Homemade sodium silicate (water glass)

- I make sodium silicate at home with drain cleaner and desiccant packs. I want this substance as a high temperature adhesive for refractory lining.
Chemical ratio:
200g of sodium hydroxide
300g of silica gel
500ml of water - Наука та технологія
*Use a stainless steel pressure cooker. Make it in about 45-90 minutes (@15 PSI) from clean kiddie- play-box sand and sodium carbonate with minimal water added. Using too much water kills the reaction. Add only enough water to cover. Ratio: 2 parts sand to 1 part sodium carbonate with enough water too cover. That's how PQ Corporation makes the real stuff, I used to work there. This will yield an "N" grade sodium silicate product with a much milder alkalinity than your mixture which is too radical, too much lye! This yields an 80% reaction and the remaining 20% sand is used in the next batch. The 80% sodium silicate is decanted off. Eventually an excess underacted sand is deposed of due to high alumina, magnesium or calcium content, not all sand works but its good enough to make tons per hour at 80% yield in our 300 gallon STAINLESS STEEL pressure cookers.*
Is that all - ! Can't wait to do my pavers
I tried your method my sio2 source was crushed mirror powder, iam using kitchen press cooker about 14 psi but iam not really sure it was sodium silicate or not because it feel so slippery like washing soda itself so i couldnt tell the differences, hence after some time it become jellified
Any idea abt Stannous Octoat making pls
you miss out the stage where the silica sand and calcium carbonate are calcined [roasted] together at a temperature of 1100 degrees centigrade. Use that as your feedstock and your reaction will work
@@bigoldgrizzly This. You need to calcine it. Compounds don't react in water.
Pfff. You have sodium hydroxide? That's a total lye.
+Natethesandman1 hardy har har!
+Natethesandman1 that joke was caustic.
It appealed to our baser instincts...
Really? It brought out my more acidic side...
Someones self esteem just went down the drain
@ Nick Pierson I agree. Sodium Hydroxide, (aka Lye, Caustic Soda) is a very corrosive material in its concentrated form. It will melt simply by absorbing humidity from the air. On skin, it melts and seeps into the pores and can cause third degree burns. In the eye (to my own sorrow, though I wasn't blinded) it will store in the tear ducts and as the eyes' defensive discharge of moisture tries to clean out the eye, it causes persistent damage to the eyeball. I had 60% of my eye burned by 1 single bead finding its way into my eye. The point: EYE PROTECTION IS A MUST. If you neglect the use of gloves or any other PPE, at least protect your eyes.
NaOH in the eye must hurt like hell, didn't it
Just a comment. You can buy 20lbs of pure silica gel for $10 it's called crystal kitty litter. Then the lye is also cheap. I can't believe I've been searching for "high temperature glues" literally for months now ... I've used every "high temp" glue at Lowes. They all break down at 500F. Then finally I find this shit. What a miracle science is... this is EXACTLY what I've been looking for.

Hi, and same boat.. thanks for the heads up on the cat litter, $20 a kilo for gel on ebay, $1 a kilo for cat litter.. o.O
I'm set to build once I can find a substitute for the aluminium oxide.. can I use fire-cement instead or have you any advice? appreciate you help mate.. :)
Julio says Yes, absolutely. Fire cement will work fine. They make it just by adding talc (baby powder/magnesium silicate) to silica, sodium silicate with a low % of lye. You won't have ANY melting issues with either fire cement or making it yourself at home.
The REAL problem here isn't melting points as much as thermal expansion and curing things properly. So if you want my best advice to avoid cracking/degradation... you really just need to preheat the forge everytime you use it. And let it dry real good for like a week before firing it up otherwise you'll see a yellow flame, steam and the lining WILL crack very fast.
When preheating just run propane through the forge (lit) without any assisted air for 2-3 mins. Then you open the air cover/valve. And also when you shut the forge off always make sure some type of cement or metal lid is on it. Otherwise you wind up with white hot fire cement hitting "cold" air and you'll literally hear the cracking as it cools down.
