@@168Diplomat I don't know why my answer was deleted. Is it because I referred to my channel where I show hot tent camping? Anyways, I do hot camping a lot, it's my favorite winter activity.
I was told by my Sgt Major many,many years ago that the reason Heximine gives off such noxious, smelly fumes is that when Heximine was first being used in the Korean War it was unscented and because of the extremely cold weather troops were using their cookers inside their dugouts. This resulted in carbon monoxide poisoning of those in the dugout. That's why the infamous smell was added , as a safety factor.
Interesting. I made the mistake of trying to make some coffee in my pup-tent with trioxane tabs when I was in the Army. It had a very similar affect as CS. Burning nostrils and eyes! Never made that mistake again. I have also seen soldiers burn themselves by picking up a burning tad. The flame is nearly invisible.
I think that fishy smell is a property of any hexamine fuel tablet. Old Soviet and new Russian-made tablets smells the same. No additional odorant needed. :) And yes, DO NOT burn hexamine (or any fuel at all) in a closed volume of air.
That smell of hexamine is a property of it. I have access to ultrapure hexamine and it just smells like rotten fish, not very strong of a smell however in its pure form. I make my own hexamine fuel tabs and they are only tad bit less smelly than commercial. Both of them still let out very toxic gases however

I just did the dried egg shell and vinegar method to make calcium acetate...now I just need to filter it, and boil it down to about 1/2 volume then mix with some alcohol! I ended up making 9 dz eggs for pickled eggs, took shells put on cookie sheet in oven set to lowest temp it would run for a few hours...then put shells in "the bullet" and powdered them...25gr powdered shells per 100ml of 5% vinegar(I actually doubled it)...let foaming stop, filter...boil down to 1/2 volume...then mix alcohol straight into the liquid...instant gelled alcohol :)
Great recipe! I use Coghlans fuel tabs which don't have the fumes of the Esbit tabs. But in the tent, I use tea candles. I've added aluminum reflector plates to fill in the side gaps of my folding Esbit stove to reduce wind and keep heat under cooking pan. Peace
I use Coghlan's fuel tabs, they are top notch, especially for the price! I've never tried to cook with tea candles. I will have to give it a try. Thanks for sharing the tip!
Home depot has 30% vinegar, and the feed store has crushed oyster shells. This stuff comes out so concentrated, crystals grow everywhere! Doing it right now👍

I imagine that spreading the fuel over the bottom of the Altoids tin would even out the heat and also minimize the unburned fuel. It could be interesting to do a side-by-side comparison of this product and the Perlite version.
spreading the fuel out will minimize unburnt fuel but also shorten burn time so you will need to use slightly more fuel to account for the larger surface area
Question The burnt ash - can it be mixed with alcohol and reused again for round 2 ? OK not sure how my question matched up with your answer . That is cool. Mix the ash with white vineger and the recipe for round 2.

Mixing the calcium with white vinegar (instead of water) and then boiling off about half of the residual volume (water content), this makes calcium acetate, before adding the alcohol, will give a better mix. Also, plain white chalk will be almost pure calcium carbonate, and is easily crushed in a mortar, or you can dissolve limestone in the vinegar to make the calcium acetate.
I suggest that if you think the older fuel is too loose, you might be able to tighten it up by adding more Calcium Acetate. You would have to experiment as to the proper amount because it's augmenting already produced fuel but it should firm it up.
"...That's the Berries" I'm gonna borrow that! Also, I think lastic might be better than mason jar lids on this one. I would be worried about rust. Great recipe! Thank you. Seems like with 2 heaping tablespoons you can really cook an egg and a can of soup. That's amazing.

You can also get glass mason jar lids. They have a metal screw, that can often be removed when your food is vacuum sealed, but should stay on in this case.
Shortcut to this, grind some egg shells, mix them with vinegar, wait for it to bubble up, strain through a coffee filter. There you have it, calcium acetate + water. Then mix in the alcohol, preferably food grade ethyl alcohol so it's non toxic.

