I loved this video. Could you make more about the crucibles? An assessment of how long it lasted, or compare it with a purchased graphite and refractory one? Or make several and see if they all come out the same. Or just anything really. I've been looking all over for good crucible videos, especially for DIY crucibles for cast iron and just not finding a whole lot THANKS!!
Thanks for the positive comment, I will try to find the answer to your questions, I will be testing the crucibles, it's just a matter of time. The previous crucibles that I made without the use of a press withstood a dozen or so castings and nothing happened to them, I just wanted a larger crucible because the furnace can melt more and I want to use it, just watch my channel, because I will continue the topic of crucibles and maybe you will find answers to your questions in my videos
@@warlof1 Very cool btw! Graphite is a good choice. Halfnium carbide powder of you can find it would work well with it's extreme melting temp. Question? Why did you use 25% graphite and not more? Also, as you seem to already know I suspect using the min amount of pure water with have the highest psi this hardness this heat Resistance.
@@l0I0I0I0 I looked through various thematic forums and the experiences of others in the creation of crucibles that this proportion is appropriate, graphite simply combines well with chamotte mortar in these proportions. But when I find some free time, I will also take care of trials with more graphite, and we'll see what happens :)
Vibrating the mold while compressing by tapping with a 2 lb piece of wood or equivalent rubber hammer, would help the crucible mass particles compress together better. You'll find you get more movement on the hydraulic press after tapping the mold.

Dziękuję za pozytywny komentarz. Staram się zawsze wykorzystać te materiały które akurat mam pod ręką, segreguję złom i odkładam to co mogę wykorzystać w przyszłości, tak jak materiały użyte w tym filmiku zbierałem jakiś czas a nie kupiłem. Pozdrawiam ;)
Nice job! That inner mold form looks like a lot of work. What if you used a stainless steel martini shaker for the inner form and poured it solid full of aluminum? Just thinking. What exactly was the change that you made to the outer mold? Was it just shortening the limiters and adding the handles? I bet you could use a flex-hone to polish the inside of the outer mold and make it ever so slightly conical. Keep up the good work.
The inner part of the mold can be made of aluminum, I just made it of steel because it is easy to convert something made of steel, for aluminum I would need a different type of welding machine if there was a need for a conversion. Yes, the change in the outer part of the mold consisted in shortening the stops and adding handles, if I made a slightly conical shape in the outer form you are right, also the crucible would be easier to pull out of the mold, without trying I would not know what could be improved, I will continue the project.
Yes, it will withstand copper melting, in another video I show copper melting in a smaller crucible that has exactly the same composition as this one. th-cam.com/video/3-J-v11aI6A/w-d-xo.html
What materials the crucible consists of I show in this video th-cam.com/video/CSiR-ms2X7Q/w-d-xo.html I just did not want to show the same as I showed before, what it consists of, I try to convey specific information without boring. Thank you for your comment and best regards.
I would have to test this crucible to see if it can withstand iron melting to answer that, theoretically it should withstand because it consists of materials that are resistant to a temperature of 1900 ° C. In my opinion, it pays off, because the costs incurred to make the crucible are small and you can learn a lot from even a failed attempt.
@@jorgep.2033 The composition of the mixture is 1/4 of powdered graphite and 3/4 of fireclay mortar and a small addition of water to combine the mixture. In this video I show the lineup th-cam.com/video/CSiR-ms2X7Q/w-d-xo.html

