Nice you are doing this as a couple, seen other of your videos regarding the water glas, as a watcher i feel the love in the family, very nice Regards from Denmark
Don’t flush with water when using lye. Flush with vinegar. It neutralizes the lye. Keep a container at the ready. Also I recommend doing it outside because the fumes are caustic to your lungs. There are always fumes.
You are a truely a man of many talents. Love your channel. I am the only handy woman in my house, I am always wanting to learn new things. From Ontario Canada. Keep up the good work.
Thank you for the way you research, experiment, and share what you doing. I find many of your videos to be an inspiration, including this one (and next). I first started appreciating your videos via that earlier video on DIY AirCrete Gun and setup for $35. I am a tool guy, ... and I give you a major thumbs up, ... especially appreciate how you are looking out for younger folks, ... as including those heads up messages to folks on safety awareness! More Power to ya and Best Wishes on all your endeavors. ;+) Bill from Northern CAL
@@kathrynostergreen8480 How can you make it for 2 dollars a gallon unless you are getting ingredients donated to you? I'm a fan of DIY'ing, but there are times to do it and times not to do it, and besides just the total costs of the raw materials, there is also the time and safety issues involved. Getting it for 20 dollars a gallon is a good deal. With that said, it is good to know how to make it from relative "scratch" in case there is ever a huge price jump or lack of availability.
Good info! Especially if you go and price what proper refractory bricks cost. Heart attack stuff! Your comment about safety is so true. As a rule many only learn AFTER something goes wrong. I vividly remember the first time I used a plasma cutter on steel. So "proud' of myself! Gloves...and a pair of those slip on ankle height safety boots. I "forgot" about Murphy Law of Probality! Guess where the nice big FIRST blob of molten steel ended up? Yep.....into the boot on the side of my ankle. 😆😁 Talk about some fancy RAPID dance moves??? Talking loudly in a "strange" language?? Was a sight to behold....😂😉
You could save on the amount of heat needed by putting the silica gel in the water first and using the exothermic reaction from the lye to do a good amount of the heating for you. Depending on your exact concentrations of silica you might not even need heating but for richer mixtures you will probably need some.
Good comment . I do as you suggest . I water down my water glass quite a bit to mix with absorbing vermiculite and it hardens well and remains intact in the wood stove fire chamber
Hi I am looking for ne mold materials. I want to do lost polymer cast. So my initial idea is to use drywall compound and spread it on my 3D printed part. Then use sodium silicate sand mix for the rest of the mold. Finally burn out the polymer and pour. Can you refractory be used for tjhat too ? Does it break down with heat ?
Sir, I appreciate this video. I’m so glad that you’re after thinking about this before me. I’m looking to heatproof an improvised stove as well, and I’m brand new to the whole concept. But way of returning the favor, I’ve got a little advice for you. If you are working with sodium hydroxide or potassium hydroxide and you happen to get some on you, if it’s not water you wanna rinse with, it’s vinegar. It’ll neutralize it right away. After that, then you can hit the water. I’m a person that occasionally likes to make soap, so although I don’t use it so often and I forgotten a lot of the little bit that I took in university chemistry, this is probably the one principle that I can pass on with some surety. I’d sure appreciate it if you could see if you words about cleaning the pot so we can be safely used in the kitchen again. Because the cost goes up dramatically if I have to sacrifice a pot every time I do this. Thanks again.
Lye, or sodium hydroxide is used in food processing and isn't actually poisonous, in fact it is an extremely good cleaner, and very similar to the potassium hydroxide used in diy soapmaking. 'Mr. Clean' kitchen floor cleaner is 1% sodium hydroxide, and 99% water, basically. I can remember t.v. commercials showing an infant crawling across a kitchen floor that purportedly had recently been cleaned with that product. Sodium silicate is inert, and indigestible, and would pass right through a person if swallowed. The only real danger I can think of is repeatedly inhaling the dust particles of that and it's causing irreversible lung damage, during industrial applications. Between the sodium silicate and the sodium hydroxide, the most noticeable occurrence would be a very clean and shiny stainless steel pot. All remains of the water glass concoction are water soluble and will rinse away clean. 👍 Oh, and I'm so glad you mentioned the vinegar thing. Very few people are aware of it, I guess no one paid attention like we did in science class- hmmm?
