viewing.

"A Handbook of the Manufacture and Proof of Gunpowder as carried on at the Royal Gunpowder Factory, Waltham Abbey" (Capt FM Smith, RA) 1870, goes into some detail regarding the charcoal they used and how it was made. Variables they would consider include: The type of tree. The age at which it is cut down. The season in which it is cut down. The size to which it is cut for drying. The stacking method whilst drying. The length of time it is left to dry. The removal of knots, bark and foreign material. The size to which it is cut for burning. The length of the burn. The temperature of the burn. The length of time the resulting charcoal stands before being ground. The size to which the resulting charcoal is ground. All of these (and similar for all aspects of the powder making process) were highly regulated to ensure excellent quality, reliable and consistent gunpowder. These skills have, of course, now been largely lost!

Alright. Now, you are getting down to brass tacks. I believe there is more to the type of carbon used in Black powder as you have already demonstrated in previous videos. Firstly, what role do all three components play in ignition. What role does carbon play. Take the Cottonelle and balsa wood carbon, which has proven to be the best, and attempt to determine why they work so well. This might lead to something even better.

This is fantastic. I love watching normal people science. You don't have a high tech lab, or a million dollar budget, but you have a knack for explaing and a desire to teach. This sort of thing and experimental archeology (which this might fit) are some of my favorite content. (Still holding out for mushroom propellant)

This is great! I believe the point of controlled charring is to make charcoal that is undercooked to a certain degree. Charcoal made at lower temperatures for a limited time has chocolate to brown color, and it ignites at lower temp compared to fully charred stuff. I've read somewhere that at the pinnacle of black powder development, a certain grade of brown charcoal yielded the highest round velocities. To make brown charcoal, the process has to be terminated BEFORE smoking has ended. If it is taken to the no-smoke stage, I see no difference between controlled kiln and fireplace methods. In my experiments with convection baking oven I found that temperatures as low as 400F are enough to fully carbonize wood. Stopping the process at various time points allows obtaining various degrees of intermediate charring. Another variable to control is puck's specific gravity. In Russia there were two grades of hunting black powder: standard "regular" and higher grade "choice". "Choice" had lower specific gravity of 1.6 - 1.65 compared to 1.7 - 1.75 of "regular". A couple of technical suggestions. 1} Use thermostat so that you don't have to control temperature manually. 2) Light up the exhaust to flare pyrolysis gas and avoid smoke. Keep the good work!

Fellas, I first off want to say that I love your videos! They've been a big inspiration to me to get back into the pyrotechnic arts, which I hadn't touched since I was an amateur rocketeer as a teen. It had never occurred to me back then that the powder I made for my engines would work just as well in a muzzleloader until I saw your videos on doing just that. I followed your guide on pucking and granulating and tried it out with my dad, who only ever used Pyrodex. Big fun. These days, I use a cheap Amazon metal melting furnace for making charcoal. I just cut a piece of 2 inch steel pipe to the length of its crucible, welded a piece of plate to the bottom, and screw on a cap that I tapped for a compression fitting so I can run a smoke tube out the top of the furnace. It has a temperature controller that you can set and it will hold that particular temperature. You can buy same kind of controller as a module and add to it your kiln to get the same convenience and precise temperature control. Keep up the good work! I'm looking forward to seeing how the cottonwood and bamboo perform!

simply amazing Jake I agree with the previous comments. As Far as I am concerned you are the authority on Blackpowder keep up the good work mate ,

Best antique muzzleloading propellant channel on KZfaq! Thanks for the time and money you invest in this, and for sharing the results.

Another great video. Always lots of interesting information and experimentation. It will be interesting to see if this can achieve "Cottonelle" level performance.

Your quest for perfection is admirabl!

You know you can light that smoke and it will burn like a ptopane torch until the organic vapors burn off thern the flame will go out. Then the chsrcoal is ready. Thanks for the video.

My mind is activated towards science.