l love it ! . im glad i stumbled across your channel . im saving this one lol . being i make alcohol now and then its a perfect combo . thanks for sharing take care
Interesting. Thanks for demo'ing the gelled alcohol method. I don't believe you ever stated WHY one would prefer gelled alcohol. In my backcountry experience, typically at 10,000 ft ASL, I get 12 oz of water to boil w/ just straight denatured alcohol in 10 minutes... which is how long the alcohol lasts, coincidentally. So why gel? Does it carry well in the backcountry, i.e. it doesn't need refrigeration, right? So, why? Thanks.
I do not use the gelled alcohol to boil water. I use it to cook with (frying, and sauteing) as the heat produced is lower than straight denatured alcohol.
I still have my old Sterno stove that I got in the 1980s during my first tour in the Marine Corps at 29 Palms Ca along with a couple of canteen cups that I used for everything
Good explanation of the process. I’ve made my own gel fuel using acetone and styrofoam and it’s fine for outdoors but this would be better for rainy days in the tent. It seems that using a second altoids tin as a spacer would get the heat closer to the pot Have you tried using a tin with the lid still attached and closing the lid to extinguish the flame for conserving fuel once the flame is no longer needed? Great video.
I had a hard time seeing you at first because you perfectly melded in with the backround camo Great info, gonna try making tomorrow for uocoming winter camp trip
Small vacuum tab on the mason jar would speed up and improve the alcohol take up process. When opening for the first time the take up is obvious . Thanks mista . This has been fun .
Why does it need to be gel'd? I've made alcohol stoves out of beer cans that use just alcohol, and they seem to work just fine. What is the advantage of gel?
The intensity of the flame is much lower that pure alcohol. I made this gel and my perlite stove specifically for my Esbit rectangular cook set. most alcohol burners will not fit with enough room to burn properly. I use my perlite alcohol stove to boil water and my gelled alcohol fuel to cook with. PERFECT amount of heat to fry, sauté', without scorching or burning. It works better than my Trangia burner with simmer ring. That's why I use gelled alcohol and I made it because I wanted the experience of doing it and it's cheaper than Sterno, the closest manufactured equivalent.
@@boonedockery7220 Still, no clear reason to use gelled alcohol. Only that you use it. So what is the advantage of using gelled alcohol? I don't see one.
@@Greg_M1I use both and the reason for me is that some alcohol stoves and fireplaces are only made for gel alcohol and not liquid. Although I use both I find gel much easier to work myself.
The only advantage I see is safety, impossible to spill. You could also stuff a Sterno can with cotton swabs or fiberglass insulation and just use liquid alcohol instead of making a gel.
I'm wondering if this would work with high test ethanol, so you could safely roast marshmallows over the flame. Might not get as hot, I have no clue, but would be plenty satisfying the kids when the location won't allow an open fire.
Very cool.....excellent idea for backpack or hunting backpack emergency fire starter. Can you order smaller containers of the Calcium Acetate? Do you have a link for the Calcium?
The calcium is also good for putting on your garden at the end ofna grow season to help replenish the soil. 😁 Never thought of using some as a wick though
We raise laying hens and we always throw our egg shells in the compost. At the end of Fall we put a layer of the compost over our soil. After tilling in the Spring you can barely see a recognizable egg shell. So I guess I've been adding calcium acetate to my garden for years and never ever thought about it. I guess Bob Ross would call that a "Happy Accident"! I'm no chemist, had it not been for watching Hiram Cook's video, I never would have known about it. Hiram hasn't posted a video in 7 years. He is a GURU with DIY camp stoves and fuels. If you haven't checked his channel out, It's well worth your time. www.youtube.com/@MrHiramCook/featured
Wondering if a pure powdered soap like (I think) Lux pure soap flakes would also work to make a variation of this gelled alcohol. I think the soap flakes would burn and likely absorb alcohol. Not sure how it would release the energy.
I have a couple questions for all you experienced folks. Can I increase the volume of material, but keep the ratios the same, to make a larger batch at once, or is there a reason to mix up smaller batches? Can the left over calcium acetate be reused after the burn, to recycle into a new batch? I’m just learning about all this and have already purchased all three ingredients. I haven’t mixed anything yet. Thanks in advance!!
