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.

The best way I have found for using the Shellspen ceramic shell system, and pour cups. Is to not put your cup on the end of your sprue. Instead coat your sculpture and sprue system completely, dipping the entire piece into the slurry. Leaving a stub where your cup will be. Also at the same time your start slurry coating, slurry coat a circular dixie cup, on the outside only. (Dixie cups, like the ones your find with those water bottle systems everywhere, they also make a larger size Dixie cup which works great!) When you've completed all your slurry coats, and your ready to de-wax, simply take a coarse blade hacksaw, and/or a small grinder, and grind off the end the sprue stub, (to where the wax is exposed), where your pour cup will go. Then take your Dixie cup, remove the paper cup from the inside, ( the side you did'nt coat ), and match up the size of the sprue it will be attached to. And cut, or grind off the end of the cup, ( now in ceramic shell ). Then de-wax the the scupture and the cup, unattached. After de-waxing, set up your sculpture in your pre-heat
