Great furnace, my 12 and 10 year put it together so easy to setup. Took a bit to get up to temp which makes sense. Only used the the bottom gas line as flames shot out 1.5 feet when both were on. Melted aluminum great. The tongs provided aren't that great ended up using long vice grips to move crucible and pour.
Very dissapointed , bought this as a xmas present for my son , we went to use it and it comes with a non compatable regulator and is not able to connect to a gas bottle here in Australia even though it is advertised on a Australian site - do NOT BUY
This is a good starter kit but before melting you should get a good set of lifting and pouring tongs. The corner of fire brick was broke but that’s nothing the crucible had a little manufacturing damage on one side but I cured it to bright orange and slow cooled in the furnace and it went thru 4 pours no issues bearly showing any use