It's these simple, but time consuming practices most people skip which leads to their forges breaking. And even when you follow best practices 100% all forge linings eventually do crack. Even if just a hair. When that happens all you need to do is respackle a bit of firecement. Gluck. ;-)
+Robert Cece Hey just got your message, thank you for the advice, >> Update: right now I've 25kg of fire clay, 25 lt of Perlite, 3 or 4 kilos of silica gel + powdered caustic soda..
I have used sodium silicate to repair two engines that were leaking water into the cylinders and also to repair a leaking heater core on a 2002 chevy S-10.
The removal of that heater core takes removing the entire dash of the pickup.
I have done this before . It is a pain in the A
OMFG - WEAR GLOVES & EYE PROTECTION, PREFERABLY A FULL FACESHIELD! THIS PROCESS IS HIGHLY EXOTHERMIC (IT GETS VERY HOT)
+RTOHIO The recipe for the lining I did in my homemade foundry has no plaster in it and it set up just fine, just took longer. You could dump it down that space sure, but liquid is not the consistency this recipe works as. More like a damp soil. Will the insulation be exposed to rain / snow? Perlite is very absorbent. I have seen rocket stove chimneys insulated with strait perlite, just poured in the gap.
Go to the Ceramic Supply Store and buy a bottle. It is Cheap. Try Trinity Ceramic, Dallas T x ONLINE
You can get 100 percent water glass at fireplace stores for about 38 bucks a gallon and no home chemistry project!
Dean Carder It is a simple and safe process, and also I can make a whole gallon for less than 10 bucks.
+William Drake is it the liquid gasket cement?
100 percent water glass is a solid, that is sold by weight. The solution sold at those stores is water glass mixed with water. For most people, making it out of lye and silica gel represents a very significant saving that is well worth it.
Nice! I used this procedure to make sodium silicates as geopolymer reagent. I mean the dessicant is made from waterglass and with this we make it back into waterglass.
@Tyler Knight This would make a brittle glue, better is pure orange oil and styrofoam. Look at this video from GreenPowerScience d-limonene polystyrene DIY Nano fiber micro-weave antimicrobial collagen growth meshwork styrene
Hi I want to know how they make glue for carton with sodium silicate...you know how??
clkindred I have a question? Can you make this using a oven? And if so what temperature? Thanks
For those who don't know where to find Silica Gel material in its bulk for for dirt cheap check out your local building supply stores concrete and masonry section.
I just picked up a 50# bag of Silica sand/Quartz sand (same SiO2 chemical structure as silica gel pack SiO2) for $6.
Will there be impurities in the silica sand/quartz sand?
Crushing your silica gel makes the reaction go faster. And it isn’t dissolving, it’s reacting.
How did you get your desiccant packs. Any easy way to get them, or did you buy them
Work With Nature You can buy silica gel kitty litter very cheap and it's the best source for silica gel if you don't already have some.
clkindred
What brand, Name etc.. and where do we find it? Thanks for the info...
Walmart has it, it's called "mimi litter" and it's about four dollars for four pounds.
Look in the floral section of Hobby Lobby or Michael's. I bought a five pound bag for $14
@@clkindred y
Do you know how long this can be stored and still be usable? Example: If I make too much can I store the remainder for a while (a year or more) and it still be usable? thanks
As long as it stays dry, it will last almost forever. If it get wet often or left out in rain it will dissolve,,,, it can be dissolved with lots of water left for a long time. Even when a 6" C-clamp fell into it and was puller out and left to dry,, I just put it in water and a couple days later it was perfect.
@@offgrid-j5c I thought that once the sodium silicate reacts with either an acid or CO2, it basically loses it's sodium ions and turns into straight glass? If so, then any amount of water shouldn't affect it? Am I missing something?