Been lookin forward to Cottonwood tests for a long time.

This channel has consistently provided the best info around on this subject,that alone makes it stand alone,but the quality of the comments have added so much to my powder production,thankyou so much.have still found thumb dia red popular,aged for 3 to 4 years ,at a low temp,still kind of brownish……not fully charred. makes the fastest and cleanest powder.this is a recipe from Workshop Reciepts. Circa 1864… best regards from nz

I love the blame game comedy you two had 🤣😂 This is gonna be some epic "Charcoal Files" stuff down the road.

I admire your dedication to improving the process of making black powder and your attention to being consistent and minimizing variables. You are the very definition of a scientist.

That's definitely a great way to get your carbon done. Thank you for sharing this enjoyable and informative video with us six stars brother

Nice. Your testing will be much more reliable. One small improvement would be to buy a PID controller kit with a type K thermocouple and solid state relay. They're fairly cheap and easy to set up. By the way you could have made this whole thing out of ceramic wool. For your temp range even off the shelf rockwool would work (I've seen people make aluminium casting furnaces with the stuff). Would have been much easier and cheaper to work with. Would still make for a decent lid.

Definitely a labor of love for black powder. 😉

It's great to see you working out challenges one at a time. With the phenomenal successes you've had already, it will be interesting to see what progress you can make with the fine, fine tuning.

Derrick spinning that variac knob like Marty McFly in the opening to Back to the Future. Even sounds the same....results the same too.... Rock n Roll from KY

Dang, I thought drilling a 2nd hole in the paint can lid and putting a lead thermometer in it and leaving it the whole time to monitor temperature and adjust gas grill accordingly was a breakthrough & cool: outdone again!!! Looked like a fun project, w a cool name and worked as designed. Well done once again!

I love your closing statement.

bricks are mostly pumice . volcanic ash .might want to get some ceramic wool to help insulate the lid

My wife has a ceramic kiln. It takes 6+ hours to get up to temp. Your kiln is working well. Takes twice as long to cool down since your rig is well insulated. I like your experiments. They are answering questions I have had for a long time. Thanks.

I appreciate your continuation of improving your method and sharing your results.

Entertaining and educational. Should not be this fun to watch. Keep up the pursuit of the best and people will want you to start a business of manufacturing it to sell

As always, it was interesting. I am really interested in how the cottonwood works. It was supposed to be the carbon source of choice (and necessity) of the Confederate States in the Civil War. As you know it is also available in quantity here in the Southwest.

This is awesome! I can't wait to see how it turns out.

Thank-You!

Love your videos

Well I guess the next logical step in this charcoal journey is to figure out the best temp and time to cook at. Thanks as always for the interesting videos.

Ty so much for bringing this passion back I look forward to checking this long right out soon

Can’t wait to see the next episode

Very good!

I own a heat treating company and build our high temp ovens. It was very smart to cage the bricks. As those bricks heat up and cool thy will crack. But if thy are constrained thy wont fall apart. If you have any questions about this let me know. I digitally control all my ovens with pid controllers. It’s a very easy set up and generally cheeper then a big varac

Excellent job Jake. 👍👌

Welcome to the club. You can expect 20%-45% volatile content by weight. I've not run this species in my lab so I don't know what you'll get. I suspect about 30% volatile content. You'll attain lower ignition temps, lower combustion temps and the higher volatile content offsets your fixed carbon and by way of this, offset the inert ash content which translates to more fuel by weight and less fouling. There's more chemistry involved too. A lot more. Like Ph.D worthy studies that one can venture into both in the charcoal and the powder made from it.

Outstanding

You guys do a great job at trying out new and inventive ways to make an old staple and I LOVE it! You give out great info, make good videos, and are not afraid to fail. Good on ya and great job!

You guys are getting higher precision all the time. And, two different materials for carbon source. Looking forward to next weeks video!

The smoke coming out is probably flammable. Lighting it with a match might get rid of it, just make sure there’s no way for fire to spread or for carbon monoxide to build up.

