So I'm wanting to build a small metal foundry to melt down aluminum cans, but I want to expand to shit like iron and steel eventually so I can start getting into forging.
What would be an ideal material to use as a resilient crucible for the tougher metals?

God damn it, use fucking google, you have the fucking library of the world at your fingertips and all you can manage is begging for someone to hold your hand. With your level of motivation you aren't going to get anywhere with this shit anyway. Fuck I hate all the dipshits on YouTube giving stupid people these vapid ideas... You are going to burn your house down and I won't feel at all bad about it.

do you want to make your own? If not just go to some website that sells them and find one that suits your purpose.
As for melting steel. Well it would be incredibly difficult on the hobby level

This man. I have no interest in making a Foundry, but I actually read a book on how to do it once. It was called 'The Cruciple Furnace'. You have some options but it can get pretty expensive depending on what metals youre working with. There is a reason people write books on the topic.
High temp refractory cement or mortar up to 3000f. You can get it lots of places. Get a thick wall of it in a crucible. For blacksmithing you dont need that much temp ability.

Or just look up a bloom foundry, dig a hole and use a bunch of mud like a pre-industrialized chimpanzee.

You'd have to buy a specialty made one to handle steel. But my smelter is literally made of chicken wire and dirt piled up on a break drum. My crucible is a 2"x2" piece of tubing with 1/4" thick walls with the bottom welded up. I use it for casting copper/brass/zinc.
Melting copper/brass/lead/aluminum is easy as shit. You can get the required temperatures just by blowing a pipe into some charcoal.

I've been wanting to make one of these as well. You could use a 3d printer to make molds for casting to aluminum, or Styrofoam. You could also make blocks that you could turn on a lathe or mill
>>1003226
make the smelter from concrete or mud
let it dry and use a waste oil burner
should work a couple of times.
>But you need a good ceramic or graphit crucible

Go here and learn.
Use cheap stuff and learn how to cast aluminium.
With my set up ive developed over many years, I can melt cast iron. But I dont bother 99% of the time. The radiant heat is brutal, the safety gear is hot and stuffy, the fuel consumption is crazy
Cast aluminium is perfectly fine for most stuff you want to make

because aluminum can killed my mother and raped my father

Pics or it didn't happen. I'm hoping it happened.

plaster and sand will get you started.
i made one out of old bricks too.
forging steel and iron isn't a problem, since you're not trying to actually melt it, you don't need a crucible or even a lid. just heat it up to the color you want and beat on it.
and as others said, try not to burn your house down.

ceramic. ceramic is best.

Hey Grant, is this where you get your ideas?

Graphite crucible would be best. I assume they are kinda brittle tho.
Here's another advice, ever heard of induction heating? ZVS?