@@justinw1765 ,,, It will Never become actual Glass! It is called "water glass" (2 words) because it is clear like water and protective like glass. (as with chemicals). I made mine using silica gel from cat litter,, (100% silica gel ,, with blue dye, the dye dont matter). I used sodium hydroxide (lye) crystals added to water and heated to almost boil,,, then remove from heat and pour in the silica gel,,, it will get hot then by itself as the chemicals react. Be very careful,, it gets hot. Do it in a well ventilated area,,, the lye fumes are baddddd! Sodium silicate has been used for hundreds of years,, they even use it to preserve chicken "eggs" back in the day. They just drop the eggs into the water glass liquid and eat them months later. When I made mine I added it to sand and made a "refractory" cement for my homemade forge. Works awesome,,, my first brick was 1in thick x 4in x6in,,,, when it was cured I could hold it on my hand and run a propane torch to it for 5 minutes and the heat never transferred to my hand,,, it is a awesome insulator. It had to be dried and cured for fire cement. If you spread it onto something it will turn white as it dries and cures. That takes some days depending on the temp and humidity. but as I said,, it is 100% water soluble until it is "Cured". Brought to a very high heat like a furnace,,, it will not dissolve with water after that!! Cured will be a hard brittle substance,, that does NOT react to heat or watere and is great for kilns,, ovens and forges!
@@offgrid-j5c what sand did you use?
What proportion for brick?
Was the brick porous or just solid chunk.
How is it holding up?
Thanks.
@@khayyam741 I used sand from Home Depot. Just play sand. It is Not beach sand,, that doesn't work as well because the sand is all little round beads, where crushed sand has sharp corners, is rough and locks together better the round sand. I hade mine to be moldable. I hold a handful and squeeze it tight then see how well it sticks together. I then layed it 2in thick all around the inside of a BBQ body. One of those $19 dollar types,,, lol. I built a coal forge from it. It was not very durable at first,,, till I figured out the it get really hard and durable after it has been dried,,, not in the air but by heating it. I had to put the BBQ body with the waterglass lining on top of a wood fire for several hours to "set" the glass. After that it was and still is great!! My first try and experment was a "brick". 2.4in thick 5.75 long 3.25 wide. It was awesome for heat reflection. Again I was experimenting and put the formed soft brick In my wood stove,, as I was impatient and tried to "set" it that way,,,, did well on the bottom of the brick, against the fire but not so good on top of the brick where there was less heat. When I took it out and let it cool teh top area fell apart but the bottom stayed tightly set. It was only 1in think by then. I used a propane torch ,, held it in my hand and put the torch to if ,,, for 5 fill minutes before I could feel any heat at all. It worked great. If done with "patients" in a good oven then it could be equal or better than store bought refractory bricks. Cheers!
Thanks for the clarification. I'm going to try and make the insulation you made with permilite, just wanted to make sure I understood correctly, Thanks!
I have a question, I'm looking at refractory additives to cement for a pizza oven, I watched you forge video which led me to this, but instead I just bought some...then I researched alumina..and then I came across a spill absorber called magic monkey..labeled as alumina silica. Question will that work as an alumina additive and will the silica benefit it more. I've seen refractory brick made out of alumina silica. Question would that product work..also adding in the water glass I purchased? I will also be adding perlite and kitty litter clay? Any thoughts? I realize I should have posted this on the other video instead..sorry..
Do this reaction in a stainless steel container...NOT ALUMINUM!
not self heating...EXOTHERMIC REACTION
I used to cast a lot of metals and do porcelain work, the uses are endless, perfect for the diy person. Thanks for you work
Thank you, really enjoyed watching your cooking! I lost about 100ml volume in the process and as others the blue additive in cat little clumps up and floats on top. I strained the final product and added the water loss to make up to a 50% solution.
