How to Melt Copper With a Torch

Copper, with a melting point of 1,981 degrees Fahrenheit, can be melted using an acetylene torch. Because the activity involves high temperatures and open flame, take appropriate safety precautions, including wearing safety gear and working in a well-ventilated environment that minimizes any risk of starting a fire. Copper transfers heat rapidly, so use a crucible that will help contain the heat and minimize losses of copper flecks to the surrounding environment.

Things You'll Need

Acetylene torch
Crucible
Gloves
Safety glasses

Instructions

- 1
  Put on appropriate safety gear, including gloves, heavy clothing and safety glasses or goggles.
- 2
  Place the copper in a clean, dry crucible. It's important to melt the copper in a container to avoid loss of material and to keep hot molten copper from getting away in a manner that could be hazardous. A crucible has an appropriate shape and can withstand high temperatures. Crucibles designed for melting metals can be sourced through most suppliers of metal refining or jewelry equipment.
- 3
  Direct the flame of the acetylene torch onto the copper. Use care, as sudden movement can cause lighter copper flecks or pieces to blow away under the force of the flame.
- 4
  Hold the flame on the copper until it has melted. The time it takes to melt the copper is a function of the intensity of the flame and the thickness of the copper.
