if any where does the slag go and what metal do i use for iron or steel ingots

[EJRhees]

@dogbone222

The slag floats to the top and should be skimmed off before you pour.

I don't understand the second part to your question.

Thank you

@dogbone222

The mold for pouring Iron or steel would need to be a sand based mold, oil bonded or "green" sand.

He's making a joke. Minecraft is a video game in which you can build things, he's relating your smelting to it.

That all sounds good. I wonder if you are heating the copper so fast that the crucible is still "cold" and sucks the heat out of the copper so it re-solidifies. try heating it more slowly.

@EJRhees we melt copper pipe cuttings and wire that have been cut to around an inch in length, and we melt copper in a carbon or ceramic crucible. when attempting to pour we preheat a carbon or steel ingot mold. does this help?

@infinus5

What are you melting the Copper in?

What amount of Copper are you melting?

Maybe you need to heat it slower?

@EJRhees

at school we have been useing pure copper collected from a local scrap yard. we also use an oxy acetylene torch at around full blast. the highest temp that we get the torch to liquifies steel in around 1 min. the copper we have tried to melt liquefies and than hardens before we can pore. we have also tried an induction heater but that caused a small explosion from built up gases

Thank you for the compliment

Thank you for watching and for posting a comment.

Some Copper will vaporize, but nominal near melting point. I pour at about 100 degrees F over melting point. It could be that you're not quite reaching melting point, or that you have a lot of junk in your stock. Once you reach melting point give it 10 - 15 minutes to be more fluid, then make sure to skim the dross.

I hope this helps, let me know if you have more questions.

Thank you for watching and your question.

THe outer shell of the furnace is an old propane tank.