@@markhonea2461 Sir, it occurs to me going back and reading these comments, that sodium hydroxide is a real problem if your children get into it. The other name for sodium hydroxide, is caustic soda. It can cause some pretty bad base burns, Although you don’t feel it right away the way you would with an acidic burn. I don’t know why I didn’t think to mention that last year, when I responded to your response As a matter fact, it seems to me that there was a woman from our church many years ago, whose husband was in medical school. They had three children and not much else. They worked a lot of hours any time they could get them, and she made homemade soap to sell, to augment the family income. She always made her sodium hydroxide solution and once it cooled, she secured it in the cabinet in the bathroom, where she had baby proofed the cupboard. Except on this one occasion, the children were quiet for just a little too long, and she found them in the bathroom, having found a way to get into the secured cupboard. The baby drank the sodium hydroxide, And she could see what it happened. The baby had to be rushed to the emergency department and was admitted to the Children’s Hospital. He wasn’t expected to live. The burns were extensive from the mouth to the oesophagus and down through. The baby was given a blessing, the next day the burns were healed. So that little one is doing OK nowadays. Anybody who wants to take issue with me because of the religious aspect of this, can hold your peace. The whole point was, the baby drank the sodium hydroxide which had cooled down to room, temperature, and the damage was so extensive that the little fellow was not expected to live. Dissolution is a lot more than 1% lye. And the other thing that’s good to remember, when you go to mix it, is to Add to the water in a very well ventilated Situation. Not only is the reaction violently exothermic as you know, but it also damaging to mucous membranes and decomposes proteins. so it’s grossly misleading to say that it’s completely safe. It is used as a buffer sometimes, but it’s not something that’s good for a person in any way, shape or form, to be subject to in this form, and this concentration. I’m making these corrective comments out of an abundance of respect and caring. No disrespect whatsoever.
As a side note; When I lived on a small farm in the 70's Water Glass was sold cheaply in the local grocery store and was commonly used by farmers to store extra eggs from the summer to use during the winter. We would fill a 5-gallon crock about half full of water and add a quart of water glass, then drop in the extra eggs as we got them throughout the warm months, covering with a piece of wood for a lid and stored in the cold cellar. We would enjoy the eggs all winter, no refrigeration needed. The water glass would seal the eggshell keeping any O2 out. Note: You have to keep them from freezing. The yokes would get flat when cracked into a pan, so not so good for fried eggs but plenty good for scrambled eggs and indistinguishable from fresh eggs for baking.
Laboratory grade sodium silicate is only about $15 a pint and is available online to anyone with a CC#. So much better than using kitty litter mixed with who knows what kind of aromatics and filler
I was wondering that , liquid glass that's what I know it as, it's for sealing head gaskets as I say, now that would be pure sodium silicate correct ? They also used this to seize the motors in the cash for clunkers too I believe
Could you please tell me, if your Water Glass is solidifying after you have put it in the bottle. Also in the 1st part of putting Caustic drain cleaner to water, are you heating the pan on the Stove or not.
@@undernetjack thanks for the info, I asked because a Guy here in the UK who made W/G, live on Video, said, 'he had to tighten the tops of his container real tight, as when air got to it......it turned into solid glass very quickly, so he was using more water to start with and then thinning down at least 65% before bottling it up. Watching the Video, I saw he cooked from the very beginning of the process, the mixture over a very high heat, and later he could only use roughly 3/4 of the amount of Cat litter, required in the Ingredient measurements. So my query is, must the water be and kept on a rolling boil when Caustic Soda is added to it!!!
He is making this to insulate his heat riser on his rocket stove. The more heat that is retained in the riser the cleaner/more efficiently the wood will burn. Also the "rocket" sound is made from a strong up draft... or hot air rising quickly. A better insulated heat riser will burn hotter. ( insulated heat riser will help burn off more of your creosote. )
For my general knowledge, If we mix water glass in water and then spray it on Table , after it is dried will it leave sharp glass pieces ? And when it is wet is it also an adhesive type Material?