Well done Jake.

Awesome information. Thanks for the education.

Very clean charcoal! Excellent work! 🤠

Ok, close to what I want to see. This is what I want. The best TP, all the same batch. Real control of temperature, I suggest you insulate the box(fiberglass with foil wrap) and put in heat sinks (large steel bars in corners work well). Heat it up and run batches at a fixed temp in 15 minute intervals. I would particularly like to see it pre smoke stopping. Then mill and strain to a set size. Please?

Another brilliant piece of work! Thanks for sharing mate, cheers.

Cottenelle in the new kiln, please. Would love to see the performance. Thanks for all you do. By the way......I've never heard of her either.

Thank you for the new video Jake that looks like it ought to work real good cuz that was some beautiful looking charcoal

looks good hope it works

You are just great!

Maybe try a water trap on the exhaust? A length of hose to a bucket so that no air can be drawn back but it can exhaust.

Great idea. The charcoal looked good and uniform .

Have you thought about what your bp company will be called? Professor Jake, you do not disappoint! Thanks for another great video!

Fascinating stuff as usual! Very interesting to see what the best temperature ends up being.

Very cool

Really beautiful experiment. Can't wait to see the results. Hat's off to you.

Excellent work! This is why I subscribed.

Between ya'll and couple videos showing people building kit black powder rifle I got flintlock Hatfield 45 cal flintlock haven't shot it yet and haven't shot bp since early teens least this is a start ty guys God bless

WOW...again, lots of good usable information....great to watch and I am confident that you are going to nail this process also! Keep up this awesome testing!!

You should look into a PID and SSR to control the kiln/furnace. The PID turns the SSR (solid state relay) on and off to precisely control temperature. There is alot of info on setting them up with wiring diagrams online. You just have to make sure the SSR is rated for the amps of the heating element.

Interesting concept. It will be interesting to see how it works. Thanks for the video!

A month ago I wrote in a comment:.....Use a controlled carbonation temperature. And here it is.....😎..Great work boys. (The furnace could have been made from a small stainless steel beer keg. Filled with ceramic wool. Easy to carry and indestructible)

I can't wait to watch It. I love every one of your videos. You inspired me to buy a Kibler mountain rifle In 45 I loved it so much.I ordered a 36 caliber barrel and a 32 caliber barrel for it.Also thanks again.

That charcoals gonna be all that. Good job as usual gents. And thanks for the vid. EBP ROCKS!!!!

I'm excited to see how the cotton wood does. I actually got out my lyman flintlock out and got 8 rounds off before the ball got stuck. I hope I can make powder that can do better than the goex I was using.

Good video

Looking forward to seeing how the cotton wood works out.

Another great episode. This is a great application of the scientific method. I dub thee the energetic propellant scientist. Or garage scientist. Or BP Scientist.

Might be worth integrating a PID controller instead of the variac to keep the temperature more consistent. Johnny's Reloading Bench had a design intended for lead melting pots that could probably be fairly easily adapted.

You scienced the crap out of that wood. Looking forward to seeing the results.

2 hours is good as different materials may need longer than cottonwood, but the parameters should stay consistent. Cool video.

Awesome, can wait to see the results. A suggestion. You love the balsa based black powder. Why to do a head to head comparison?

Awesome kiln! I wouldn't have bothered with the variac. Just hook it up to a cheap on-off thermal controller and set required temp then let it do it's thing. You can even get em with time control so you can have it shut down after it is done cooking.

I'm following you on this. So far I've had to buy some 4" pvc + fittings, a v belt and one pulley, 40 1/2" balls (need more and bigger!😅). I'm in the process of milling ingredients and experimenting with the process. I have some experience with temperature and have many "artifacts" laying around as a result. I knew I'd find a use for it someday!