Hi, when it comes to the specific moment when it shows the internal dimension of the pipe at 0:37 seconds, it is exactly 98mm, best regards and thank you for your comment.
Another useless comment from the arm chair foundry guys. Clearly you've not done much of this kind of stuff. Even the so-called inexpensive, yet rather well made, crucibles from India are not inexpensive in the long run. If you cast a lot, you'll go through lots of crucibles. If you cast different metals and especially alloys (and you understand what you are doing), you will keep different crucibles specifically for those base metals and alloys. It all adds up rapidly. Using the materials and methods this video's author explains will reduce your costs *substantially*
This video may help you get some ideas. Hopefully you reply back to this comment if you make a video with something new taken from it. I want to make one someday, need to build a forge so I can melt some gold (not much 😂). Thanks to all this videos and ideas, now I know how to make a small rectangular one to make a small ingot. Good luck. m.th-cam.com/video/UIm7SbyXJeM/w-d-xo.html
Thanks for commenting and showing this video. I will try to recreate the crucibles they make there because I can see the consistency of the mass from which they make the crucibles is different and I want to compare it with mine, I am curious myself which one will be better and I will record a video about it. Regards ;)
Amazon and Ebay are woke garbage, that's why. Woke garbage and highway robbery. Who even likes online shopping? Don't get me started on PayPal. Besides, I saw a foreign TH-camr make fireclay after boiling terracotta in muriatic acid.
I'm sure he did all this work and went to the trouble to make this video and respond here consistently to comments - including repeating what he made it out of at least 4 times, with a link to a previous video on how to combine those materials - all that just so he could get your shitty comment. Thoughtful reply, pal. Maybe you should post a video on how you make crucibles out of goat and yak dung?
The amount of tools this man has on hand is astounding.
ah, well, that's relative. :)
I loved this video.

@@warlof1 Chamotte mortars. I WOULD LOVE to make a HUGE crucible! Special application.
@@warlof1 Is there an Chamotte mortar, ultra high temp you can recommend?

Thank you for your valuable tips. Regards
Orbital sander much better. Or a saw
I like your style. Thanks for posting.
Apa bahan untuk pembuatan crusibelel nya bosss q
Really nice work. I read that you added graphite powder, but what kind of concrete/cement did you use? :)
The cement you are asking about is fireclay mortar, i.e. powdered fireclay brick with the addition of Portland cement.
I found this stuff called heat stop at a masonry supply yard that works pretty well
@@lewisgiles8855 That was the point, the trade name for this product may be different from country to country, but the composition is the same.
hi can you cast steel in it, have you tried it?
I have not poured steel in such a crucible, I will have the opportunity to try soon.
what was the morter like stuff you used?

I'm gonna try this. Is it strong enough for copper melting?
Yes, it will withstand copper melting, in another video I show copper melting in a smaller crucible that has exactly the same composition as this one.
th-cam.com/video/3-J-v11aI6A/w-d-xo.html
As long as you don't use terracotta, you'll be fine. Red clay will vitrify.
Composition? You show yourself mixing a bunch of mud, did you dig it up out of your garden? Missing a step here...
What materials the crucible consists of I show in this video th-cam.com/video/CSiR-ms2X7Q/w-d-xo.html

I saw another TH-camr make fireclay after boiling terracotta in muriatic acid. Clay went from orange or brown to gray.
Do you think this is strong enough for iron casting? And overall, do you think the process is worth it?

What is you mix ratios for the Crucible.
The proportions are one-fourth of graphite and three-fourths of fireclay mortar
Nice work!
What kind of mixture do you use?
The mixture for the crucible is: 3/4 fireclay mortar and 1/4 graphite dust and a little water to combine it, the consistency is to resemble wet sand.
Use enough water to get fireclay and carbon clumpy enough.
He shows us the caliper, but before you can see what it says, he yanks it away?

Good job.. Bro
Din ce material e creuzetul?
No to fajnie!
BRILLIANT 👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼
?? what is it made of??
ОК!!!! Попробуй в следующий раз, добавить туда порошок графита примерно 25%
To this mass, I added graphite powder, from which I made a crucible
👍👍
you get a few kg of molten metal breaking out of that and you will just buy one

I think I’ll stick with the factory lol.
Kaise milega aur kitne mein paise
easyer to just buy one
That's not the point. DUH
Ok so you saying its cheaper to buy one than make yourself 😂
This video may help you get some ideas. Hopefully you reply back to this comment if you make a video with something new taken from it.

I wasn’t terribly impressed. I’ve seen better crucibles being made with not so much welding and forming the dye. Just saying…
Useless and frankly stupid comment. Not just saying ...
You are working form long time but not gaining subscribers...
why bother, just order one on amazon or ebay, way less work and probably same shitty quality.
