Was: Non-functioning electric melting furnace donation
Hi Jamie,
I'm intrigued by the idea of a gas furnace for melting. Can you point me in the direction of plans to make one?
There are a couple of ways you can achieve this.
The first step is to buy, or borrow, this book :-
“Gas Burners for Forges, Furnaces and Kilns” By Porter
Mike Porter is a very nice guy and I’ve known him for many years
through backyard casting groups.
Even if you don’t choose to make the heating devices in his book you
will have enough knowledge to formulate your own working ideas.
Alternately, if you only need to melt a little metal.
I conducted an experiment many years ago, I was just testing
refractory materials. The experiment was successful, and the micro
furnace that was created is still in my tool box today. Other people
find it useful too. Sure it’s small, but that’s the point. The
crucible is a 250g crucible.
The following image shows the micro furnace :-
It’s basically a K26 with Kaowool packing.
I didn’t build the burner for this one, just simply bought a
Bernzomatic JTH-7 hose torch.
Looks like rubbish, does the job, has been doing it for a very long
time, and is extremely cheap to run.

P. S. I left it looking like rubbish so that people will understand
that you don’t need expensive equipment to start melting metal