Well i tried something couple of years ago and it seemed that work nice , I don't know if i found the fountain of youth but it's kids of weird! So i cut down some branches of whipping willow , i clean the knobs and the bark from them and i put them in thick salt in airtight container and i left them 2 weeks in them! After i take them out the water and the juices from the branches was absorbed from salt and they had a huge amount of weight loss! After that i take them for Charing in my paint can (2kg capacity ) and i put it in metal fountry (working with natural gas) and i set the temperature at 350° Celsius, and it was ready in less than half hour ! The end product was brownish charcoal evenly cooked fluffy and very brittle, the results was astonishing ! It was so damn fast and it was burnt in paper towel so quickly that the towel look like almost brand new like it never had burnt from black powder! I said again i don't know if that was luck or i find the way of top performance black powder but it was so good! You can try it jake and upload a video to show us the results! Nice education video !!

I’ve been shooting blackpowder exclusively for the last few years and have been looking into making my own powder. (Cannot find it anywhere around here, pyrodex mostly and triple 7 IF you’re lucky). Love the videos and the presentation, very informative.

I'm digging those safety flip flops around the shop. I got a pair I wear when I'm splitting rich pine kindling with a machete.

This is getting very interesting indeed, i am very grateful for your always top content i have followed the coal making process and i was wondering if you have tried the aspen wood kind of resembles the balsa wood a little bit i think lots of it where i live i cant remember if you have done this. keep up the good work and thankyou for your effort.

I like this idea. It's like roasting steaks to certain standard.

Great video, as always. In my experience, the smoke during the pyrolisis can be avoided by lighting on fire the fumes, because they are quite flammable. They are composed usually of carbon monoxide (poison!), hydrogen and traces of methane.

well done

EBP: Wow! I are impressed! Seriously. Yer going 'all out' here to make the best 'muzzle loader propellent' and it is very interesting. Really looking forward to seeing the bamboo as if it works well that is an easy 'never ending' source.

That is written in my german books about explosives, chapter " Schwarzpulver" = Black powder..."the charcoal has to be brown instead black in order to have better performance ". Interesting!

I think basswood will make a good carbon source. Definitely give that a try. It's a light wood, not as light as balsa but lighter than pine. It's actually close to the light grain of the pine but way softer that the dark grain of pine. I'd gladly send you some if you have a PO box I can send it too. I use it for whittling 👍

I really enjoy all this testing and the attention to detail, science and consistency across the board. Its awesome. Keep up the great content. I am curious though. What do you do for work in your real life. I am a fish farmer. Raising hatchery trout for the Province in Alberta Canada. Thanks again.

Nice, been considering something similar. You could get another few bricks and lay them on top after you put on the metal and might speed up some more. ;)

That's hardcore!

You can power it up with a SSR based temperature controller and a k-typed thermocouple. It will be much easier to operate. Looking forward to see outcome of this test.

It’s like making your own still minus the moonshine LOL. Now you have antique propellent still. You did a great job Jake

Very nice! I think you could go for a tougher lid though, something like a frame holding a layer of those bricks would keep it cozy =)

I have and use a similar oven. I use mine for heat treatment of steel during knife making. I do have a question for you. I have used cooking pellets from my pellet smoker.specifically used the pitboss competition blend and it seems to be very consistent and clean shooting

it would be interesting to compare velocities using the same material for charcoal using old method vs new method. The amount of control you have now SHOULD result in a cleaner burn using the same carbon source material.

I like where this is going. Try running some rolls of cottonelle through the kiln at different temps and times to establish a performance baseline to compare all the rest? Be a bit of time and labor but worthwhile.

No suckyness detected. 👍I have a lost wax casting kiln that can be set up to 1100 F.. should work good for that.

Great video as usual. Wondering what the current use was? I might try this setup later in summer and capture total energy use for charcoal plus milling. Thanks again!!

Awesome stuff! If you put the same type of brick as lid, will be even better isolated

The process you describing is radical distillation and those fire bricks are made with it aluminum as well as other materials
