Cool demo. Also better to make mouth of cavity shorter and depth of cavity deeper. Helps in melting metal faster, and not depleting entire oxy-acetylene cylinder.
That's usually the case.. its a TERRIBLE media for crucible. Physically, chemically contams your melted metal. It's very very far from ideal. There are equally cheap and equally easy ways to make crucibles that won't cause the same issues
That's awesome my guy I will definitely remember this video when I start pouring. Everytime i watch one of these videos I learn something I didn't know thanks for the info bro 🍻👍🍻👍🍻
@@4ninesfinesilver315 your welcome thank you for making these videos I'm gonna need all this info soon now I wont have to go around askin people a million questions lol🤣🤣🤣
Hello 4nines Fine Silver sorry I’ve been missing your videos. Great instructional video my friend I appreciate you sharing. It’s so helpful I’m about to start my new pouring adventure and very excited to be doing it. It turned out great thanks for sharing. That skull is so detailed way to go I’m not a big fan of the skulls but that one is sweet . You are awesome my friend. I hope you have a great week. Keep pouring Best wishes
I wish we could see the chat in replay. I had asked if you had used this much yet, before posting the video and how well it's held up verses the plaster of paris ones? The same? Better? We have some posts to set when the ground thaws here this spring and we could make up some of these to use if they hold up well!
Playing with molten metal is no joke. Because your crucible is not hot at the bottom doesn't make it safe to be handling it without a glove. It only takes one screw up and that metal will become part of you. I hope it never happens to you but if it does I hope you man up and warn everybody about how dangerous carelessness truly is. What a nightmare waiting to happen.
Hi, as I watched this the thought that there may be a safety concern crossed my mind. First, kudos on experimenting. Many USA versions of prepared cement have small rock(s) in it. There is a potential for these rocks to explode. Thus, it may be that one is better off mixing their cement from scratch using "fines" (sand) and powdered cement only.
Yes I agree with you you are better off to use cement alone with no sand or anything else in it I am just preparing to make a new video on that very subject I have had never had one explode as yet but they do tend to crack after a while👍
If you get Portland Cement it does not have rocks and other aggregate mixed into it, concrete on the other hand does have those rocks. To be sure to get a cement not a concrete mix
I think you would have to adjust the shape of them but I think it would stand up quite well because I’m not using any sand there is nothing there to breakdown🤠💛😎👍
These are interesting, but I am not sure how long they would hold up in a traditional gas fired furnace. If they had any moisture content they would probably end up cracking and you wouldn't want that. Usually most refractory cements are designed for the immense heat of the furnace. You are probably looking at 24-2500 degrees when you pull the crucible out, at least for the outside wall temp. It would be something to test a few time b4 using any metal in it. Did you bake them any in a oven or just sunshine? Just looking out here, you really dont want a steam explosion or a crucible full of molten metal hitting any part of you.
With as little as I know, I would recommend adding a bake off to the initial air dry. I'd even go so far as to bake it at 250F for a couple of hours in a conventional oven, to prevent a catastrophic failure, in an effort to drive all of the residual moisture out of the piece. Also, use less material. You do not want an internal steam explosion. It could ruin your kiln, or severely injure you.
@@silverunicorn2645 you are exactly correct. I'm more than guessing it wouldn't hold up in a regular furnace. Seems to work pretty good for the acetalene torch. I don't think I would risk using anything other than clay/graphite or ceramic. If you could get your own clay and graphite and make that way, would be better.
Awesome that is great news to hear the extra Watch time and the thumbs up wouldn’t hurt that’s for sure😂😂if I can help in anyway don’t hesitate to email me with your questions .🤠💛😎👍
Amazing proof of concept video I just have one question. Can this crucible withstand temperatures to melt steel or iron? Thanks again for the lecturio!
The honest answer is probably no . if you vibrated the mix very well and made sure all the oxygen bubbles were out. It may work but you would be much better off to use a graphite Crucible in a furnace. 🤠👍
@@4ninesfinesilver315 thank you, sorry for. All the questions, the graphite you referring to is that black fine powder that they use for dry lubrication also?
I like that your T-2 is like my One Eyed Willie on my table top... Table mascot! Really fascinating stuff man... Did you just learn all this stuff by trial and error? Found this video so interesting! Way cool! Crucible works like a charm! Really awesome skull bro! Great video!
Yes mate I needed a new Crucible and most of the suppliers were overseas and I didn’t want to have to wait two or three months for the delivery so I thought I better start making my own and each time I make a new one I improve on it my first Crucible video has received over 7000 views so far and so I thought I would keep doing them until my channel started to grow🤠💛😎👍
Hey mate very good vid I just wanna know would I be able to melt my alluvial gold down in this and how much do you think would be the limit? Sorry for asking im just not sure. Thanks in advance.
Thanks for your question. The short answer is yes it would work, but you would be better to spend a little bit of money on a ceramic Crucible because gold is very expensive and I would hate to see you waste any🤠👍
I see the glaze and bowl shape was immediately damaged after that one use. Would a patch up on damage and reglaze make this reusable or would it best to recycle the old ones into a new one?
You can definitely patch up the glaze I’ve had one of these crucibles last for months with constant use, although if you were going to melt metal on a regular basis, you would be better off with a prefabbed Crucible. They are not very expensive. I also have a video on subject ua-cam.com/video/OMyssKCzN48/v-deo.html 🤠👍
Very cool use of cement and lime. Normally when I buy cement and lime it's because I'm trying to disappear a body.
Thanks mate I really appreciate you turning up to the premier and leaving a great comment 🤠😎💛👍
🤣🤣😭👍
I think the other trick to hiding one is to not talk about it but that might just be my rule. *shrugs * lol
@@silverkeys To each their own!
@@Shawn47 Here we have wolves and bears and more so that helps to dispose of waste. Lime for the loo. LOL
You have done our community a great service. Thank you sir!