Nice video, what's the ml yield of this? I can pick up a gallon(3700ml) of sodium silicate for $25. Also I do industrial videography of foundries on my channel
I just made a batch of this today. I used a Metho burner camping stove. It didn't burn as hot as your butane burner. I just sat and stirred it constantly until I ran out of metho. It didn't bubble up while boiling like yours, but I ended up with the same consistency. While searching for Lye in my local hardware store, I was unable to find any drain cleaner that was more than 55% Sodium Hydroxide. I ended up Googling it and discovered that Caustic Soda is the same thing and I found that in the Plumbing section that was 100%.
+Shazbud Cool, that's interesting that they had both "drain cleaner" that was not pure as well as "caustic soda" that was.
Fantastic tutorial. I'm curious: what kind of temperatures are you able to achieve using your stainless steel trash can forge with the pearlite and water glass refractory set up? This question is related specifically to knife making. Is it really necessary to apply the "icing" to the pearlite, or could one skip this step? Thanks for sharing
Toxic vapors during the process? I am amazed at where looking at pizza oven builds can bring you here on UA-cam. ...lol.
At what point does the mixture become neutralized? I ask because many years ago waterglass was used as a preservative for fresh eggs. Eggs would be dipped in the solution, completely covered, set aside to dry then placed in nonrefrigerated storage.
Waterglass was also ( might still be ) used in the fireworks trade. I've used commercial waterglass and never had a problem even when bare skin came into contact with it.
I also am interested to understand in what dilution water glass can be used for preserving eggs.
Thanks for this - made up a batch after watching... didn't need to take notes (2,3,5 - 200 lye, 300 flower drying crystals (silica gel all crushed to fine powder) and 500ml water. Good pace of info, very informative and helpful... - Mark
If you soak wood in water glass for several weeks you get petrified wood. A US university team found that out in the 1980's while investigating petrified wood that has to have been produced fast. You can petrify some other things too but it needs dilution and more time.
if you paint wood with water glass, it becomes fire-resistant
This is a very very good presentation thank you a lot
looks interesting, can you help us in creation of glue using chemicals from Medical Adhesive Composion please

you sound like you were watching too much breaking bad :P
Using sodium silicate electrolyte to make Solid battery is very possible. Please Make one! teach people , Save the world from pollution! MAke even money!
Made my first batch. It works. He forgot to mention the Lye fumes. ;0P
Russell Schiwal Another youtuber mentioned that happening to him too, I think I added the lye so slowly I did not get that. All I got was steam that smelled like soap.
clkindred This still is an awesome thing. My plan is to make a mold on a kiln shelf that will let me cast a mirror blank for a homemade telescope.
Wow that's quite a project! A mirror blank? Glass or a metal?
Glass, 10 inch, I think. I'd like it bigger, but I can't get carried away.

(As spoken by Oliver Twist) Please, sir, may I have a video of this?
Not much is out there about Potassium silicate. Would you consider making a video on "double water glass" (an equal parts mixture of potassium silicate and sodium silicate)?
300g of silica gel is too much for 200g of sodium hydroxide. I did it and the sodium silicate left me after the process.
I would say that it is better to go almost the other way, 300g of sodium hydroxide and 200g of silica gel
Great video! Couple questions though.... where do you find the silica gel packets like you have? Other than in new clothes and shoes? And also, if you made the perlite concoction for the forge into bricks, could they be used for making an electric kiln? Are they durable and insulative enough? Can't wait to try this! I got an old helium tank this is happening to...
You can buy a four pound bag of silica gel at walmart for five bucks. It's sold as "mimi litter" cat litter. I have not tried making bricks, yet. I am experimenting with different recipes of diy refractory. I have found it is best to use the perlite as a secondary component to modify the properties of the refractory, not as a primary component as is can melt at high enough temps.
clkindred cool! thanks! Also thought about making your own lye using wood ashes and water... I think that makes lye as well... at least thats what tanners use to dehair their pelts... ill use your mixture you use for your forge and try to make some bricks... Ill let you know what I find out... good or bad... keep up the great videos man... thumbs up!

I want to no know if waterglass work's like resin?