Yes, you can make large batches providing you keep the proportions. I have never tried to reuse the calcium acetate. I would recommend making a small batch first, then go for the 55 Gallon batch!
I watched your perlite video and was intrigued with the possibilities. Have you or anyone else tried combining the perlite method WITH the gelled fuel??? What would happen? Is there anything to be gained there? I was hoping that using both together might give you a more consistent, longer lasting flame?
Love it and I scanned the comments to see if you referred to how many TBSP it took to make the 2/3 quart Gel. What I am thinking if making a Quart or maybe near a Gallon. I have friends who bushcraft and making little jars of it sounds like a great gift idea. But I don't want to make tiny amounts at a time, rather make a large amount an just scoop and seal. I think you get the idea. Doing the math I think I am right for 1 full QT (or near that), I am thinking 2 cups Distilled Water (4 to a qt), 1 Cup Calcium Acetate and 4 Tbsp of Denatured Alcohol?
you should see if it's possible to recycle the calcium that is left over from the gel after you burn it. that would be great and i think it might just work
I'm going to make some of this stuff, but I will use Chalk to make my gel fuel. I will use a old Stainless Steel 1/4 measuring cup to hold the fuel. Nice, but how do you transport it in small portions, to burn in your stove? Can you freeze it into say cubes? And then wrap in foil or plastic?
Adding gelatin (or probably agar, too) to the water and acetate helps it set up better. Adding a little lamp oil, Zippo lighter fluid to the alcohol helps it burn hotter. I have no idea about ratios, but we used it to refill our Sterno containers in Boy Scouts, back in the '70's, when Sterno was common for backpacking. (Those Sterno cans fit inside old soda cans perfectly, so you could make stove stands easily.) I remember adding too much fuel could ruin an entire batch and it wouldn't set up.
Brother John, we see a new side to you. Didn't know that you were a chemist. I find this new to me fuel to be intriguing and much better than any solid fuel I have ever used. I agree with you that solid fuel is smelly and makes a mess of the cook pot, but it is convenient to carry. And speaking of carrying, how do you transport this conveniently? Inquiring minds want to know! Great teaching video my friend!
Thank You Brother David! I have a large bin filled with all kinds of recycled containers. I used one shaped like a giant test tube with a screw on cap. it was perfect to cook two meals with.
What I did with the batch I made I either added cotton balls, or the kitty litter that’s looks like goose turds. 3D Printed 2x2x1” cubs with TPU seal top. Place either cotton ball or kitty litter on containers. Fuel becomes more like the solid tablets.
I wonder how it would do if you filled a pint or quart sized paint can with it and lit it, if that would be a better solution to the toilet paper alcohol stove or if it would be too ashy after the top layer burns off
I'm sure there's a reason and an explanation that I have not found - why you don't make a larger batch. Have you used any type of blending tool such as an egg Blender?
I could definitely do that. The batches I've made really last a long time, and storage space is at a premium in my garage. "IF" I'm able to retire soon and do the channel full time, I'd be going though a lot more of the gell which will necessitate larger batches
I am potentially wanting to make cans of this stuff to use with the "VESTA Self-Powered Camping Indoor/Outdoor Heater & Stove" as an emergency heat source. How do the canned fuel people make this stuff last for six hours. Is it just the quantity of the gel in the can?
Great video, I'll definitely make some, but have a couple chemistry/safety notes. The Yellow in the flame is mostly burning Acetone (think fingernail polish remover). The acetone comes from the calcium acetate where some of it has dried out enough to get over 300f and it decomposes. This isn't really a problem but it can have a smell and you don't want to breathe the fumes. While the burning ethanol creates almost pure Water and CO2 when it burns with enough air, there is no telling what the "denaturing" agent makes in addition to the odd bits made by the burning acetone. The short answer, TLDR as they say, is always have ventilation when you burn anything in an enclosed space. Back in the Great Texas Freeze Out we ripped through all our camping fuel and always keep my eyes open for alternate emergency heating and cooking methods and supplies. This one 100% goes in our toolkit. Thanks for sharing!
