Man of the Future: Step 9

Hello again and thank you for joining me for this Artist’s Studio.
The next step after coating the clay sculpture with rubber mold compound, is to encase the rubber in a shell of plaster to hold its shape after the clay sculpture is removed from the inside. Hemp (yes, hemp) is dipped in plaster and laid directly on the rubber mold to create the shell or “mother mold”, which will remove by splitting like a clamshell.

The division line is marked by those big round tabs around the outside of the piece- they are where bolts will go through to hold the empty mold halves back together when pouring wax into them (I think the mold makes kind of an interesting sculpture in itself at this point). After the plaster cures hard, the mold is split open and the rubber is peeled off the sculpture in sections which now fit into the plaster shell. All remnants of clay are cleaned out and the mold is reassembled in sections for our next step of casting wax copies.
