- I recently glued 2 fire bricks together with some high temp glue i made
and was amazed at how strong it is .

See my water glass videos to learn how to make the potassium silicate binder
@@NOBOX7 water glass aluminum oxide and carbide sand makes a nice refractory for crucibles.
When water glass (sodium silicate) is mixed with aluminum oxide (Al₂O₃) and fired at high temperatures, a composite material is formed, primarily consisting of nepheline, a mineral that contains both sodium and aluminum silicates. This reaction occurs as the sodium silicate interacts with alumina during the firing process, typically at temperatures exceeding 700°C. The resulting material exhibits enhanced fireproof properties and thermal insulation characteristics due to the formation of a heat-insulating layer from water vapor released during dehydration of water glass.The addition of alumina not only improves the mechanical strength and durability of the composite but also stabilizes the melt, preventing crystallization and ensuring a more glass-like structure upon cooling. This composite is particularly useful in applications requiring high-temperature resistance and insulation, making it suitable for use in fireproofing materials and thermal barriers in various industrial applications.
I think my commenters make this channel better than it actually is and i thank you for that . You can learn so much from a scholarly individual or the specialist like yourself .
I've been making and experimenting a lot with water glass myself. Mixing it with plaster will instantly cure it and the material is much tougher than normal. Letting it soak in crushed bentonite will create a paste that can be painted onto an object and will resist deformation under heat.
By the way a Non Newtonian fluid is the umbrella term, but you can call the substance a dilatant fluid or pseudoplastic fluid to be more specific.
Hey mate, non Newtonian fluid is the word you were looking for. Good info in this video thanks. I'm currently building a foundry using potassium silicate in my DIY refractory concrete, got the idea from your previous videos.
Note - I will eventually get around to uploading a video about it, but if you want to make your own mix please do not use only Portland cement, it will explode, use 1:1 Portland and lime mortar. The rest of the mix is up to you, but I think I have a good mix going with accessible materials.
Right on brother , i new there was a word for it .
@@NOBOX7No worries 👍 That additional note wasn't for you, I know you know that, I just noticed on Google that the first result for DIY refractory concrete doesn't use lime, so wanted to warn people reading my comment about that. I managed to get my hands on cheap pure CaO that is used in pond purification apparently, but I guess people could use lime plaster, though I'm not sure what the ratio of lime to aggregate is in that.
Guys when i say i cant get any thing to stick on metal im referring to the cool down cycle of red hot metal . It will stick to metal very well and sticks to red hot steel just fine but im trying to coat stainless
Sorry about the volume Its a new software
This channel never disappoints. I have one of your burners, I think "Godzilla" or something like that. It is, RIDICULOUS. If I wanted to melt the sun and cast it into something else, it would do that.
Thanks for sharing your experience and knowledge. I love this video ❤
I've been doing parkerizing metals, it forms manganese phosphate crystal web around ferrous metals, idk the adhesion strength of those crystals to the metal, but I know that it was widely used since ww2 in famous weapons like the garand and the 1911 pistol to prevent rust.
Now is my go-to choice to rust prevention, better than bluing, it holds oil like a champ between the crystals and protects from wear and is easy and quick to apply, maybe it can be useful to glue steels with your formula.
I wonder if it works on stainless , Great input though . That would make a good crystal base for adhesions
Try making black oxide solution. Its more consistent than parkerizing
@@preciousplasticph its hot caustic bluing with potassium nitrate?
very interesting and thanks for sharing. id like to see it tested while at temperature
Damn... i love this channel! Always learn something new.
As i said in ur last comment.... Now add some KOH to it (pre disolved in distilled water but as little water as u can use it) now get yourself some fly ash or go to a crafts store amd buy a block of white clay. Heat the clay untill you cant heat no more then bust that shit up blend it up as fine as you possabley can till it want to blow around like the ash from a burned kleenex use like 75% weight or something in that range.
Throw it all into a pot and use a high speed drill (much faster than a drill can spin the key is high shear)
glue fire bricks.....that can be business, man. I can imagine making a portable aluminum furnace powered by oxy torch or whatever burner that can set up quick and cheap, smell like money, my friend!
Good discovery, thanks
When are u gonna make crucibles for melting cast iron or other metals your experimentation is beyond expectations you are a over achiever keep on trucking
I wonder if the material was to be cured under a vacuum and made it more durable…🤔
Boron Nitride might be interesting in the formulation....
It'd be cool to see if this is a better rigidizer than waterglass alone.
Those bricks could be corderite or magnesium aluminium silicate. Kiln shelves are made of this.
The potassium silicate preparation in question, for anyone who had trouble seeing the label on the bottle:
45% H20 331mL
32% SiO2 240g
21% KOH 160g
I don't know what the last 2% was.
is potassium silicate water glass the same water glass you made or what is it made of
I've seen diy firebrick made with waterglass soften at higher temperatures. Does this material do the same or is it resistant to softening?
will it give an advantage and paint my forge with it inside
It's a non-newtonian fluid.
