Hi. I'm working on a prop for a short film, which involves life-casting a
head and torso. The finished piece will ideally be hollow rubber.. I'm
thinking latex.. I don't have the facilities to make or bake foam latex.
The cast head will be torn open down the front, with a puppet creature
inside (not torn on screen, the prop itself is already torn) similar to
in the concept drawing here. I'm having a hard time figuring out the
best way to cast the head in latex though.. Can I cast latex by building
up layers directly from into an alginate mold? Or would we need to use
silicone for the mold? Any suggestions for building up some
shape/strength in the latex would be helpful too, as I know that it will
end up being fairly floppy. (in some places that will work, ie: where
it's tearing open in the face.
Any help would be amazing.
Thanks so much.