I want to mix whit wood dust and other dusts like sand, and things like this.
I want to know if will harden and will be strong glue.
I want o to make musical instruments whit recicled wood dust
Thank you for share your recipe
☺️🙏🏾
Short answer is, kind of. It will be better at binding non absorbent particles like sand, rather than wood dust. When compared to resin or wood glue, waterglass will not work as well for those same purposes. I used this waterglass as a high temperature glue or cement to make things that can survive high heat, but it's more difficult to use than resin or other types of glue that would burn at high heat.
Made my first batch today in a big Pyrex container. Upon removing from heat the Pyrex shattered.
There are three types of Pyrex containers. 1. Mixing bowls that you cannot heat up; 2. Oven safe which can only be heated evenly and 3. stove top which is what is needed for this kind of project. The type is written on the bottom of the bowl and one should assume that if you don't see 'stove top safe' that you should not use it.
Pyrex isn't made from borosilicate like it used to be. It's either plain glass or tempered glass these last few decades. Plus they license out the name to other manufacturers.
Don't use Pyrex for anything other than measuring or mixing of food; that's all it was designed to do.
I want to thank you for this video on how to make it from everyday household stuff, I and my wife love to sit and make double batches for all the different foundries I need. I have plans for a tabletop gold and silver melting setup if I can get the walls thick enough and have a center hole that will hold a 2" crusable 2" high as well. All the things you can do with Water Glass, your trash can foundry, coffee can forge, and it can be added to sand to make bricks for a more portable setup. Great channel for do it yourselves.
Thanks for watching!

Great video! I just made a couple batches of this awesome stuff! I found silica gell at Michaels, its used for preservation of flowers, worked great! I learned the benefit of SLOWLY adding the gel, it boiled over hardcore, just with the chemical reaction, still worked just fine. I'll be lining my "mini" forge tomorrow. How long does it take to cure the perlite mix? Thanks man, I've been looking for a less expensive alternative to the cerablanket/plistix insulation/refractory for quite some time!
metalart0420 Depends on how wet the mixture is. As soon as the lining can hold its shape on its own, you can start slowly heating it.
I have a stainless chimney liner that I am installing to exhaust a high efficiency gasification wood boiler. My existing chimney would accept an ovalized 8" liner but not with the normal 1" insulation around it (made it too big and would not fit into the opening). I would like to pour an insulation around the liner and was wondering if a NaSIO2/Perlite mix could be made liquid enough to pour down a 15 foot opening? Would your mix work if I eliminated the plaster of paris and hand rammed it down each side of the liner? Will it eventually set up without the plaster of paris. The high efficiency boiler normally has an exhaust of 200 to 350 degrees max, but code says it must stand up to normal wood stove exhaust temperatures of up to 850 degrees. Any suggestions would be appreciated. Love your videos and ideas. Keep them coming.

Does anyone know if we can cast 3D objects with Sodium Silicate ( of this recipy ) as we do with epoxy resin ? Are there any additional directions to do so ? Is special concentration needed e.g. ?
Another question can we disolve lye in water in a pot, and separatlely the silica gel in another pot and then to mix the 2 solutions as to be A and B components similar to epoxic resins ? Are there any special advices to do so ? Analogies ?
And the last question: If sodium silicate is water soluble how can we make heat resistant adhesives for clay, porcelain, metals and other materials ? Do we need something more to avoid sodium silicate to be water soluble for the "adhesive" use ?
Thank you in advance.
Very good questions. I hope that you find the answers.

Herewith an alternate procedure that does not need external heat or stirring.
1. Prepare a suitable STAINLESS STEEL pot that has a lid. Insulate the pot e.g. fiberglass or a cloth towel. The pot may be glass or ceramic but absolutely NOT ALUMINUM.
2. Blend dry 300g silica gel cat liter with dry 200g lye in the pot. If you don't understand exothermic go to step six below - till you do.