Excellent video. I never knew it could be so cheap to make a crucible. Thanks for the info 4nines Fine! 😎 👍🏽 🤠
Thanks very much mate I really appreciate you turning up to the premier and leaving a awesome comment 🤠💛😎👍
I love that you don't mind sharing your knowledge! Thank you sir.
You are very welcome and well appreciated thank you so much🤠💛😎👍
Super reasonable crucible! We've made two--will make more when our weather warms up!
Very cool. I like the idea of a homemade crucible
It’s a lot quicker than waiting for them to come from overseas that’s for sure 🤠💛😎👍
Cool demo. Also better to make mouth of cavity shorter and depth of cavity deeper. Helps in melting metal faster, and not depleting entire oxy-acetylene cylinder.
Great idea 4Nines Fine Silver 🐙👍
I like very much the sound of the hot pour template on water
The skull looks awesome too😎🥇👍
Yeah a lot of people like the sound of the quench when the red hot metal touches the water🤠💛😎👍
Great video and lots to learn! I will look to pouring come fall/winter this year!
Thanks mate I really appreciate your comment and support my friend 🤠😎💛👍
I'm amazed that the cement did not blow up! The times I have tried to use cement , plasters , lime to melt in they were explosive grenades.

I am extremely curious about how these could hold up in a gas furnace. This is something I will have to experiment with
I think you would have to adjust the shape of them but I think it would stand up quite well because I’m not using any sand there is nothing there to breakdown🤠💛😎👍
For the price you have nothing to lose to try 💛😎👍

Amazing proof of concept video I just have one question. Can this crucible withstand temperatures to melt steel or iron? Thanks again for the lecturio!
Thank you for your question Alex but I would probably say no. you would be better off to get a graphite Crucible for steel. 🤠👍
Can you put this kind of crucible in a furnature, resist 1200 C? Thank you, is good the video
Exactly what I hoped for. Do you have any vids on crucibles that absorb x y or z.(being metals)?
Hey Shane thank for your comment . Not sure what you are asking, but I will be doing another crucible video soon.🤠😎🤩👍
A cupel?
Beware if concrete has any moisture in it ,it will explode like a river rock under high heat.
Yes Mike you are right. You must let it dry out completely 🤠👍

Hello my friend that is a special mix of green sand made with the finest silica sand on earth thank you for your comment😎👍
So can you use mapp gas to melt the metals in crusable as well
Yes it just takes a little while🤩👍
Can you use these in an electric oven??
Thank you for your question Bryant. But you would be better off to use a graphite Crucible in that situation🤠👍
👍👍✌
Thank you I really appreciate your 👍👍✌️. 🤠💛😎👍
You can use dirt and stuff for molds too right
Not sure about using dirt I haven't tried it before. I normally use sand 😎👍
What is grey cement? Is it normal building cement?
Yes just normal building cement 😎👍
thank you!
Thank you 🤠👍
What is the mixture?
50/50 lime/cement
What is garden lime ? Is it calcium carbonate?
Is the lime means CaSo4.2H2o ???
