don't mind me, just leaving a comment for the algorithm, using words such as awesome, marvelous, exciting and extremly interesting

Yo KZfaq, this guy is no joke. His content deserves to be on the A-List. The amount of research he does deserves some kind of an Award. The knowledge he is conveying needs to be seen by all.

this is exactly the type of person we need to teach our nations youth, someone do and teach.

Hey guys, I took some notes on the materials, techniques, and experiments he's done. I may be missing a few things, comment with more notes if there's anything else! *Materials:* Wood Flour - 2:36 Fumed Silica (Cabosil) - 7:16 Pre-made thickener regarding previous materials - 13:41 Hollow Glass microbeads - 14:16 Microfibers (glass, polyproplyene) - 20:05 Chopped fibers (glass, carbon, basalt) - 21:20 Carbon - 22:22 Basalt - 24:20 Powders (Graphite, aluminum, dendridic copper) - 25:22 dendridic copper - 26:13 nanoscale aluminum nitride - 27:25 Boron Nitride - 27:55 Aluminum Oxide abrasive grains - 29:45 Silicon Carbide - 30:07 Titanium-coated diamond - 30:49 *Techniques:* Thickening epoxy - 7:18 Dispensing: Using Caulking tubes - 10:06 Using a sandwich bag - 11:25 Spreading with sticks - 12:24 Fix wood imperfections and minor damage - 16:16, 19:07 Improving epoxy absorption - 18:16 Throwing away epoxy without melting garbage - 19:50 *Experiments:* Potential armor composites - 28:31 Thermal epoxy - 26:10

well... you did it again. you made me sit through a 30 minute video completely fascinated the whole time. incredible.

I am extremely interested in learning about those concrete speakers. Hopefully we will get to see a video about them soon. Hands down, this is my favorite channel on KZfaq.

This is the only channel that I can say that for every video I've learned something profoundly new about a subject I felt I was already familiar with. I love what you guys do. Thank you

"titanium coated diamonds" Hearing that made me very happy.

Only 3 minutes in, I knew nothing about epoxy additives but I do know what peanut butter is. Beautifully presented, clearly explained from an expert to someone with no experience and a pleasure to watch. When technical advice is presented like an engaging, practical lecture you remember why KZfaq was created. What a treat.

I have to be honest, this is one of the most remarkable KZfaq epoxy engineering discussions I've seen. My father is a metallurgist who invented AerMet 100, one of the toughest, strongest materials on the planet and I have always had tremendous respect for people who take material science to the next level. Your ballistic epoxy concept reminded me of the year or so that I spent in civil engineering, using a material called 2A Modify. While it was nothing but different grades of gravel, it was so naturally dense when compacted because of the size mix (just like your discussion of densification) that it became as hard as a brick (probably harder) - you could break it apart, but you had to use a large hammer and put your arm into it. I'd love to hear what you do to develop that composite. Sounds fascinating. On a more personal level, I'd love to hear what options there are for casting epoxy with an embedded carbon fiber matrix. It sounds like there's some work to be done to cope with that unusual viscosity and clumping, but your comments gave me hope that there's a smart method available...perhaps adding Boron Nitride? Again, great video!

I would much rather you be safe when using that silica dust than breathe it in. Nasty stuff. You should mask up and just dub in a voiceover afterwards.

wow that info on those thermal interface epoxies is so cool, you could probably write a paper on your findings.

First part: This mixture can be used for a good corner bond with wood. Last part: We can use this with skme kevlar sheets to stop bullets. Holy damn we went to 100% in just 25 minutes!

I absolutely love how approachable the channel is. It's like halfway between sparknotes and a college level lecture.

feel this is more useful than the engineering class I took in college.

This was so good, I came to watch just few minutes but it was impossible to not finish. Armor made of some glue and diamonds? Minecraft is true prophet :^D

Few people can explain things so clearly as this man. Incredible job!!

These kinds of deep dives are always appreciated. Great content.

I can't get enough of these videos! There are educational videos, then there are expert videos, then there are cutting edge research videos, then you have Tech Ingredients. What do you even call this field of applied science, chemistry? Material science? Industrial engineering? Whatever it is I love it. It's well explained and gives the hobbiest enough to start trying it in projects. Great stuff my dude.

This is by far and away, the single most intriguing channel on KZfaq. The work you are sharing with us is beyond fascinating.

I'm a simple man, I see tech ingredients I have to check it out.

really appreciate how through this channel gets in their projects

I am excited for the ballistic test!

