How to Cast Copper? A Complete Guide

Cast Copper

Copper is one of the most malleable metals and has been used for centuries for jewelry making, metalworking, and other projects. So, if you’re looking to get started with copper casting, here’s a guide on how to do it.

Gather Your Materials

Before you start casting copper, make sure you have all the necessary materials. You’ll need a furnace or kiln capable of reaching extremely high temperatures (in excess of 1700 degrees Fahrenheit), safety gear including safety glasses and oven mitts, a crucible made out of either ceramic or graphite, flux (an ingredient that helps keep the molten metal from oxidizing) as well as molds made out of plaster or sand.

Prepare Your Molds & Crucibles

Once you have all your materials gathered together, it’s time to prepare your molds and crucibles. Start by heating up your molds in an oven until they reach around 300 degrees Fahrenheit. This will help ensure that the plaster or sand doesn’t absorb too much heat from the molten metal during the casting process. Then fill your crucible with flux before adding about 10-15 pounds of copper chunks into the crucible. Make sure the chunks are evenly distributed so that they melt evenly when heated up.

Start Casting!

Now that everything is prepared and ready to go, it’s time to actually start casting! Place your filled crucible into your furnace or kiln set at 1700 degrees Fahrenheit or higher—it should take around 20 minutes for the copper chunks to completely melt down into liquid form. Once the molten liquid form has been reached, let it sit in the furnace for an additional 10 minutes before pouring it into your prepared molds. Once cast in its mold, let cool until solidified. Voila! You now have successfully cast copper pieces!


Casting copper is a great way to create custom pieces for jewelry making or any other art project you might be working on, but it requires patience as well as careful preparation beforehand in order to get successful results every time. With this guide on how to cast copper, you should now be equipped with all the tools needed for a successful endeavor! Good luck!
