The saga of bronze casting at Eagle Bronze continues.
After the wax molds are sprued, another mold is created. (If you were wondering, this is the final mold. We're getting close to actually casting bronze.)
This mold is ceramic and is formed by dipping the wax mold into a sand or silica slurry. As was the case with the latex coating at the beginning of the process, there are multiple coats, with different textures of slurry for each one.
Remember the fan and gloves that started this whole story? They're used in this step of the process. The molds need to dry completely between coats of slurry, and the fans help with that.