That's a shockingly high molar concentration you have there. I'm surprised you use so little water. My usual "small" batch is 160g NaOH, 240g silica, and 400mL water, and it ends up about as viscous as corn syrup.
What is the difference between Sodium Silicate 40% (Water Glass for pottery - $19.99/gallon) and creating this kitty litter stuff? I have Red devil Lye(for soap making) and it's not too cheap so buying the premade water glass seems cheaper but for pottery it's only 40%. Is this waterglass that you make 100%? Just curious to the cheapest way because the ready made gallon jug(40%) seems a lot easier. I'm building the insulation mound for a Mass Rocket Stove and have found the waterglass/perlite/sand formula to be a great, low-cost insulator/refractory method for the firebox in my stove....
A long time . On UA-cam video host purchased water glass from a chemical supplier and apron arrival was practical a solid . The UA-cam showed soaking the almost solid water glass in water to get it softer. I personally have keep it a year in an open bottle and though it became thicker water added can thin it back out
I just found where I can get silica gel cat litter, so I 'm going to try to make some water glass this weekend do you have any idea howl ong the shelf life could be?
A year . It may dry out. Just add water. Good as new in my experience.. for me the key us the hardest to get at a reasonable price. as cheap as $4 in pint bottles try a independent hardware store like service star affiliate . The big box stores seldom have it and when they do its $7
I probably will be building a batch rocket stove using 1" ceramic fiber board for the burn core, like the Walker stoves (Peter van den Berg type) from broaudio. The board needs some help otherwise just the normal process of loading wood will eventually damage it. Could I use water glass to toughen the ceramic board, either by applying to it's surface or soaking it ?
Tonzarama You could get away with facing the board with 1/4" to 1/2" hardbrick slices in the firebox of the Walker core. It gets so hot it shouldn't matter.
Thanks Jeremiah for the feedback. I just saw a new design from Peter van den Berg called the DSR (double shoebox rocket) it looks promising. So again I may be changing my design plans, be well.
Tonzarama That does look like a good one. I will wait for a couple more builds of it before I jump off of the walker core. The double shoebox would be awesome in a brick shell!
If you get any lye on your skin you can neutralize it with sulfuric acid. WAIT!! JUST KIDDING!!! Actually a splash of vinegar, any type, will very quickly neutralize most anything like that. And vinegar isn't dangerous to get on your skin. Lye is not too particularly dangerous to skin but can not remain there or you will get extreme drying and damage , so either water, until you don't feel slimy anymore, or a bit of vinegar and be done with it.
Forty years ago, I only used lye for making hydrogen. When mixed with water, and aluminum is added, the stuff reacts "violently". Even after exercising all precautions, the procedure always made me nervous. The heavy glass bottles I used got blistering hot. I always put the bottles in a bucket of sand during the process. But I haven't done it in decades, and have no desire to do so. I found out more recently about pure ash from a fire, soaked in water for a long period, becomes highly alkali. Not sure of the concentration.
My research into soap making led me to using wood ash to make lye; float an egg in the soliution of wood ash and water, until there is about a quarter size of egg floating above the surface. this was the strength for soap making.
Thank you! Will use this for sure! I’ve seen already prepared sodium silicate for sale and they always emphasize “fresh” or “date __x__x__ prepared” so I assume there’s a shelf life?? Does it actually become less effective? Or probably just absorb a little atmospheric humidity being hydrophyllic? (Which seems like it shouldn’t be a problem) ???
Sodium silicate reacts with CO2 and starts to cure with exposure to same. Most container materials (more so plastics, not metals) are fairly permeable to CO2.
Great info! Could you use the foam with castable refractory to stretch the material (and the cost of it ) to cast like a pizza oven dome? your thoughts?
