Q: Roughly how long or how much use can I get out of a 20lb propane tank?

BTU's per gallon of propane (91,500) * Gallons of Propane in 20 pound cylinder (3.89) = 355,935 BTU's per cylinder. Burner is rated at 80,000 BTU's = 4.4492 Hours per cylinder at "full blast" Gives you 4 Hours : 26 Minutes : 57 Seconds.

Q: How long would it take to melt 5kg of copper

Depends on what youre putting in. Something with a lot of impurities that will give you lots of slag to scrape will take you a while to get that 5kg crucible full of relatively pure copper. Also, what form is the material you are melting? 5 kilos of fine wire or mesh will melt faster than a big chunk. In my experience using this for brass (slightly lower temp melting point than copper), I was able to melt, flux, and scrape dross from a full 5 kilo crucible in maybe half an hour or 40 minutes. The furnace itself reaches well over copper's melting point, so I dont imagune copper would take much longer than brass. Keep in mind I'm not an expert, tgis is just my experience.

Q: Why can’t I get this furnace hot enough to melt copper? This is my fifth attempt?

I set the regulator to 0.12 MPa, the ball valve full open and the burner disc about 1/2 inch open. For more heat you can raise the pressure on the regulator or open the burner disc more. I also coated the inside of the furnace wool with a refractory coating.(just search for foundry refractory coating.)

Q: Could this be used with a small crucible for melting a few ounces of silver or bronze? Or, is there a smaller system available? Thanks!

Yes, as long as the crucible can fit into the chamber you can use whatever size.
