As to how think I'd say a half inch minimum but not more than two inches.
A plaster mother mold sould work but a fiberglass one would be lighter and easyier to work with.

NEW! MoldGel SILFREE. A revolutionary formula.
Made with all food-grade ingredients. It nourishes
the earth when discarded. 3-to-1 mix ratio yields
twice the volume as those 1-to-1 brands. Delayed
shrinkage for delayed casting - so creamy smooth, too.

Polyurethane molds:--
I was just hoping someone could help me with a rubber mold I am making. I have a
perfect pregnancy casting with a perfect arm and hand and want to make a
permanent mold of it.
Firstl, I bought this stuff about a year ago and I think the person who sold it
to me gave me the wrong stuff, it is for pour over mold in a container, but if
you add something to it you can brush it on. well I'm not that patcient to wait
until tomorrow and drive 30 min to get it.
So I set up my casting and mixed my first batch, after most of it dripped off, I
found that if I let it cure a little it stays where I want it to.
My question is
How thick should I make the rubber mold and can anyone tell me the best way to
make the mother mould, I fugure if I make sure all the undercuts are filled I
can just make a detachable gypsum mother mold.
Any tips would be very helpfull.
Thanks for your time
Diane