I found your video of much interest. Some years ago I came across a video illustrating the making of solid fuel cells using kieselguhr and methanol but as this was on no interest to me at the time I did not a note of the instructions. I am now interested in the solid fuel cell due to the cost of cooking gas having insanely gone up in the third world country where I live. Would you know of this method and the proportions, the type of container etc etc. I hope you will be able to help me out.
You and I think alike! I tried that, yet it did not work on it's own, it only clumped up. I then tried scooping out the clumps and adding more solution, but it just made it more watery. It still burns great, just doesn't have the consistency it did before.
@@pinklickpony7162 Definitely not. Calcium carbonate are what the eggshells are formed of. Calcium acetate can be made by dissolving eggshells in vinegar, otherwise known as acetic acid. The two combine to make a different compound.
Anything less than 91% alcohol does not burn clean. My bioethanol has no smell. Absolutely love the video but I'm thinking that having to buy 91% alcohol to make this would wind up being very expensive. I have ethanol fireplaces big ones and small ones for cooking also. But the caned gel alcohol that I buy for the fireplace is pretty expensive. About $100 for 24 cans, but burns for 3 hrs. Was looking at this as a less expensive alternative. Would you be so kind as to give me your opinion on this?
If you want to burn alcohol in your tent buy the indoor stove type. No poisonous fumes. Any other type of denatured alcohol is dangerous to breathe or drink. Of course Everclear would also work
It appears that it is most effective and very simple thank you very much for the chemistry lesson. In the words of a cook I used to watch, and for the life of me his name escapes me, don't cut yourself don't burn yourself I see you and it is not Justin Trudeau, at least I think that was the name of that Cajun Cook. I think you put a link to those green containers that you have there in the last video you did so I'm going to check otherwise I wish you would send me a link to them I love those things. Thanks for the video brother. PS you must not have had any bloopers this time
The Cajun Cook was Justin Wilson. I LOVED His cooking program! It was on our local PBS channel for years. Here's the link for the fuel bottles. amzn.to/3q3jzxq I actually didn't have time to edit a blooper segment, I'll try to get one for the next one for you! Have a great weekend Brother!

There is great changes in store for me, I may tell you about it here before too long. I will have a good time this weekend and I certainly hope you do too.
I have seen people extracting alcohol from hand sanitiser using salt Would this work with your set up rather that denatured alcohol and would it be any cheaper ?
This video is great. I did not know you could make your own fuel. Can you make the step by step video with the eggs shells. I have tons of egg shells. II use them on my garden. Now i know i can make fuel.
I am curious if you could add alcohol to the used portion left in the tin to make another batch. In other words can the used mixture be reconstituted, or does the calcium get damaged in the fire.
Never eat in your tent. Bear safety rule number 1. Also, never have anything burning in your tent.
I will pin your comment. Thanks for the advice!

In my backcountry experience, typically at 10,000 ft ASL, I get 12 oz of water to boil w/ just straight denatured alcohol in 10 minutes... which is how long the alcohol lasts, coincidentally. So why gel? Does it carry well in the backcountry, i.e. it doesn't need refrigeration, right? So, why? Thanks.
I do not use the gelled alcohol to boil water. I use it to cook with (frying, and sauteing) as the heat produced is lower than straight denatured alcohol.
Although I use both gel and liquid alcohol I prefer gel and I find it much easier to work with. Also some bioethanol fireplaces only take gel.
I still have my old Sterno stove that I got in the 1980s during my first tour in the Marine Corps at 29 Palms Ca along with a couple of canteen cups that I used for everything
I had one of those too! I have no idea what happened to it?????
Good explanation of the process. I’ve made my own gel fuel using acetone and styrofoam and it’s fine for outdoors but this would be better for rainy days in the tent. It seems that using a second altoids tin as a spacer would get the heat closer to the pot Have you tried using a tin with the lid still attached and closing the lid to extinguish the flame for conserving fuel once the flame is no longer needed? Great video.