3. Carefully, slowly add 500 to 600 ml distilled water. A 200F+ exothermic reaction is produced.
4. Install the lid and insulate it.
5. Wait 24hrs - done.
6. STOP
+jerry quigg Adding water to anhydrous NaOH can be dangerous. I would not risk it.
Sodium Silicate Supply stores sell Sodium Silicate Solution. Ceramic Supply stores sell it to use in reactivating old Slip. You carefully add it to the Ceramic clay mix because just a few drops is more than enough. to increase the viscosity (make it thinner).
Dangerous method. All it takes is for the container to be the wrong shape (tall and thin) or the ambient temperature to be too high (eg tropics) or a splash of water to be added too quickly or slowly, and you end up with caustic reagents flying into the eyes or onto the face of whoever used the method.
I should have added:
Step 0.0 - Don UR PPE. - Life is dangerous.
You can use sodium silicate to seal head gaskets! That’s the main ingredient in any head gasket sealer

Jabari yako mimi naitw vitalis nipo Tanzani nahitaji hio bidhaa utaweza kunitumia kidogo kwa njia posta
mine stayed gel like even after dousing with co2 (will harden if left to sit out all week, but still has a soft core)
unlike the video i mixed both dry ingredients, and then added water. after a violent reaction the water came up to boiling on it's own.
Not very safe. It is done in stages for a reason.
I thought I saw sodium silicate cheap enough to avoid having to do this!
I did double quantity. 400g of NaOh plus 1000ml H2O but could only dissolve 450g of silica gel. I think less water, maybe 800ml would allow it to boil earlier, speeding up the process. My batch took 40 mins and yield of 500ml strong water glass. I think I slightly over did it. Next time:-
800g NaOh, 900g silica gel, 1600ml H2O should make a litre of water glass.
Wow, very interesting simple process, but now I wonder, where do you get the plaster of paris used in the next video, how is it sold? and what is it (as names may vary)
+coline123456789 Sorry for the delay, plaster of Paris can be purchased from art and craft stores, as well as hardware stores. In arts and crafts it is used as a cheap casting material to make various things. In hardware stores it is sold mostly for drywall patching or seam sealing. It mostly goes by the name plaster of Paris wherever it is sold, but sometimes it is simply called plaster.
+clkindred thanks, the name paris confused me, plaster I do have, I've been collecting shoebox silica during this time!
+clkindred Finally tried the silicate reaction, interestingly, I got to the point of the drops freezing in the air before all the silica I added dissolved on the solution, how did you make yours to dissolve completely?
I have a magnetic stirrer-heater and balances to do all the steps.
Interesting, depending on a few factors, you may require more water to fully dissolve the silica gel. If you take your time, you loose a lot to steam, if the silica is added quickly, or is small particle size, the reaction heat can increase steam loss as well.
+clkindred I see, so it would be better in that case to increase the amount of water to dissolve everything and then take some time evaporating it again?
I was like "cool I can watch this and make my own for my forge". Then after watching I am like "oh hell no!" Little too risky for me
You can dissolve crushed glass in lye also.
Excellent informative presentation !
Would like to see warnings about using caustic soda/sodium hydroxide. This stuff will give you serious burns if you get it on your skin. [unless you are as ugly as me] wear a full face mask [at very least goggles] and elbow length gloves.

Sir pls sent rubber adhesive glue gume making video
All these posts are old but maybe some one will read and help, I am making, well trying to make water glass, using the same ingredients, the correct measurements, but it never thickens and cools down to a light brownish sludge, am I not heating enough? any help would stop me from pulling my hair out, thanx!
Sodium silicate glue is widely available in countries of previous USSR and it's dirt cheap. It's kinda surprising to see someone considering synthesizing a better option than buying it.
I made this with 100% lye distilled water an fresh step crystal cat liter. While making it it would seize on my stir stick but after six batches an pouring into one gallon container let it cool over night I checked it out an it does not seize on stick anymore. Is it good or bad Can I do something to make it correct without having to throw it away. Also it came out reddish purple? Any help would be helpful thnx. Larry
would commercially bought sodium silicate (40%) be suitable for this mixture? If so, how much would be needed to line a forge with 7" x 7" x 3" chamber. Thanks............
