I know that in order to smelt stuff, you need to heat it until it melts and then pour it into a form. But that oven and that form always need to have a higher melting point, right? So how do we create the oven at the top? How do we create stuff when nothing with a higher melting point exists to make an oven out of it?
Edit: I think I understand now, thank you again to the kind people in the replies who explained it to me 🙂

The short answer is you make the crucible and oven out of higher melting point materials. These are usually ceramic. Ceramics generally have much higher melting points than metals. They also don’t need to be melted in order to be formed, which prevents the “well then how do you smelt the crucible” problem.