I made this specifically for my rectangular Esbit cook set. The space between the pot and flame is near perfect.
Excellent. Now I can refill those surplus swiss M71 stoves. Thanks for sharing !
Perfect!!!!
I had a hard time seeing you at first because you perfectly melded in with the backround camo
Great info, gonna try making tomorrow for uocoming winter camp trip
😅😆😄👍
If egg shells are used, same 1/4 c.? Plus anything else (vinegar)?
I will have to do a little more research and post a video of the process. Then I will be able to answer your question.
Small vacuum tab on the mason jar would speed up and improve the alcohol take up process. When opening for the first time the take up is obvious . Thanks mista . This has been fun .
Very cool thanks for the vid definitely gonna try this out cuz I love my sterno set up
Have fun!
Why does it need to be gel'd? I've made alcohol stoves out of beer cans that use just alcohol, and they seem to work just fine. What is the advantage of gel?
The intensity of the flame is much lower that pure alcohol. I made this gel and my perlite stove specifically for my Esbit rectangular cook set. most alcohol burners will not fit with enough room to burn properly. I use my perlite alcohol stove to boil water and my gelled alcohol fuel to cook with. PERFECT amount of heat to fry, sauté', without scorching or burning. It works better than my Trangia burner with simmer ring. That's why I use gelled alcohol and I made it because I wanted the experience of doing it and it's cheaper than Sterno, the closest manufactured equivalent.
@@boonedockery7220 Still, no clear reason to use gelled alcohol. Only that you use it. So what is the advantage of using gelled alcohol? I don't see one.
Lower more controlled heat, and the alcohol won't evaporate away, it can be stored long term.@@Greg_M1
@@Greg_M1I use both and the reason for me is that some alcohol stoves and fireplaces are only made for gel alcohol and not liquid. Although I use both I find gel much easier to work myself.
The only advantage I see is safety, impossible to spill. You could also stuff a Sterno can with cotton swabs or fiberglass insulation and just use liquid alcohol instead of making a gel.
I'm wondering if this would work with high test ethanol, so you could safely roast marshmallows over the flame. Might not get as hot, I have no clue, but would be plenty satisfying the kids when the location won't allow an open fire.
I honestly don't know. It would be worth testing!
Now, could you use powdered gelatin to help jelly your fuel?
Corn starch would be nice to try also
Very cool.....excellent idea for backpack or hunting backpack emergency fire starter. Can you order smaller containers of the Calcium Acetate? Do you have a link for the Calcium?
I am confident you can purchase Calcium Acetate in smaller containers. I posted a link to the size I ordered in the video description.
I LOVE YOUR CONTENT
I subbed.
Bill, from Tn. 🇺🇸
Thank you very much! Welcome to the family Bill! I LOVE Tennessee!
Neat, about how many eggshells will it take to make a cut of this fuel ? and will eggshells work as well as Calcium Acetate?
Haven't got a clue. I've never made it myself.
The calcium is also good for putting on your garden at the end ofna grow season to help replenish the soil. 😁
Never thought of using some as a wick though
We raise laying hens and we always throw our egg shells in the compost. At the end of Fall we put a layer of the compost over our soil. After tilling in the Spring you can barely see a recognizable egg shell. So I guess I've been adding calcium acetate to my garden for years and never ever thought about it. I guess Bob Ross would call that a "Happy Accident"!
I'm no chemist, had it not been for watching Hiram Cook's video, I never would have known about it. Hiram hasn't posted a video in 7 years. He is a GURU with DIY camp stoves and fuels. If you haven't checked his channel out, It's well worth your time. www.youtube.com/@MrHiramCook/featured
Wondering if a pure powdered soap like (I think) Lux pure soap flakes would also work to make a variation of this gelled alcohol. I think the soap flakes would burn and likely absorb alcohol. Not sure how it would release the energy.
Haven't gotta clue....
Thanks for this gem!
My pleasure!
I have a couple questions for all you experienced folks.
Can I increase the volume of material, but keep the ratios the same, to make a larger batch at once, or is there a reason to mix up smaller batches?
