During the wax burn-out, the ceramic shell which encases the sprewed wax panelis put in a furnace. The wax is melted or "lost" as it escapes and drains away.
The French name cire perdue or "lost wax" bronze casting derives its
name from this step in the process.
Below, notice the spout or trough that emerges from the furnace: As the wax begins to melt inside the ceramic shell, it drips out into a bucket and momentarily catches fire.
