I believe you can melt the copper... just a little different than you did. 1. Make sure after heat is applied for a while that you add flux, such as Borax. Sprinkle some on the hotter metal, not when it is cold. I have heard that Borax will help lower the meeting temperature of the metal while providing protection against oxidation during the melting. 2. If you can, use bricks to reflect the heat back the crucible, or at least shield the crucible and flame from air drafts. Without a crucible, and only attempting to anneal some copper, I was able to melt and fuse stranded copper. I only was using old, used exterior house bricks as a platform and three sides. It was winter time in North Central Texas, so not hot, and probably around 40° F outside.

I've had limited success using wood as a crucible, just carbonize the surface first. I find swirl head torches are much faster and hotter, but use more gas. The tri-webbed flame is like an intermediate step between swirl heads and normal pencil tips. A silver swirl or a jumbo swirl will also use all the oxygen up in the flame and help reduce oxidation

Pouring good oxygen and hydrogen free copper is a challenge even for experienced foundrymen.Alit if guys will not pour if it is cloudy outside,because the water vapor will cause hydrogen bubbles.Some use charcoal over the melt to scavenge any free oxygen. Then you want to pour a test cock to ensure you don't have gassy metal. And because of coppers incredible conductivity,you got to out more heat into it,than is being carried away,which you found out!Keep casting!

@tammygurl64 2 жыл бұрын

This was interesting.👍 I'd love to see you redo this experiment. Here's why... I may be wrong and you probably can't melt a lot at once but I honestly believe you would have been successful IF you'd used smaller/thinner pieces or piles of copper and fluxed your crucible with Borax. I know for a fact 20 gauge copper wire will melt with a butane torch because I've made balled copper head pins for my jewelry using a butane torch (aka chef's kitchen torch). The pieces you were trying to melt were just way too thick to reach a liquidus state using your torch so maybe use bits of 20 gauge or smaller wire. As for fluxing, I just noticed you didn't flux your crucible with Borax (on camera anyway) before you started. Anyway, again... excellent demonstration!👍 I look forward to a redo if you are up for it. I'm very curious. Either way, thanks so much for sharing!! 👍😊

@dadegroot 2 жыл бұрын

I'm not entirely surprised. Copper conducts heat very well. so while you got some of it up to near melting, that heat was being pulled away to the other end of the copper and dissipating. It's why copper is used in heatsinks. You could definitely do it in a coal/coke forge, but for gas, you'll want an insulated furnace to trap the heat in.

You can actually melt it in that crucible. Not sure if anyone pointed it out in the comments but I did the same thing with alot of different metals and the common denominator is that the heat is dispersed through the bottom of the crucible aas the bottom gets hot it is also cooling down. So unless you have something on the bottom of the crucible to keep the bottom of the crucible's heat endothermic then this method is indeed useless.....I went through a lot of gas and products and sleepless nights to get to this conclusion. Hope this helps anyone reading this. 🤙🏾

@ganeapaul-marius7121 Жыл бұрын

From my experience,no and even so,i would not recommend melting copper with gas if you want to cast bronze or do some hammer work with it. I am melting bronze in my apartment kitchen using propane and a turbine (lower propane psi=lower gas consumption/lower costs) in a stainless steel foundry made by me and even so,i got lots of problems because i don't make only castings but forge cold bronze too. Copper/bronze has to be protected from air and other gases,this is why a charcoal foundry is the best (charcoal burns all the gases and oxigen,creating carbon monoxide inside the foundry). As a bronze/silver/gold smith,using propane is the worst possible way to melt metals without using borax or other methods of protecting those metals. If you have inside space or outdoor space, building a clay foundry with a turbine (like a smith's foundry) is really easy and the most efficient way to melt metals and remember,good quality casts are made with the metal protected (borax or crucible cover)