Can the left over calcium acetate be reused after the burn, to recycle into a new batch?
I’m just learning about all this and have already purchased all three ingredients. I haven’t mixed anything yet. Thanks in advance!!
Yes, you can make large batches providing you keep the proportions.
I have never tried to reuse the calcium acetate.
I would recommend making a small batch first, then go for the 55 Gallon batch!
@@boonedockery7220 lmao! Thank you so much for your help! I think I’ll do just that! Jk. I’ll keep you posted on the results!
What if you mix the perlite in with this mixed using them together. I think you have a lot more residual heat left over with the add perlite
I have never tried this???????
Be waiting for your next video to see how it turns out
I watched your perlite video and was intrigued with the possibilities. Have you or anyone else tried combining the perlite method WITH the gelled fuel??? What would happen? Is there anything to be gained there? I was hoping that using both together might give you a more consistent, longer lasting flame?
The perlite needs liquid alcohol to create the controlled burn.
Love it and I scanned the comments to see if you referred to how many TBSP it took to make the 2/3 quart Gel. What I am thinking if making a Quart or maybe near a Gallon. I have friends who bushcraft and making little jars of it sounds like a great gift idea. But I don't want to make tiny amounts at a time, rather make a large amount an just scoop and seal. I think you get the idea. Doing the math I think I am right for 1 full QT (or near that), I am thinking 2 cups Distilled Water (4 to a qt), 1 Cup Calcium Acetate and 4 Tbsp of Denatured Alcohol?
Just keep the ratios the same and you should be good to make as large a batch as you wish.
you should see if it's possible to recycle the calcium that is left over from the gel after you burn it. that would be great and i think it might just work
I will.
Add it to garden soil. Egg shells have been used like that
Thanks that's a good thing to know. I imagine a circular burner with draft holes would burn better than in a rectangular unvented tin
So, after it's all burned up to powder and what's left is calcium acetate...can that calcium acetate be reused to make more fire gel?
yes
I'm going to make some of this stuff, but I will use Chalk to make my gel fuel. I will use a old Stainless Steel 1/4 measuring cup to hold the fuel. Nice, but how do you transport it in small portions, to burn in your stove? Can you freeze it into say cubes? And then wrap in foil or plastic?
You can crumble it up and reconstitute it for reuse.
Adding gelatin (or probably agar, too) to the water and acetate helps it set up better. Adding a little lamp oil, Zippo lighter fluid to the alcohol helps it burn hotter. I have no idea about ratios, but we used it to refill our Sterno containers in Boy Scouts, back in the '70's, when Sterno was common for backpacking. (Those Sterno cans fit inside old soda cans perfectly, so you could make stove stands easily.) I remember adding too much fuel could ruin an entire batch and it wouldn't set up.
Great info! Thanks for sharing it!
Him: "It's like being in the gas chamber"
My brain: HE'S A VETERAN! 😂
We know things...... :)
Brother John, we see a new side to you. Didn't know that you were a chemist. I find this new to me fuel to be intriguing and much better than any solid fuel I have ever used. I agree with you that solid fuel is smelly and makes a mess of the cook pot, but it is convenient to carry. And speaking of carrying, how do you transport this conveniently? Inquiring minds want to know! Great teaching video my friend!
Thank You Brother David! I have a large bin filled with all kinds of recycled containers. I used one shaped like a giant test tube with a screw on cap. it was perfect to cook two meals with.
9:51 look at his pocket. a spider crawls out and around 😂
That looks to me like a fly landed on the front of the pants and walked across the top of the pocket and then down the front of the pocket.
Mix both together ,love it thanks
Thank You!
Thank you so much for this video.
You are so welcome!
Loved this! Thank you so much!
What I did with the batch I made I either added cotton balls, or the kitty litter that’s looks like goose turds. 3D Printed 2x2x1” cubs with TPU seal top. Place either cotton ball or kitty litter on containers. Fuel becomes more like the solid tablets.
VERY COOL! Thanks for sharing that!
Do you still mix calcium?
