Greetings - Has anyone here adapted ceramic shell casting to a jewelry casting environment? If so I would like to try it in lieu of investment casting. I would appreciate it if someone knowledgeable could share the formula for the ceramic slurry and the process for building up the shell/mold. I also plan on making a seperate crucible and attaching it to the shell, with the metal inside, so that I can heat and cast the unit in one process. Thank you.