Can we get some concrete numbers (no pun intended) as to the thermal capacity of this chemical mixture? I don't want to even consider going to this much trouble if my heat riser is going to crack in 5 years anyways
The silica gel kitty litter that you're using him as a shit ton of cobalt in it. I would be wary love it there are brands that have almost none By the way you don't need distilled water to make water glass regular roll tap water will work fine you're going to boil any chlorine out of it
How do you know it has cobalt in it. ? Perhaps the blue Crystal's is considered cobalt blue as a color. But my package of crystal kitty litter says sodium silicate as the inqredient
Waterglass isn't really all that expensive. It is often sold for making concrete more water repellent. I got a gallon jug of Rutland brand for around 20 dollars or so. Then, you can often source potassium silicate in powder form as a plant food. You just mix that with the right amount of distilled water and you have a potassium watergalss which in many ways is quite similar to the sodium silicate. The molecules are a bit smaller though. By the time you buy all the ingredients, factor in the cost of heating and time to make--you're really not saving much by making it yourself, and I say that as a fan of making things myself to save money.
I would at least double the cost of what he states @ $4 per bottle of lye. . A whole gallon to me is quite a lot I have made a half gallon and it took 3 or 4 bottles of lye. But I dilute the resultant water glass with several gallon of water when mixing in the aggregate
Not sure about this homemade solution, but the stuff I bought in a bottle, when stored with the cap tightly closed and in a stable, temp/humidity controlled environment, well it's stored well for a couple years already at this point.
Its better to grind the silica gel to increase the surface area and add it a little at a time. If you dump a lot in at once it tends to clump together in big lumps like icebergs ;) Store bought sodium silicate generally has a SiO2:Na20 ratio of 3.2, yours will be around 1.936 assuming the lye is 100% pure
Me and everybody else has tried the powder silica gel trick and we all get your iceberg effect. So grinding doesn't help at all . For fastest mixing I use it right out of the bag
That's so weird. I hardly had any issue mixing up my sodium silicate. It heated - but didn't boil - the water. When I used the dessicant packs, it took a good bit of time to even mix up. And I added both dry ingredients together first and then the water. But if you want to see a reaction that will really get a reaction from you...... make sodium sulfate instead, AKA replace the kitty litter with sulfuric acid. My advice, cover ALL skin, and wear a respirator and eye protection. Because it goes BOOM. Consider the reaction with the distilled water, and think it's a neutral compound. Replace that with a super acidic one. Most volatile reaction I've gotten with my backyard chemistry. Oh, and best source of sulfuric acid: Betterbuilt Drain Opener. Lab grade sulfuric acid for $5.96 (or $400 from a lab)
Silica Gell is also used for drying flowers. You can find it at craft places. Dude you might want to work on your editing, you could have cut this by a third and not lost a thing.
Thanks for sharing, is my you tube screwing up or do your videos just end, with no conclusion ? I do like your channel but it just stops without seeing you use what you just made.
It sorta just picks up in the next video. He'll tell you how to make a left turn, then in the ext video he'll show the left turn and where he made it why he needed it. but the left turn video is about making a left turn.
not sure how much you are spending to make it but labor and time isn't cheap this is 100% water glass for $27.00 Rutland 1 Gal. Water Glass Cement Floor Sealer Gallon Jug
Water+OPC(ordinary Portland cement) forming a slurry+foam=aircrete which needs to be cured(dried) slowly after pouring into a form. Darrin keeps mixing up the words "cement" & "concrete". Concrete= cement+water+aggregate. I love his experimentation. How else can we learn, invent, innovate? All "thought experiments" have to be tested to be valid.
Cobalt contaminants, I think. They're used in more expensive "crystal" cat litter and desiccant packs as a moisture indicator. That, or it could well just be blue dye from the cat litter.
interesting. . .I was just reading about hydrogen gas. Is that the same as molecular hydrogen, H2? And yours is the second comment so far that mentioned it. Is it normally considered to be a bad thing?
True eye wear is a good recommendation . A nearby . Very near tub of tap water should be near . Very near to wash ones face. . Thin latex gloves is a good idea or just a plastic bag. In a pinch I have used teflon aluminum pots , used with sucess. Pyrex glass measuring cups I do not like because on shattered from the combined heat plate and internal heat from the lye water chemical action . Stainless steel is a preferred Choice . I dont bother with the heat plat any more . The heat from the chemical reaction is adequate to combine the key water and kitty litter Pulverizing the kitty liter . I and many others have tried that . It does not speed up the process. It greatly slows it down . Best to throw out and start anew with kitty litter directly from the bag

Have no clue why you needed this, what it has to do with the rocket stove, or how it will be used, but it was fascinating.
