Need to melt my copper.

Then you don't have time to deal with hoarding scrap copper.

 

If you have access to scrap copper wire etc. and don't mind storing it till you have enough it does mount up. Copper wire takes close to a 70% hit in value if it is not stripped and it's a right pain to strip it so no matter how you obtain it other then stealing copper pipe it's not a get rich scheme. I had a friend that worked on the line for over 30 years for a car manufacturer and saved the spot welder tips that were to short to use and filled 2 55 gallon drums now that was worth the effort.

 

It's honestly not too difficult to make yourself a furnace. All it takes for a very basic one is a small hole, some clay, wood, and an air source. You can also make one using an old propane tank.

Also, steel has a much higher melting point than copper, so you can melt copper on top of steel and have the steel still maintain its solid form.

The problem with a crucible is that you'd still need an ingot mold to pour the molten copper into after you've melted it down. You can buy crucibles online for pretty cheap. Molds can range anywhere from just a hole you dug into the dirt to cast molds you can use. Dirt actually works great, but you're going to get some impurities in there, obviously.

 

Thanks for the info. Would I get impurities from the steel?
