Very similar thing is made by bushcraft and survival people. Charr cloth is one of the best materials to catch a spark from a flint and steel. Usually it's made in a small tin can with a little hole for gasses to escape. Material (denim, wood or other stuff) is placed in the can, then put into a fire. Process ends when there is no smoke coming out of the hole.

We did this with gun cleaning patches in the field with a muzzle loader club I used to belong to. We would live a weekend with only period equipment and flint and steel were the only firestarters we could use.

The main rule of thumb when making char-cloth is that the material has to be 100% cotton, or you just end-up with a burnt mess.

There are few among you who should teach…you are one of the few. Cheers.

Thanks for sharing this, and so many other fascinating things! Much appreciated! 😊

I made my carbon cloth experiment from old socks that had holes in them, didn't bother to wash them before and fresh out of the fire they had slight smell of sulphur or something pungent odor that diminished as time went, although I thought that the socks would've been more malleable they were quite brittle like typical wood char, breking easily so it was a little bit of dissapointment. But cotton wool/absorbent cotton, that I used as a filter for outside air inlet, that is better to carbonise, still got some and I did all my carbonisations on a fire pit outside (of course). I have a little tea jar that has 2 lids in it, the inner lid I put several tiny holes and the outer lid only one bigger hole, works well enough for couple of times, since the metal has started to scale off already after couple of uses so its not forever lasting, but well recycled at that.

I have been trying to figure out how to make some charcoal in my fire pit. Could an old pressure cooker with a twist on lid work if there is a bigger hole added to the lid?

Great video. Thank you. So good to have simple straightforward videos on how to make elements that are so useful, but maybe tricky to find out how to DIY.

I absolutely love you chemistry lessons. Thank You 🙏

Excellent video again & as usual I have learnt from you. Thank you.

doing this with a microwave kiln, obviously not keeping the microwave oven powered for too long for these kilns heat rapidly, will surely give a similar result although the swings in temperature may induce stress in the material.

Working on a supersuit for the new year... Nice

The graphitized denim is really awesome! It´s flexible - but what about tensile strenght?

Great video. I have a suggestion for people who might want to dial in the time-temperature values. I will give this a try myself. This is entirely speculation - but it seems to line up with 30 year old college knowledge. With a square ohm tester, you can have quick data points. Pick two times and two temperatures to get 4 data points. With four data points of conductivity across time and temperature, you could predict good time-temperature combinations pretty accurately. If it is predictable... I assume that all these data points should fall on a line - it is likely to be some constant times duration in seconds vs [log absolute temp]. This feels like a reaction that would follow a "natural log of temp times duration" model...

Hi Robert, have you thought (or you may already use) an orthogonal array for optimisation? It is a wonderful tool that allows you to change 2 factors but still being as accurate as a full factorial. Have a wonderful day 😊

Robert, could you please demonstrate how to make activated charcoal on a small scale using steam? Thanks

If you replace the air in the can with *carbon* dioxide, would that enhance the final product? I’m thinking the small amount of air in the can will cause some ash high is no good in the final product.

Robert I can't explain how I've been searching for this since you started talking about it as a wick for pyro and electrical experiments... And here we are. I was about to try copper pipe with dryer lint in it. Pyrolize it and cut the ends square with pipe cutter and then cut the felt inside with a knife and a finished wick (for oil lamp experiments)? I'll report back.

@townbell2248 i'll do my best to remember! Tasks go very tangent around here.

I've successfully made char cloth in little Altoid tins. You can toss it into a campfire for 10-15 minutes and be done with it. 5-6 years ago. I tried to char feathers in a tin, attempting to make graphene but the tin exploded and the feathers stank horribly. Now I want to char human waste to make biochar that could be safely added to soil. I want to avoid making shite bomb, though, so I've decided to make an anaerobic waste incinerator from a metal ammo can. I will replace the plastic gasket with some fiberglass rope (the kind used for stove doors) and drill a vent for the super-heated gases to escape. Then I've got to get a burn barrel and maybe a long handled propane torch. I'm concerned that the paint from the ammo can may contaminate my biochar. Any feedback on this?

