Excellent information thanks.

Any ideas on how long it takes to set?

I may be able to get two molds off before she thaws out too much?

I like that it is flexible though that will be a god send.

I was trying to figure out how to get the bottom and top.

I thought I would put the medium a few inches deep in a container, set her in, push her down about an inch. Lay a layer of wax paper (or something) between the layers, then pour the rest of the mixture over.

That way I can get a complete body cast, but still be able to get the layers apart without having to cut in and risk damaging it, or damaging the subject.

Thanks,
Bruce
