induction "furnace" from microwave transformer?

Hey guys
I've seen around the net that it's fairly easy to make a spot welder from a micro wave transformer /micro oven transformer.
So I was thinking if it's possibly to use the same idea to make a induction furnace?

I would like to use it for melting/ casting aluminum (...and possibly metals with a higher melting point... if possible)

any idea if it's possible.. and how to?

ok, I'll try to look for it :)
is there another way i can use the MOT (micro oven transformer) for melting aluminum.
ive seen: "the metal melter" instructable/ video; https://www.instructables.com/id/METAL-MELTER/

and thought I might be able to use the same idea...

I was thinking I maybe could connect both electrodes/ wires (+ and -)
to each end of the aluminum "bar" and it would melt. And then "just" put both electrodes/ wires down into the molten aluminum and it would produce heat enough to melt other parts of aluminum plunged into the aluminum that is already molten at that point?...

what do you think of that idea?

No, an induction furnace is operated at very high frequencies - and their transformers are made of exotic materials that can handle them.

There is an excellent instructable on induction heating, if you search for it.
