Did you use your refractory all the way up to the metal shell or did you put a layer of insulation around it such as perlite. Ive herd that some people just use a layer of refractory like 2 inches thick and then insulate around that with perlite. The foundry im working on is right about the same size as yours, will have a 10inch diameter hole. Any help or advise will be greatly appreciated. thanks

My refractory is about 1' thick with a layer of vermiculite insulation around it. (If I had it to do over again, I think I'd use "real" insulation.

[GeneT45]

No! Someone has probably done it and survived, but odds are good that the pot would break spilling molten metal everywhere.

[GeneT45]

The skimmer I use is just steel. It will melt if it's in the pot too long, but just for scraping off the slag it's OK. If you mean some kind of ladle, you'd want to line it with refractory - like a sand/fireclay mixture.

yeah i need a cup too can't find them what are the made of and what are they where can i get one

[GeneT45]

I use clay-graphite "Super Salamander" crucibles that come pre-annealed. I got mine at progresstool.

Nice rig. @doctoroblivion. You can't melt titanium in these furnaces with out a certin atmosphere. Its normally done in a vacuum induction furnace

[BrimstoneMerc]

Ebay has plenty of vendors selling Salamnder Crucibles.

Where can I get a Super Salamander crucible? Progress Tools went belly up. The company that took them over at least the website has crucibles but I don't know if they are the same thing. I sent them an email but I have to wait for a reply. Some times email isn't fast enough.

Nice job- thank you for making this video. Casting iron/steel is considered to be "the" home challenge. Lot of difference between 1200 for aluminum vs 2300 for steel

was this lpg fired?

[mynameismatt2010]

@ba470 the 'poy' he poured the metal out of is called a crucible and you can buy them from most science stores, or online tool vendors.

[havocdaemon]

Very controlled pour! Nicely done

[DoctorOblivian]

can this thing get hot enough (safely under normal use) to melt steel or titanium as well?

[InToonamIsLegacy]

i have those same gloves

[ba470]
