To know more about the process, here is a step-by-step guide on the bronze casting process.
The first step in making a bronze cast has a design. If you’re an artist, you can give your design to a foundry of your choice. Most foundries also have artists.

The lost-wax casting process starts by making the mold. The wax is then poured to create the gating system. Then, ceramic mold creation follows.
The wax melts and drains away before pouring the bronze and leaving it to cool.
Then remove the shell, and now you have a piece. Interestingly, “de-vesting” is the process of removing the ceramic shells in revealing the actual casting’.
The next step is sanding and polishing to an amazing patina the piece to amplify its texture. Next, sand-blasting removes particles of ceramic shells that might be left on the work. This helps in ensuring that people are able to see every detail of the piece.
For large pieces, castings are made in separate parts and are put together through welding. After assembling them, the whole piece is chased and cleaned. Then, it follows the final step of sanding, polishing, and applying the patina.