@townbell2248 I'm sorry, I wasn't very clear about that. The Altoids tin worked great. No problems. I put the feathers in a significantly larger tin. Maybe 8" tall and 5" in diameter. If memory serves, I did put a few small vent holes in the lid. Apparently not enough to release the pressure of an increased volume of super heated air in the larger tin. A smaller space & more carbon-based stuff will be, ahem, safe and effective. Fill it up, pack it in, as long as the lid closes securely. You can't imagine how nasty burnt feathers smell...

very good material. i wonder if this could be used to make a lightweight material using resin and layering these carbon sheets!

How about ever soaking the cloth or material to be baked, is KOH only used with solid Wood,and hemp fibers? and what is the results

Carbon pine cones look really cool.

So basicly a piece of denim in a stainless pot covered with grafite powder in the kiln on 700celcius for 4 hours.

Thx , I'm curious about the origin of this process . I can't see it going back further than to mid 1800s . Edison making his carbon filaments from finally bamboo slivers seems to indicate there was a prior state of art but not widely known since Nikola Tesla and others scoffed at his pursuit of carbon fibre filaments . It appears to be analogous to to the fashioning of the gas mantle for gas lighting which produced excellent light at the flick of a valve , but where the gas mantle is based on silicon ( that is silicon oxide which cannot react further with oxygen at high temperature ) the carbon filament is based on carbon (which cannot react futher with oxygen at high temperatures within a light globe cos it's in a vacuum and there's nothing for it to react with ) ......we have the gas mantle still today fot camping , we buy the propane/butane gas cylinders and fresh mantles and the equip ment that holds the mantle and produces the flame to heat the commissioned mantle and produce a bright glow thanks to lanthanide/rare earth àdditives . . But that fresh mantle prior to being commissioned by a burn up ( then the matrix of the carbon based fabric becomes the framework of the newly commussioned mantle ) is some kind of fabric like cotton impregnated with silicates and chosen lanthanide nitrates or along those lines . It's equipment that may not be available much longer due to adoption of led lighting in camping situations. And I've lost the train of thought, but Faraday long ago gave a three hour lecture on the candle flame and light output. A lecture for the gas mantle could go several days .

I have a Technical Question for Graphene Blending Method: If the Coating Substance for preventing Graphene to collapse into Graphite when Compressed is A Protein what would happen when it comes in touch with high level of Heat? Turning Graphitic and collapsing the whole Graphene Sheets together? What could be used to prevent this other than click chemistry to some High Heat Resistance Molecular Binder? The One on One Kitchen Laboratory Method for Grafting Graphene Molecules to one another without being Kaner and having more Openly Sentimental Letters from Scientific Journals than Lovers... I am aware that Molten Salt is both a perfect way to Exfoliating Graphene and Storing it under Its Otherwise Decadent Form..but I don't own a Furnace to reaching Salt's Melting Point.. [Yes I know It is Low...I don't have a use outside the Kitchen I guess... But I can Cook tho... fairly...but I don't think Maillard reaction will gonna help me with this..unless it can Bond Micronised metals to Graphene Molecules without later turning into Carbon Powder once Heated...] Suggestion? I think also annealing by Mechanical Pressure Metal Coated Graphene Molecules might be a potential Handyman Solution... ...but again I think we are all missing the Elephant in the Room with Graphene. [I was kinda Joking, but what about mixing With the Maillard Reaction Sugars-Proteins-Water Soluble Minerals as Calcite from Ashes and burning it in the hoven in order to create Carbon Bonds between Graphene's Layers and Calcite...?]

I would love to scale this up enough to make a permeable fabric to cover greenhouses, to filter chemtrails out of the rain.

I think I will try Fiberglass.

Could you use induction to heat carbon cloth? Like if you put carbon cloth onto an induction cook top would it conduct enough to get hot like a stainless steel pot?

Could the Prussian Blue in denim be helping the graphite process as it contains iron?

It seems this method is easier for larger structures like current collectors compared to hydrothermal carbonisation. I can do only small quantities in the autoclave. Are there other (qualitative) differences?

Awesome.. Thanks for demonstrating this process. What do you do with the carbon + steel mesh after you are done with the process?