Great video.......!!!.....do you know how many ounces a table spoon of this weighs......? Thanks a million....!!!
Can we use rubbing alcohol instead of denatured alcohol What is the difference on the burn???
I wonder how it would do if you filled a pint or quart sized paint can with it and lit it, if that would be a better solution to the toilet paper alcohol stove or if it would be too ashy after the top layer burns off
I would like to seeing you do it with the eggshells maybe next video mate, thanks Graham
could you reuse the calcium acetate after burn [since the alcohol is burned off] to make a new batch?
I don't know. I am saving used calcium acetate until I have enough to make a batch to try.
Sorry, I'm a noob. Does it have to be denatured alcohol, or will a high-proof isopropyl work as well? Thanks in advance.
Denatured alcohol burns cleaner than isopropyl, but it will work at 90-99%
I would not get anything less than 91%. Anything less does not burn
I'm sure there's a reason and an explanation that I have not found - why you don't make a larger batch. Have you used any type of blending tool such as an egg
Blender?
I could definitely do that. The batches I've made really last a long time, and storage space is at a premium in my garage. "IF" I'm able to retire soon and do the channel full time, I'd be going though a lot more of the gell which will necessitate larger batches
I am potentially wanting to make cans of this stuff to use with the "VESTA Self-Powered Camping Indoor/Outdoor Heater & Stove" as an emergency heat source. How do the canned fuel people make this stuff last for six hours. Is it just the quantity of the gel in the can?
Great video, I'll definitely make some, but have a couple chemistry/safety notes.
The Yellow in the flame is mostly burning Acetone (think fingernail polish remover). The acetone comes from the calcium acetate where some of it has dried out enough to get over 300f and it decomposes. This isn't really a problem but it can have a smell and you don't want to breathe the fumes. While the burning ethanol creates almost pure Water and CO2 when it burns with enough air, there is no telling what the "denaturing" agent makes in addition to the odd bits made by the burning acetone. The short answer, TLDR as they say, is always have ventilation when you burn anything in an enclosed space. Back in the Great Texas Freeze Out we ripped through all our camping fuel and always keep my eyes open for alternate emergency heating and cooking methods and supplies. This one 100% goes in our toolkit. Thanks for sharing!
Excellent vid. Thanks! Question: how do you transport it? If I wanted to take it backpacking, for example.
I wonder if an old blender would work, or an old stand mixer to combine everything?
It begins to jell instantly. If anything a small whisk would work well.
I found your video of much interest. Some years ago I came across a video illustrating the making of solid fuel cells using kieselguhr and methanol but as this was on no interest to me at the time I did not a note of the instructions. I am now interested in the solid fuel cell due to the cost of cooking gas having insanely gone up in the third world country where I live. Would you know of this method and the proportions, the type of container etc etc. I hope you will be able to help me out.
I'm sorry, I've never attempted to make my own solid fuel. However, I will look and if I find something that works, I'll post a DYI video about it.
Great video and useful information. Is it possible to add more calcium acetate to you old batch to make it more solid?
You and I think alike! I tried that, yet it did not work on it's own, it only clumped up. I then tried scooping out the clumps and adding more solution, but it just made it more watery. It still burns great, just doesn't have the consistency it did before.
But does the homemade gelled alcohol/sterno stink? I'd like to use it to heat a sand battery I'm going to make in an antique kerosene heater.
What would the recipe be with 91% isopropyl (rubbing) alcohol? Thanks!
Denatured alcohol burns cleaner than isopropyl.
How to make Calcium Acetate using eggshells? Do you just grind the shells until they become powder?
I can't find a store that sells denatured alcohols. I read that METHYL HYDRATE is similar, is that true?
Hardware stores in the paint area is where I buy mine.
Once this is burned it converts to calcium carbonate (eggshell again) and a small amount of acetone which further fuels the fire
Cool! Thank you!
Does it mean , you can recycle the use of it again? like adding Vinegar or Acetic acid??? 😮
So is calcium carbonate the same as calcium acetate?