"this mixture" as in the lining I used in the forge video? 40% should be fine, however the water added will need to be less. I think I used 350ml of sodium silicate for the trashcan forge lining, and 350ml sodium silicate for the top coat cement. So in your case I think about a liter total should be enough, diluted with about 400ml of water.
Would flower drying silica gel work too?
Your recipe for a refractory binding agent has interested me. Have you considered using Potassium Silicate? From some of the articles I've read this may be even better to use in a refractory mix.
Jason O I have looked into it, potassium hydroxide is much more expensive than sodium hydroxide though. And in the end, it dose not matter which is used, because the silicate is cured to leave silicon dioxide.
I'll be honest I'm not a chemist, but I think the potassium silicate is sold as a fertilizer for mainly hydroponics. I saw some on Amazon for about 15$ albeit a quart size. Is this what you were speaking of?
www.amazon.com/Dyna-Gro-Pro-tekt-Tek-032-Silicon-Supplement/dp/B000E1VZHC/ref=sr_1_1?ie=UTF8&qid=1431225633&sr=8-1&keywords=potassium+silicate
Not exactly, I did look into that type of product as a source of potassium silicate, but it's pretty dilute. I was talking about the starting materials I used here to make sodium silicate. You could substitute potassium hydroxide in place of the drain cleaner (sodium hydroxide) to get potassium silicate, but the KOH is more than twice the cost as the NaOH, and harder to find.
Sounds about right. I did quick search for 100% potassium silicate, only to find the brand name "Barricade," is no longer being produced.
The NaOH is capable of turning the glass into sodium silicate, so a steel container is best.
I want to see a video of that. It seems very wrong to me, and I have used pyrex more than once WITHOUT issue.
@@dtrotteryt pyrex are boron not silicon based
I have an school engineering project where I need to build a Popsicle stick bridge using only homemade glue. Everything in my search up to this point has been questionable glues like jello and sugar water. I'm considering using this as my glue because it looks quite promising. For a Popsicle stick bridge supporting a load of up to 20 pounds or so (assuming the design aspect will hold it), do you think joints made with this glue would hold together? Also, can it be stored for later use (i.e. reheat cooled solidified mass)? Great video by the way.
How about "paste" or "hide glue"? People used these things for generations! Your application doesn't need to be refractory, it needs to be strong and adhere to wood. I bet you could buy some rawhide and cook it? Or some kind of starch or flour? You should be able to get something that will break the wood before the glue joint breaks.
@@leonardpearlman4017 It's been many years since high school, but I think we ended up using a milk or gelatin glue formula with casein and it was indeed stronger than the wood. Here was the test!

DOES IT REMAIN CAUSTIC AND HAZARDOUS TO THE SKIN AND EYES?
Good videos! I'm looking to try making my own gas forge sometime in the near future. Are there any particular brands of sodium silicate that you could recommend buying for those who can't or don't want to make it themselves?
richtus I don't think the brand is important, there was one brand that I was looking for that seemed like it should be available locally in hardware stores, but I could not find it. There were some other comments on this video where people found sodium silicate online, they provided links to the product.
I am here because i was about to buy an eye cream that vanishes wrinkles temporarily. and at the last moment thought I would look at the ingredients.
this was in the top two ingredients.
*I 'm not going to buy it :O*
CAT G.Blondecat Interesting, sodium silicate is in a few consumer products, but I have never heard it to be used on the body.
clkindred It's called my perfect eyes. you put a swipe under eyes and wrinkles vanish for a few hours.