When you understand the reason for the rules, you know how to break them safely.

I AM SO HAPPY ABOUT THE COMPOSITE VIDEOS!

This was AWESOME! Can't wait to see the ballistic results!!! Thank you so much for sharing your amazing insights!

Incredibly well explained. KZfaq is full of epoxy videos to stumble upon, yet somehow I think you've managed to make the most interesting one I've seen yet; not just dipping items in epoxy, but making true composites with useful properties.

This was one of the most interesting and informative videos I have ever watched. I love the way you think about solutions for applications based on the material properties and the best part is that your content is not just theoretical, but based on practical experimentation and observation to verify the results. Thank you for such an excellent video and awesome series.

Your way of explaining things is second to none on youtube. I wish every science channel was as good as yours.

This is so underrated, the potential here is mind blowing: properties, moldability, low tool requirement, low heat.

This video is amazingly informative and helpful. I was glued to the screen watching this. Thank you

Love this stuff. University I went to was involved in a "concrete canoe" completion and that always fascinated me. I also remember reading about a guy making a concrete trimaran to sail to Europe with. It really makes you think because we normally see concrete as being for roads, driveways, and buildings. Mostly wasting words for the algo.

I'll just say, I literally never know what to expect from your videos. So, so many half-finished projects and yet you always have a new and unexpected one up your sleeves. And yet I'm not disappointed. Very enjoyable stuff, as always.

anxiously awaiting the body armor construction and tests. love this channel.

This is the best video I have ever seen that talks about Dendritic Copper, Nano-scale Aluminum Nitride, Silicone Carbide, Boron Nitride, and Titanium Coated Diamond with epoxy adhesives! Keep up the good work!

34 minutes flew by so quickly when you're learning so many interesting properties regarding different materials and how they interact together! Also you should get a gimbal for those close-in handheld shots, those shaking takes away the experience when you are using such nice cameras already

This channel's content has been on my to do list ever since I've discovered it. So many awesome things to do, brilliant projects to delve into and research. If this channel existed when I was 10, I'd recreate most projects and become a scientist... I'm sure this inspires a lot of kids, well, I hope, at least.

pretty cool to hear someone covering all this information in an condensed but elaborate manner. as a professional prop and mold maker i come across countless "experts" (eg. many youtubers) trying to frame their limited experiences as knowledge. you on the other hand make a VERY good job!

This guy is one of my hero’s. His kids are lucky to have such a knowledgeable dad. I never leave comments on videos but your content it definitively worth it. Thank you!!

Every video I watch by this man leaves me more impressed. He has an almost unbelievably rigorous and thorough way of approaching the subjects he covers, and he is equally gifted at communicating his knowledge clearly. There are a *lot* of DIY/how-to channels on KZfaq, but I can't think of a single one that is the equal of Tech Ingredients.

Oh MIghty Algo! Please accept my meager offering towards the success of this channel. Your humble servant, KZfaq Watching Guy.

I love how you guys take the "let's try different things together" approach and end up with very interesting materials. Plus the way you explain it makes it easier for people with a more theoretical background to understand. Cheers!

Fascinating stuff, I'd love to see some testing videos of the various epoxy composites in various applications. Seeing an aluminum weld vs carbon/epoxy bond in various tests (tensile, shear, impact, etc.) would be great. Bonus points for the armor compounds vs high velocity rounds (maybe even shaped charges?) There are several youtubers out there that might be interested in collaboration for these kinds of things. Love your channel, thanks for going so in-depth on all the subjects you cover.

Ti is my favorite channel - ever. It's near impossible to find engaging content, relative to the projects I'm working on, all presented with an eye toward the objective and scientific in one place, and yet, here it is. In recent months, I've found inspiration that has helped me to refine designs on LED lighting, sculptural art, PCB, audio design - and now I finally have a way to make whiskey that doesn't involve barrels! So many activities. Like a favorite restaurant or hiking trail - I want to keep it a secret, but we gotta share so these guys can grow.

I'ma just leave this here, THANK YOU, for being a teacher I never had, I have never been star struck in my life, but seeing u and your intelligence always gets me star struck.

This is like having a scientist giving good dad advice! So wholesome, thank you!

The idea of a ballistic panel is pretty interesting. It would be neat to see you make up some sample panels of your design and do a collaboration video with a channel like Taofledermaus. They test all sorts of viewer submitted items. I for one, would definitely watch both of those videos! Either way, very neat stuff; I learn a lot from your channel

Love this channel! Such a great attention to detail in your explanations which really shows off your understanding of the subject. You're a natural teacher and quite unique in that sense. The combination of theoretical, technical and practical aspects in your work is amazing. Cheers!

