What do you need to melt copper

This is how you can melt copper

Copper is a very old metal that has been processed and melted for many thousands of years. In the following article you will find out what properties copper has in melting and casting and how you can make use of them.

Copper is a popular non-ferrous metal

The Copper Age began after the Neolithic and since then the metal has been very popular and has a great influence on us humans, as it is used and built in a variety of ways. The Bronze Age that followed could no longer do without copper. That is why copper is still one of the most popular non-ferrous metals today.

Copper can be melted and poured

Like bronze, copper can be melted and poured and can therefore be used in many ways. Copper can be processed better than aluminum, which reacts very violently during the melting and casting process, i.e. when it gets hot. After melting and casting, you can further process copper as follows:

  • welding and soldering
  • polishing and grinding
  • patinate and thus make old

Prepare copper for melting

Before you begin, you need to make some preparations. The first thing you need is a smelting furnace that can provide the necessary 1086 ° Celsius heat that copper needs to melt. Such a melting furnace is available from specialist retailers, please follow the manufacturer's instructions when using it. Of course, if you have small pieces of copper, these can be melted faster than large pieces. Therefore, the trade also offers copper pellets that are specially manufactured for smelting. But you can also shred copper yourself, for example by sawing or cutting.

The next steps in melting and pouring

The first thing you need to think about your own safety when melting is because the heat is great. Toxic fumes could also escape during the process. Therefore, always wear protective glasses, gloves and heat-resistant clothing. You should also keep in mind that the quality of the copper could suffer for the following reasons:

  • For private purposes, copper usually does not meet the DIN EN values
  • old copper can be alloyed or unalloyed
  • The ability of copper to weld can suffer
  • for example if the alloy contains lead
  • Then, when pouring and cooling, there is a multiphase copper
  • this unfortunately loses many of the good properties of copper

Make molds yourself

You can also make the molds for your molten copper yourself. To do this, you need oily molding sand, which is used to create a negative impression. Then assemble both molds on top of each other. Here you pour the liquid copper, let it cool and solidify and then you can remove the part from the mold. Then the sculpture or what you have poured is only cleaned. Then you can use the techniques to either keep the copper shiny or to give it a patina.
