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.

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.

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.

So Interesting !

[@acdbrn2000]

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.

[@bobbrawley2612]

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

[@daphneraven6745]

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.

[@markhonea2461]

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?

[@daphneraven6745]

⁠@@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.

[@justinw1765]

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.

What is the difference between Sodium Silicate 40% (Water Glass for pottery - $19.99/gallon) and creating this kitty litter stuff?

Just curious to the cheapest way because the ready made gallon jug(40%) seems a lot easier.

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.

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.

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.

[@davidlacziko1516]

You are making only water glass, but not the refractory mix itself. What ingredients and ratios do you use?

[@darrellpidgeon6440]

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.

[@Struthio_Camelus]

Wood ash produces potassium hydroxide (KOH), not sodium hydroxide (NaOH). As Sergey Plisov said: SiO2+NaOH = NaHSiO3

[@DavidJohnson-tx3wj]

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.

[@diyshoptools9157]

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)

Or moldings to include chimneys . Rocket stove heat rises molten metal vessels. Water glass combined with the aggregate is an insulator so that generated heat remain and intensifies within the furnace fire chambers

[@JohnGuest45]

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

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

Never react NaOH in an aluminium vessel, because it creates hydrogen gas. OH THE HUMANITY!!!!

[@bjohnson2143]

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?

48 clicked dislike because they poured too fast and created A LOT of heat :P

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.

[@bobbrawley2612]

@@HoneyDoCarpenter there are tons of videos on the crystal kitty litter formula . I guess he is talking about one of the other guys videos

[@ClownWhisper]

@@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
