Watching this be done has clarified many things for me, especially since the articles I read seemed to have left out parts of the process. Thank you for the video.
@iToasterman Reasons for heating the resulting shell: 1) to eliminate the wax 2) to "fire" the shell & harden it into a ceramic like material, hence the name "ceramic shell." Shells are usually allowed to cool after this firing, then reheated for later pouring. 3) This re-heating is to allow the metal to flow better since the shell dissipates heat rather quickly causing metal to freeze before filling the mold, resulting in big gaps. (an edited version of a response from sculptor Tuck Langland)
The slurry for ceramic shell casting is called colloidal silica, which is a complex mixture, the exact recipes for which are generally held by the various companies making it.
@TheMedievalMan and knowing led me to finish a clay sculpture, called a foundry and had my first bronze sculpture made. I was awstruck with the tour of the foundry in person. WOW I posted a video of the sculpture