@@pinklickpony7162 Definitely not. Calcium carbonate are what the eggshells are formed of. Calcium acetate can be made by dissolving eggshells in vinegar, otherwise known as acetic acid. The two combine to make a different compound.
if after burning it it leaves only pure calcium assitate behind, can't you reuse it to make more?
Is it safe to use indoors for cooking?
Question"- Once solution burns, you said what's left is raw Cal. Ace., have you tried reusing this to make another solution to add alcohol to??
I haven't yet.
Is there any type of residue left on the coookware from the gel ?
No.
Anything less than 91% alcohol does not burn clean. My bioethanol has no smell. Absolutely love the video but I'm thinking that having to buy 91% alcohol to make this would wind up being very expensive. I have ethanol fireplaces big ones and small ones for cooking also. But the caned gel alcohol that I buy for the fireplace is pretty expensive. About $100 for 24 cans, but burns for 3 hrs. Was looking at this as a less expensive alternative. Would you be so kind as to give me your opinion on this?
What kind of alcohol? Isopropyl, denatured, Eveclear?
I used denatured.
Instead of vinegar, can acetic acid work to make the calcium acetate solution?
I honestly don't know.
If you want to burn alcohol in your tent buy the indoor stove type. No poisonous fumes. Any other type of denatured alcohol is dangerous to breathe or drink. Of course Everclear would also work
It appears that it is most effective and very simple thank you very much for the chemistry lesson. In the words of a cook I used to watch, and for the life of me his name escapes me, don't cut yourself don't burn yourself I see you and it is not Justin Trudeau, at least I think that was the name of that Cajun Cook. I think you put a link to those green containers that you have there in the last video you did so I'm going to check otherwise I wish you would send me a link to them I love those things. Thanks for the video brother. PS you must not have had any bloopers this time
The Cajun Cook was Justin Wilson. I LOVED His cooking program! It was on our local PBS channel for years. Here's the link for the fuel bottles. amzn.to/3q3jzxq
I actually didn't have time to edit a blooper segment, I'll try to get one for the next one for you!
Have a great weekend Brother!
@@boonedockery7220 that's right it was on PBS, thanks for jogging my memory. I went back to your previous video and you did put a link and I did go and get me a couple of those I love those things and thanks for the link you put in this comment. There is great changes in store for me, I may tell you about it here before too long. I will have a good time this weekend and I certainly hope you do too.
@@terryqueen3233 Prayers for you and your "great changes" Brother! God Bless! John
How many dozen eggs do you need to make 1/4 cup of Calcium Acetate?
I do not know.
Is it good to the lungs
And can you use a tuna can for burning the tbsp?
I was just wondering if you can't find calcium acitate will egg shells work?
I have seen people extracting alcohol from hand sanitiser using salt
Would this work with your set up rather that denatured alcohol and would it be any cheaper ?
This video is great. I did not know you could make your own fuel. Can you make the step by step video with the eggs shells. I have tons of egg shells. II use them on my garden. Now i know i can make fuel.
It's on my massive list of things to film!
Was wanting to know if I could use calcium citrate instead of calcium acetate?
I honestly don't know. I have never tried it.
Could this be used in the small alcohol stoves? Like the Trangia tiny alcohol stove?
Cool project! Thanks for sharing 😊
Awesome, I'm glad you liked it! Thanks for watching!
I wonder if you added a bit of calcum acetate to the jar and shake up to see if it would re-solidify more
Have you tried reusing the burnt calcium acetate? If you do can you let us know if it works? Awesome video. Thanks for the info.
Quick question for creator mine turned watery after 24 hours still burns fine but curious what I did wrong
Hmmmmm..... I've never had that happen. I would suspect their may have been an issue with the calcium acetate or perhaps the ratios????
@@boonedockery7220 I made a new batch we will see
I am curious if you could add alcohol to the used portion left in the tin to make another batch. In other words can the used mixture be reconstituted, or does the calcium get damaged in the fire.
This is an excellent idea for further experimentation. I have never tried recycling the calcium.
What kind of alcohol should be used? A 100% or is 91% ok too?