hello very nice video i've seen videos on liquid glass used for cars having good hydrophobic properties will this one have the same ones ? and does it solidify with a special treatment ? thanks
Would silica sand (also SiO2) work for this reaction? Or is it necessary to be the silica found in the dessicant packs?
i am using Mimi litter for silica gel and i am using pure sodium hydroxide cant remember the brand off top my head but i made sure it was just lye nothing else in it. i got to be doing something wrong lol im like wth
I made sodium silicate last night. Followed directions closely...Outside in 38F degree cold, rainy, and moist air. (I was just inside my open garage door). I used a stainless steel bowl and electric hotplate. Now after cooling it's way too thick to pour. Thin it with distilled water?
steve snyder Yes, thin with water.
Can you use it to waterproof a concrete tank? Is it brushed, diluted?
Can I use it in a paint sprayer to coat my metal roof from the heat
Can I spray it on a white metal roof to keep my roof cool
Is the silica gel baked dry before it is measured out, or is that 300g with a random amount of water based on local humidity?
No baking, whatever water may be in it is not accounted for, I assume unless it's soaked the difference would be negligible. This reaction is pretty forgiving.
Thanks! I've been wondering about this for a long time. Do you know what kinds of temperature it can take before it starts to break down? I've been thinking about building a Rocket Mass Heater and looking for ways to make it last more than 2-3 heating seasons while it burns hot enough to eat the steel that is normally used to hold in the insulative masonry.
This stuff "cures" by decomposing back into silicon dioxide in a multi step process. So the heat tolerance of sand is what I compare it to.
would a corning hotplate heat enough to do this job so that I can use a stir bar??
Oh and is there any harmful vapors being produced here?
what's purpose of this gel
I think ill just make some after all.,, If I get my disability ill send you some glass where.
Or let me know if you want me to put it up on ebay for a dollar and you can puck up the shipping. I got so much it won't mater to me.
Cool! If you have any questions regarding the sodium silicate PM me.
The stainless steel bowl is better than borosilicate glass for your container because sodium hydroxide causes micro fractures in the glass over time with use. the stainless is safer.
I found Silica Gel at a hobby shop as a flower dehydration element. some blue crystals however it is still the right stuff and cheap I got 5bls for $15 US. Also on some hand made soap web sites my wife found 2bls tubes for only a few.
sodium silicate solutions and powder are inexpensive and are readily available from online pottery supply stores.
Can this be used on cars ?
No matter how slow or fast I add the materials together or the amount of heat I use, I get the same results. A layer of sodium hydroxide then a mess of silica, whole pellets and some gel.
I thought that sodium hydroxide was lye mixed with methanol . witch is 10 times as caustic as lye by itself
clkindred, Hi, hope you can advise, I have made several batches of Water Glass using the correct measurements and ingredients, the problem I'm having is the finished product does not harden properly by air drying, it takes ages to solidify but remains tacky to the touch. Also is there a catalyst you can add as a hardener to speed the curing process. Thanks :)
I collected a couple of pounds of dessicant packs but half of them were clay pellets instead of silica. Tried them in the lye anyway but they didn't break down. Still got a good turnout from the silica in the batch though.
Then I found some "crystal" cat litter and got 4 liters of water glass made from a single cannister :D
Which insulator would you recommend for 55 gallon drum based metal foundry, a perlite based insulator, fire bricks, fiberglass or a sand and plaster mixture?
its sorta like inorganic glycerine!!!
Sodium silicate was once very common in use around the farm, home and industry, now, I seldom see it!
I've been told that 'RU' type sodium silicate is the best for making core molds in foundry work, but all I can find for sale is type 'N'. I am nowhere near a chemist, but it seems that the difference between the two is basically concentration/thickness. What does this formulation yield? It seems like it would be even thicker than RU, but again- not a chemist.
Mike Barker This makes a 50% by weight concentration at the start. 500 grams of water, plus 500 grams total of reacted material, but when finished boiling the product until all silica gel is dissolved, it is more concentrated.
clkindred Thank you for the reply and info! If I am reading it right, RU is about 46% material, so I will try this with a little more water: 550ml.