I love working with composites. Started years ago restoring an old boat. You are really pushing the envelope in at-home composite development. that's great to see. Too many 'makers' today see 3D printing as the solution to every type of home fabrication. 3D printing is seldom even an OK choice.

Your knowledge of epoxies, adhesives, solvents, materials, ...everything is amazing! I love your awesome videos, sir, and I love your subtle humor! GENIUS!!!

Wow! This channel is getting more interesting with every upload, keep it coming sir.

This is the most awesome, marvelous, exciting and extremely interesting

What a fantastic video that should definitely be on trending for how interesting and engaging it is. I especially loved the part with the green eco friendly basalt and the cutting edge technology diamond titanium safety material. Hope this comment help you guys beat the algo-rithm

It's like listening to the Great Teacher this guy. Thank you I've learned a lot in this video.

An experiment-based, systematic approach to material science for the DIYer. Brilliant! My favorite channel.

This is one of my favorite channels. Now you got me wanting to take molds of storm trooper armor so I can try to make an epoxy bulletproof suit to see if it would work. So many ideas so little time.

Great video, thank you. If you really want to strengthen an epoxy matrix, make some crystalline nanocellulose and then carbonize it. I'm making a super high temp Solar oven to cut out the cost of heating. Also, if you take it a step further and graphitize it, it becomes HIGHLY electrically conductive--similar to or better than many lab created graphenes. Interesting for playing around with with batteries and super caps. Pro tip, get a source of cellulose with an already high level of crystalline cellulose so that you can a very high quality, high percentage of crystalline content in the final product. Yes, you can technically use anything from newspaper to toilet paper to paper mail (no plastic) to sawdust to get a decently highly content, but if you use the former type sources, you can it in the 95% or so range.

You, and this channel are a treasure.

not only for the sake of the silly algorithm, not even afraid to repeat myself over and over again highly instructive program as usual. awesome, easy to understand, always a pleasure to watch. and always proud to share... THANK YOU SIR!!!

How to videos on certain methods and materials instead of just a single project are a great idea!! Love it

Thank you for this introduction. It is very interesting and the scientific explanations behind some properties are excellent. I would really like to see more of your ideas and results.

Very informative, i wonder if everyone who taught me gave these kind of explanations I'd be somewhere better too. :)

I'm always completely enraptured by the quality of the content you guys produce, and the range of knowledge you have. I'm very glad to be a supporter, and can't wait to be surprised with what you come up with next!

I just found your channel and as a boat owner/ repairer just get all exited to see your technology and technical aspects. It’s just great 👍

I absolutely love your videos. They aren’t clickbait attempts at gaming the algorithm, they’re clearly explained scientific discoveries and methods that can be reproduced by the common person.

I just commented on your last video, it being the 1st video of yours I've ever seen looking forward to each and every one to come! Thank you for what you do!😊

5:17 "Give it two good minutes of mixing" Oh now I get the food references ^^ Cooking really just is chemistry but with a treat at the end :D

i love this channel, so many things i didn't know i wanted to know. also: i agree, awesome, marvelous, exciting and extremely interesting.

I haven’t gotten through all your videos yet, but with each one I watch, I’m so impressed with the breadth and depth of your knowledge. Thanks for sharing. 👍🏻

a 34 min highly educational and valuable video performed in 45 min real time. That's some mad skills! Thanks for the high quality videos.

Very interesting! Would love to see an aluminium structure built using the carbon-epoxy mixture and what sort of stresses the joints could withstand vs. alu welding.

I was holding my breath when he opened the cup of silica. 😅 Great video. 5/5

Excellent stuff! Thank you so much!

here a am at 1:06 AM taking a class with you,always learning new thing about everything, these time epoxy and its variable, tank you , you really put thing easy to understand

Long time ago worked at an art studio/factory which specialized in making high end copies of museum pieces to send to schools when the original was too precious and fragile to send in person. Used many aggregates to simulate jade, argilite and bone. Mainly aboriginal art objects. When dealing with artists still alive and consenting to have their works duplicated, we often had the artist examine his original work and our master copy and not be able to tell them apart. Such a compliment to our work. We often used a vacuum chamber to remove any bubbles in our epoxy mixtures.

