This was nothing I had ever seen or worked with before; liquid plastic. It didn't smell but it was gooey awful stuff and hard to manage. Shell-Shock is what it is called and it dries hard in just a few minutes and becomes very hard and brittle over time.
Small amounts are mixed in disposable cups and applied with a brush or stick. The brushes will harden after about 15 minutes so many disposable and cheap brushes and small paint sticks are needed. It can be poured and that is what I did to make the casts.
There is another type of goop that is more fun to work with. It's called Body Double and is less toxic and like rubber. It's a two part mix as well and is applied directly to the skin to create a mask or mold. It dries fast to a flexible rubbery substance.
Then a coat of medical plaster and gauze is applied to make a form that hardens over the rubber. The plaster will serve as a support for the rubber mold and help it to keep the shape when the liquid plastic is poured into the mold.
Once the cast was completed you could see the fine detail in the fingers. The mold turned out beautifully and Emily's arms and hands looked just like her.
The entire sculpture needed to be completely covered with the goop. This is what would make it impervious to moisture and the outdoor elements. After applying about an 1/8 inch over the entire surface the sanding began.