It is very interesting stuff, and we have some videos coming of how we use it.

I'm building the insulation mound for a Mass Rocket Stove and have found the waterglass/perlite/sand formula to be a great, low-cost insulator/refractory method for the firebox in my stove....
Could you use fire bricks as your riser tube please ?, paul
Yes
You are making only water glass, but not the refractory mix itself. What ingredients and ratios do you use?
How much water glass do you use with one pound of perlite?
Water glass what is the temperature rating?
How long will waterglass keep before it can no longer be used?
A long time . On UA-cam video host purchased water glass from a chemical supplier and apron arrival was practical a solid . The UA-cam showed soaking the almost solid water glass in water to get it softer. I personally have keep it a year in an open bottle and though it became thicker water added can thin it back out
I just found where I can get silica gel cat litter, so I 'm going to try to make some water glass this weekend
do you have any idea howl ong the shelf life could be?
A year . It may dry out. Just add water. Good as new in my experience.. for me the key us the hardest to get at a reasonable price. as cheap as $4 in pint bottles try a independent hardware store like service star affiliate . The big box stores seldom have it and when they do its $7
I probably will be building a batch rocket stove using 1" ceramic fiber board for the burn core, like the Walker stoves (Peter van den Berg type) from broaudio. The board needs some help otherwise just the normal process of loading wood will eventually damage it. Could I use water glass to toughen the ceramic board, either by applying to it's surface or soaking it ?
Tonzarama You could get away with facing the board with 1/4" to 1/2" hardbrick slices in the firebox of the Walker core. It gets so hot it shouldn't matter.
Thanks Jeremiah for the feedback. I just saw a new design from Peter van den Berg called the DSR (double shoebox rocket) it looks promising. So again I may be changing my design plans, be well.
Tonzarama That does look like a good one. I will wait for a couple more builds of it before I jump off of the walker core. The double shoebox would be awesome in a brick shell!
Tonzarama Keep in touch with me about your build!
Love the channel fella. Could you tell me in detail why use sodium hydroxide in the mix ??? Thanks
SiO2+NaOH = NaHSiO3
@@sergeyp.7985 Thank you Sergey for the formula to understand the chemical why. Peace too.
If you get any lye on your skin you can neutralize it with sulfuric acid. WAIT!! JUST KIDDING!!! Actually a splash of vinegar, any type, will very quickly neutralize most anything like that. And vinegar isn't dangerous to get on your skin. Lye is not too particularly dangerous to skin but can not remain there or you will get extreme drying and damage , so either water, until you don't feel slimy anymore, or a bit of vinegar and be done with it.
Forty years ago, I only used lye for making hydrogen. When mixed with water, and aluminum is added, the stuff reacts "violently". Even after exercising all precautions, the procedure always made me nervous. The heavy glass bottles I used got blistering hot. I always put the bottles in a bucket of sand during the process. But I haven't done it in decades, and have no desire to do so. I found out more recently about pure ash from a fire, soaked in water for a long period, becomes highly alkali. Not sure of the concentration.
Wood ash produces potassium hydroxide (KOH), not sodium hydroxide (NaOH).
As Sergey Plisov said: SiO2+NaOH = NaHSiO3
My research into soap making led me to using wood ash to make lye; float an egg in the soliution of wood ash and water, until there is about a quarter size of egg floating above the surface. this was the strength for soap making.
Did you add the distilled water??
Thank you! Will use this for sure! I’ve seen already prepared sodium silicate for sale and they always emphasize “fresh” or “date __x__x__ prepared” so I assume there’s a shelf life?? Does it actually become less effective? Or probably just absorb a little atmospheric humidity being hydrophyllic? (Which seems like it shouldn’t be a problem) ???
Sodium silicate reacts with CO2 and starts to cure with exposure to same. Most container materials (more so plastics, not metals) are fairly permeable to CO2.
Great info! Could you use the foam with castable refractory to stretch the material (and the cost of it ) to cast like a pizza oven dome? your thoughts?
i like the food ideas also!
So Interesting !
what about those handwarmer things - i think i heard that was the same stuff, or at least it might be similar enough to work for what you need.