I really would like to see some of the ballistics testing on those pucks I have been playing with ballistic barriers for a long time this is fascinating stuff love you guys as always

Hi! very educational, really good! Will you make video about the thermal and "poor mans Teflon" epoxy? if so, when?

The camera work in your videos is absolutely outstanding - the best I've EVER seen in ANY instructional video. The content is top-notch too.

You, sir, are a legend. I have learned so much in 30 minutes and will be using more than 50% of it on real projects. Thank you, thank you, thank you.

I'd never heard someone enunciate ellipsis so well before. "It has working properties that are ... challenging"

Dang! That was just the intro!! Ahh cant wait to see more about this. Get into the nitty gritty [ ;) ] of all the material science.

Oooooh, I feel speakers video coming.

I've watched this video so many times to note all of the important epoxy techniques you mention here and in your other epoxy videos. I am getting started with building a composite plane which uses fiberglass / epoxy for the structure (Long-EZ and its derivatives for anyone interested) and had a few questions about epoxy techniques. The plans were made in the early 1980s, and I think product and techniques (should) have evolved since then. In part of the plans building the canard (small wing), the directions call for creation of a composite spar cap by layering glass/epoxy into a channel in foam. Instead of multiple pieces layered in, they lay in part of a larger trapezoidal cutout, and then fold it over multiple (11) times to build up the layers - each layer getting shorter, widthwise. This is described on page 10-5 of the Long-EZ plans (or page 60 of the 174-page pdf which can be found online). I'm just some fool on the internet, but this process seems unnecessarily complicated. I'll of course follow the directions, but I can't see what this adds to the process that having premade strips of fiberglass cloth doesn't solve. Would that be an acceptable change without sacrificing stability / strength / stiffness? Second question: regarding fairing, is there are pros or cons to the hollow glass microbeads or the phenolic microballs? The original calls for different fairing compounds over the years, eventually settling on dry polyester fill. Since wings will regularly flex and you mention in one of the other videos that polyester is stronger, but only once - glass based fairing epoxy sounds like the way to go. Last question: when laying the last layer of glass down on the outermost layer, adding the graphite/aluminum/dendridic copper makes for a more UV resistant epoxy layer. Is there a good ratio by weight or by volume to go by here? Since this will be a plane, UV and heat from the sun will be concerns. That's why almost all glass/epoxy composite planes are painted white. Maybe adding one or more of these powders will allow greater variation in color options. I would also be interested in looking at a thermal cure epoxy for the higher heat resistance. Anyway, thanks again. Your content is consistently great, and I can't tell you how cool / valuable / helpful your videos have been.

Sir! Keep your good work. Both of videos I watched were longer than I liked, but both had the hidden jewel of a detail that made viewing time worth it. Keep the details. The extra things I learned were engaging. You remind me a little bit of Bob Ross.

23:49 " looks like your cat threw it up " haha

"I will be using food terms to describe these mixtures." ... "Hairball."

Food references, ey? "tends to be more like a jelly, kinda like snots." Well that got outta hand fast

i like the smoothness and the invisibility of humour in the speech

I have used that exact technique with the sandwich bag for frosting cakes. Interesting to see the overlaps.

Outstanding video ! You're so deeply knowledgeable you must be a material physics professor, am I right ?

How is this information free? Like seriously. How is this man such an altruist?

i had to remind myself that i didnt have to hold my breath when you added the silica

Just discovered this channel this week. The projects are always interesting, but the thing that I find truly astounding are your explanations of the physics/chemistry/engineering behind everything. Every one of your videos feels like I am getting years worth of working knowledge from an expert condensed into 30 minutes. Looking forward to watching the whole catalog, and I will definitely be telling all my peers about your channel! Cheers!

You are a great teacher ! Simple videos with lots of information and explanations of why things happen. THANK YOU.

Love your videos but had to pause at 9:25 to leave this comment. If it’s important to wear a mask, please wear it (same with any other PPE). The example you set is important, and you can always voice over later or explain after a given step.

I shot an email with link to Burlsart, a guy making guitars out of epoxy and colored pencils as one example. Imagine a rock guitar out of actual rock?

Nooo! Now I need tubs worth of epoxy and a shelf of different powders. Otherwise I feel I'm not prepared for all the glueing demands that could appear!

This is (hands down) the best explained physics / chemistry channel. Really excellent stuff

This is at least the third time I've been researching or working on something and this guy already has a video on it. Subscribed. Appreciate the sometimes unconventional approach.

I was interested, then you said “ballistic”....go on...
