Copper's melting point is 1,982 degrees Fahrenheit. Assuming you have a stove capable of exceeding that temperature, you can melt copper on your stove to use in castings for fishing bobbers or other decorative pieces in your home. Many propane stoves can reach temperatures in excess of the melting point for copper.
Place the cast iron skillet onto the burner and turn the burner on to full heat. Heat the skillet for a period of 15 to 20 minutes to allow time for the skillet to heat up.
Place small copper pieces into the skillet. Use pieces such as cut up copper sheeting. Place a lid onto the skillet.
Stir the copper as it starts to soften to help keep it mixed. Check the copper every few minutes and stir it until it completely liquefies.
