Choosing a gas furnace for pouring copper & occasional silver bars...

[universalcurrency]

Hi all

I have a fairly large collection of scrap copper and would like to pour some bars, however the facility I am using has no electric so I am limited to gas or at a push charcoal.  Can anyone recommend a furnace and/or go through factors on selecting a suitable capacity?  Also what kit will I need including safety gear?  I already have a brazing hearth as a start and some snips but that about all...

these use gas and seem to be pretty good....

I have a Devil Forge and it works really well.

A crucible to melt the metal.

Mold to pour your copper into.

Crucible tongs to lift and pour.

Good thick gloves and face protection.

A metal skimmer to skim off the dross/slag.

Propane tank to power the forge.

 

If you need more details let me know.

Hello, this is off topic but don't want to create a new thread for this question. 

Is there any benefits of turning scrap metal into shot first before melting again for the final product? The main reason I ask is that I see a lot of shot being sold on eBay rather than scrap.

What metals are we talking about?

 Tin, just got a little project going on. Was just trying to work out if I put scrap through the shot making progress first, does it add any benefits other than making it faster to melt.

Apart from it being purer Id guess not. For scrap metal its probably not worth the time or effort to turn into shot first.