I dont think so usually firmly for hand warmers is sawdust and charcoal
Do you think it would work on a Adobe floor.
No . Too expensive
Always work with substantial ventilation with these kinds of chemical reactions. Outdoors or with active exhaust fans if you're indoors.
I suggest wearing a respirator as the fumes may be toxic.
Can we get some concrete numbers (no pun intended) as to the thermal capacity of this chemical mixture?
I don't want to even consider going to this much trouble if my heat riser is going to crack in 5 years anyways
It's going to crack within five years . Make your riser so it can be inspected yearly and disassembled
You kept saying you had to dilute your water glass. What did you dilute your mix with?
With distilled water.
This is a stupid question... Your not reusing the cook pot after this for food are you? love your video's..
No, this is a pot bought at a second hand store to use in the shop, and shop only!
The silica gel kitty litter that you're using him as a shit ton of cobalt in it. I would be wary love it there are brands that have almost none
By the way you don't need distilled water to make water glass regular roll tap water will work fine you're going to boil any chlorine out of it
How do you know it has cobalt in it. ? Perhaps the blue Crystal's is considered cobalt blue as a color. But my package of crystal kitty litter says sodium silicate as the inqredient
@@bobbrawley2612 because just a color similar to cobalt blue in nature wouldn't be the reactant but Cobalt would.
Do you add Aluminum Oxide? If yes at what ratio?
some say as much as 60%
Not really necessary for temp under 2000° Fahrenheit. Right?
Waterglass isn't really all that expensive. It is often sold for making concrete more water repellent. I got a gallon jug of Rutland brand for around 20 dollars or so.
Then, you can often source potassium silicate in powder form as a plant food. You just mix that with the right amount of distilled water and you have a potassium watergalss which in many ways is quite similar to the sodium silicate. The molecules are a bit smaller though.
By the time you buy all the ingredients, factor in the cost of heating and time to make--you're really not saving much by making it yourself, and I say that as a fan of making things myself to save money.
Quick question, what do you think the cost is to make a gallon of water glass?
it costs me about $6.00 for 1/2 gallon or $12 /gal
I would at least double the cost of what he states @ $4 per bottle of lye. . A whole gallon to me is quite a lot I have made a half gallon and it took 3 or 4 bottles of lye. But I dilute the resultant water glass with several gallon of water when mixing in the aggregate
@@bobbrawley2612 Silica cat litter has gone up in price.
How long will the water glass keep?
Not sure about this homemade solution, but the stuff I bought in a bottle, when stored with the cap tightly closed and in a stable, temp/humidity controlled environment, well it's stored well for a couple years already at this point.
Use vinegar to neutralize (NaOH)2 water will take for ever...Dissolve the caustic outside or in a well-ventilated area.
Anything lightly acidic will work.
what is the self life of this mix?
Life long I suspect if keeper air tight
Funnels are useful for preventing that...
whats the ph of the final solution?
easy Hitler
hello can i use this to make my pizza stone and wall ? i want to build my pizza oven . thank you
I would think so . Sodium silicate was used to coat eggshell as a preservative before the age of refrigerated
Its better to grind the silica gel to increase the surface area and add it a little at a time. If you dump a lot in at once it tends to clump together in big lumps like icebergs ;) Store bought sodium silicate generally has a SiO2:Na20 ratio of 3.2, yours will be around 1.936 assuming the lye is 100% pure
Me and everybody else has tried the powder silica gel trick and we all get your iceberg effect. So grinding doesn't help at all . For fastest mixing I use it right out of the bag
1:54 Some kitty litter is pure Slica Gel
Is the liquid glass found at automotive parts stores sodium silicate ?
Thanks for the video... However please use a funnel people. Hate to waste the hard work!
Habari yako rafiki yangu kuna jambo nataka kujua kutoka kwako tafadhali naomba uniasidie.
You ALWAYS add water to bases, not the other way around.
