A couple Thoughts….for the middle mold instead using something that can be taken out in pieces like say metal rods surrounded by a plastic bottle and for the outside Some thing thicker Wald that can be cut in half and then just clamped together to be reusable over and over
I have already done what you are talking about, I invite you to watch this video of how I did it, th-cam.com/video/7x3zu4wFusY/w-d-xo.html what do you think about it? :)
DIY isn't necessarily cheaper if you think about it. People that think it is are people that do not value their time. If a person correlates their time to roughly what they make per hour at their job, and they calculate the time spent on DIY projects versus just buying the ready-made, they will find that their time far exceeded the cost. Yes it might be cheaper by the dollar for the materials but if you include your time you actually short yourself. That is time you could have been doing something productive making the money that you have lost in this project that you could have just bought. The only time DIY is feasible is when your time in terms of per hour monetary gains does not exceed the cost of the original product; or if you want something custom that can't be bought or for specific custom purposes. I'm sure it took him quite a few hours to do this. The cost of this crucible in materials would be about five bucks. The cost of premade this size would be about 40 bucks. So if he calculates his time on top of it I'm sure he wasted far more than $40 worth of his time to build something he could have just bought and the purchased product would almost definitely be better. I am only here because diyers sometimes have ideas that are beneficial or can be an upgrade to another product, but based on his use of materials, and the time taken, this is not one of them.
On the other hand, learning to simplify the process to make crucibles in 30 minutes is priceless. Sure, buy the $40 crucible for a couple of melts, that's great. But I need a bunch of large crucibles, and $200 per crucible isn't something to sneeze at, especially when they may not last past 20 melts. In this case, yeah, knowledge is priceless.
Here you are, there is this product in my country available at this link www.leroymerlin.pl/materialy-budowlane/zaprawy-i-tynki/zaprawy-murarskie/zaprawa-szamotowa-zsz1-iii-3-5-kg,p480877,l358.html I will not send the photos because at this point I do not need to buy fireclay mortar because I have a large supply of it. I hope I helped. Regards ;)
Good video but I really wish it didn't have background music. I don't know what possesses everybody on TH-cam to add background noise. No tutorial or how-to video should EVER have a soundtrack overlay.
I believe it acts as a reducing component in a chemical reaction with the alumina in the mortar causing the alumina to turn into a simpler aluminium oxide once burned in. Also causing bubbles of carbon dioxide to form giving it better insulating properties, however, of that i am not sure.
Lol, mixer got away from your there, flung out half your mix. Refractory mortar is pretty expensive, but i bet still less than buying pre-made crucibles. I’m def gonna give this a try, thanks!
The cost of materials in dollar terms is $ 5, and buying a ready-made crucible of this size is $ 40, I invite you to watch me make a crucible twice as large. th-cam.com/video/7x3zu4wFusY/w-d-xo.html
What is another name or actual chemical name for chamotte? This product is not available here by that name. I have locally a large ceramic/clay supply house but they don't know what chamotte is. They sell 15 kinds of grog and 10 kinds of fire clay but they are all sold under a trade name.
Fireclay mortar is a powdered fireclay brick with the addition of Portland cement and is used to connect fireclay bricks, and fireclay bricks are used to build a hearth in furnaces, fireplaces, bread ovens, etc. this fireclay brick would have to be crushed to granulate sand, add Portland cement if you find it and do the rest as I did in the film. Let me know what the result was, best regards;)
Chamotte is mainly aluminium trioxide and silicon dioxide with some other stuff mixed in there like metal oxides. If you wanna get some of that for cheap or for nothing but a bit of work, collect a bunch of old clay pots and grind them into powder and you have chamotte.
Jeśli chodzi o zużycie tygla to jedyne co to się wypalają i powstają ubytki w powierzchni tygla, ale to naprawdę trzeba dużo przetapiać by tygiel wymagał napraw, a te ubytki, uzupełnia się taką samą masą z której są zrobione i potem przy kolejnym przetopie się wszystko łączy w całość, więc jeżeli się nie narazi tygla na wilgoć albo ekstremalne skoki temperatur to tygiel długo posłuży.
Exactly as Dawid H wrote above, if I left the outer metal part of the mold, it would burn at this temperature, and the metal remnants would contaminate my foundry furnace.

