After cutting the tank, use a hammer to carve the nozzle of the crucible, this process is very easy to follow. The final step will require you to drill holes in the tank and insert nuts and bolts.

I found this steel crucible while looking out for the best, and I must say, the creator did a great job putting this steel crucible together. The making process starts off with using 50-millimeter square steel tubing and a 16-millimeter steel plate for the crucible. You can make yours off scrap steel in your home.

If you are using the same steel as the creator, you will need to cut out the base of the crucible from the steel plate and get-ready the square steel tubing. Next up, you need to weld the steel plate base and steel tubing together. Building the handle comes next, however, this process is quite easy.

This crucible is only ideal for melting aluminium, anything above 760 degrees would melt the crucible.

You also need to know that the crucible you build will not last forever, after a couple of uses, you might need to make a new one for yourself, that shouldn’t be a problem because most of the crucibles cost $0 to make.