That's so weird. I hardly had any issue mixing up my sodium silicate. It heated - but didn't boil - the water. When I used the dessicant packs, it took a good bit of time to even mix up. And I added both dry ingredients together first and then the water. But if you want to see a reaction that will really get a reaction from you...... make sodium sulfate instead, AKA replace the kitty litter with sulfuric acid. My advice, cover ALL skin, and wear a respirator and eye protection. Because it goes BOOM. Consider the reaction with the distilled water, and think it's a neutral compound. Replace that with a super acidic one. Most volatile reaction I've gotten with my backyard chemistry. Oh, and best source of sulfuric acid: Betterbuilt Drain Opener. Lab grade sulfuric acid for $5.96 (or $400 from a lab)
Wished to see whatever disclaimer that using chemicals is a different beast, and therefore wearing savety stuff like eyeprotection is a must.
❤❤❤❤❤
I didnt see the refractory, must have blinked
Silica Gell is also used for drying flowers. You can find it at craft places.
Dude you might want to work on your editing, you could have cut this by a third and not lost a thing.
Thanks for sharing, is my you tube screwing up or do your videos just end, with no conclusion ? I do like your channel but it just stops without seeing you use what you just made.
It sorta just picks up in the next video. He'll tell you how to make a left turn, then in the ext video he'll show the left turn and where he made it why he needed it. but the left turn video is about making a left turn.
not sure how much you are spending to make it but labor and time isn't cheap this is 100% water glass for $27.00 Rutland
1 Gal. Water Glass Cement Floor Sealer Gallon Jug
Really like your videos but this porno music from my Dad's old VHS tapes....why?
Water+OPC(ordinary Portland cement) forming a slurry+foam=aircrete which needs to be cured(dried) slowly after pouring into a form. Darrin keeps mixing up the words "cement" & "concrete". Concrete= cement+water+aggregate.
I love his experimentation. How else can we learn, invent, innovate? All "thought experiments" have to be tested to be valid.
SiO2 is cheap tho, better than cat litter
You’re Honey and she’s Sweety
those packets you are showing in the jars are oxygen absorbers!
That doesn't look pure, something is really polluting the final product
@9:23
Cobalt contaminants, I think. They're used in more expensive "crystal" cat litter and desiccant packs as a moisture indicator. That, or it could well just be blue dye from the cat litter.

I believe the first aid requires flushing with vinegar not water!
Not hard to find and not expensive. I pay les than 5 dollars a quart for it
Never react NaOH in an aluminium vessel, because it creates hydrogen gas. OH THE HUMANITY!!!!
interesting. . .I was just reading about hydrogen gas. Is that the same as molecular hydrogen, H2? And yours is the second comment so far that mentioned it. Is it normally considered to be a bad thing?
You said 1500 ml. while the recipe says 500 ml.
He made a triple batch. He said that in the video
I mix it by the reaction or lack of reaction . Not measuring . Like mixing concrete to a desired slump test.
I smelled the safety talk coming after the lye ... useful, but nasty dangerous.
True eye wear is a good recommendation . A nearby . Very near tub of tap water should be near . Very near to wash ones face. . Thin latex gloves is a good idea or just a plastic bag. In a pinch
I have used teflon aluminum pots , used with sucess. Pyrex glass measuring cups I do not like because on shattered from the combined heat plate and internal heat from the lye water chemical action . Stainless steel is a preferred Choice . I dont bother with the heat plat any more . The heat from the chemical reaction is adequate to combine the key water and kitty litter
Pulverizing the kitty liter . I and many others have tried that . It does not speed up the process. It greatly slows it down . Best to throw out and start anew with kitty litter directly from the bag
You should at least give credit to the guy that did the original one that you're copying your using every word for word what he did.
It was invented in the early 1800's I really have no idea who you are talking about.
@@HoneyDoCarpenter there are tons of videos on the crystal kitty litter formula . I guess he is talking about one of the other guys videos
@@bobbrawley2612 no I'm talking about the one that he learned it from he does everything exactly the same word forward even uses a knife to stir it like the other guy did. LOL it's funny I see so many people do this and not give credit. How hard is it to give someone credit? There's no way that he could accidentally get this video exactly the same giving the same exact information and even using a knife to stir the thing a knife is probably the worst goddamn thing you could used to stir inch and a half of liquid with but the other guy did it so he did it LOL give the guy credit come on
Craft paint shops should have it???
