Making a New Burner for the Furnace

Thanks for that, one of the better designs that I have seen, have you thought about adding ceramic blanket to the outside of the bricks to increase efficiency? Might need a bigger bucket though.

How long does it take to heat up before you can start melting aluminium?

I considered some Kaowool but I'm super paranoid about fibrous materials like that when they aren't encapsulated, so I'm not planning to use any anytime soon.

I should have timed how long it takes to get to melting temperature (I will next time), but a rough estimate was it took about 15 minutes with the old Harbor Freight torch, and less than 5 minutes with the new burner.
