Low effort furnace.

    I came across this video showing a furnace that was made from fire bricks stacked up from the floor. If you were only going to use this furnace once or twice a year it would make sense not to go to all the trouble to build a proper furnace. I also like his idea of using the lift out tongs to pour as well as lift the crucible out.

    FINALLY! Someone using the word SMELT correctly! Nice melt. Gold... purdy!

    That was a pretty cool gold melt. It would've been a lot cooler if there wasn't all the pitting. I'm a little interested in what he got for value.

    So if I smelt my swarf, it also turns to gold? :)

    I get the point of the OP. The principles are really pretty basic.
    The wisdom involved in the subject of the video might be a different matter....

    He's not smelting, just melting gold flake.
    Have you noticed on Gold Rush they are using Devil Forge furnaces to make ingots out of their booty.

    I looked up as to what smelt means, To heat up a metal ore to change it to a metal. So what the video showed was dirty gold being melted with flux to clean the metal.

    Smelting = reducing a metal from its ore.
    Melting = transition a solid metal (or any meltable substance) to a liquid

    His furnace design is much the same as mine, except mine has an angle-iron frame securing the walls and the lid. The burner on mine is bolted underneath and originally heated a cast-iron plumbers pot and nowadays a crucible.

    This a good cheap way to make a furnace for beginners, especially if melting aluminium. Disadvantage is no swirl around a circular pot, or crucible, when the walls are square,

    It always amazes me that the persons who melt gold make a low effort furnace and most people here melt low value metals make very elaborate furnaces. Have a look at the video at the 1:49 mark.

    This is how it works. My brother in law uses a 10buck crucible and a torch.