If you cannot get graphite dust, then you can use charcoal, which you need to pulverize, but it will be of poor quality as you would have to grind it down to 45 μm, which is very difficult to do at home. Indeed, I meant easily available ingredients, not free ingredients. I’m sorry for the trouble.
@@warlof1 I knew you meant easily available..english is a useful language but there are too many words meaning almost the same thingYou could easily pulverise charcoal with a lightweight drill powered chain mill (same idea as the gold prospectors use but DIY)
I know this, but the crucibles you can buy have a different composition. I would like to compare the purchased crucibles with those I made myself. There will be a video about this in the future.
To answer this question, I need to order ready-made crucibles and compare them with my crucibles, I haven't done it yet due to lack of time. It may turn out that mine will be better for one metal and those from the store will be better for another metal, it is certainly easier to buy than to make a crucible yourself. Regards@@strikerj4810
@@Bourne246 sure thing. He is from a starnge land where angle grinders, plaster in retail packaging, freaking bags of graphite, cameras, computers, internet access but an inexpensive crucible is just a bridge too far......
taking a grinder to an aerosol can is always a great idea.
Just ask my buddy...he can't hear you...or see you...or shake your hand...but you can ask.
Probably depressurized seeing as it didn't explode, so yeah it was a fine idea.
Great video!
Really good video thx!! And the music is Epic!!
Thank you for sharing!
Nice job ..earnt you a subscription

When casting silver I know you can use soot as a mold release agent. It might work for this too.
Thanks for your comment and thanks for giving me an idea with this soot.
Nice tutorial subbed…….. And now I know that my crucible mold can double as a floor jack extension also😂😂✌️
Please provide the website or store name and address of where you got the chamotte and a full picture of the chamotte bag.

Hi. What do the graphite do? What if only use mortar?
graphite a good thermal conductor, it will help prevent uneven heating and cracking.
I believe it acts as a reducing component in a chemical reaction with the alumina in the mortar causing the alumina to turn into a simpler aluminium oxide once burned in. Also causing bubbles of carbon dioxide to form giving it better insulating properties, however, of that i am not sure.

Freely Steal-y from your company or taxpayer? Or freely bought at the store?
I feel like we were making crack or something. But this was a useful video thanks
Crack is easier to make...so I hear...

Extra film, taniej samemu zrobić niż płacić na allegro. Jaka jest wytrzymałość takiego tygla?

Fucking Finally, I find a video on how the F crucibles are made of, ty sir~
I cant find the graphite for sale.
Look for "dry graphite grease" in the store or replace it with ground charcoal, but the effect will certainly be worse than obtaining graphite dust.
Get a bunch of pencils.
Forgive my ignorance, but why can't you leave the metal on? Why did you cut it off ?
Thank you for video sir
At what point?
@@warlof1 Myślę, że chodziło Mu o formę zewnętrzną tygla :) Pozdrowienia i gratulacje za dobry materiał!
Because the metal will burn and melt into the foundry. Hence the need for graphite crucibles in casting.
oh ok
Exactly as Dawid H wrote above, if I left the outer metal part of the mold, it would burn at this temperature, and the metal remnants would contaminate my foundry furnace.
How are those freely available materials?
Commonly available material is simply material available in most DIY stores
@@warlof1 Thanks, in my country you would have to visit countless hardware, gardening and who knows what other kinds of stores to try and find those.

Just a tad dry when u broke it with hand it wasn't a clean break

BY FAR THE MOST PAINFUL VIDEO I'VE WATCHED ON TH-cam 🤬🤡
What are you talking about??????
why?
because a professionally-made crucible would cost about $17USD & be FAR less porous, and have a much better shape & flatter top surface.
Maybe crucibles are not readily available from where he is..
@@Bourne246 sure thing. He is from a starnge land where angle grinders, plaster in retail packaging, freaking bags of graphite, cameras, computers, internet access but an inexpensive crucible is just a bridge too far......
Damn there's some dodgy stuff going on in this....
What is dodgy about it?🤦♂️
$17 crucibles on amazon are what's dodgy. Imagine one breaking while full of 2100'f copper.
