Where can I get talc for strengthening the mold?Is the talc added only to the silica powder (200 mesh) and plaster slip coat? Or is talc also added to the silica sand (80 mesh) and plaster outer mixture. I do use chicken wire to reinforce the mold and this helps reduce the size of cracks.
Also, can cat litter be used as grog?
Thanks, Joe from Wisconsin

talc
I only use talc for the first layer or to make up part of the sculpture if I am encasing it in glass. It does not strengthen. It makes the mixture softer and smoother, I think.
I get talc from STANDRED CERAMIC in Pittsburgh. Any ceramic supply store.
