alginate is an idea.
I still think that plaster is a very danger idea, even you have a hammer.
I'll rather you pour a lot of water before it set if anything happen.
The thing about alginate is they shrink within half an hour if you put too
much water on before or after it set.
And it is like a very soft rubber, so you still need plaster as a backing.
Make sure you have two little holes with straw for your model to breath.
Alginate is so good & detail and at the same time remind your model that
some hair might come off.
Pour in plaster to duplicate from your mould is recommanded to do right the
way after mould is set.
Recommanded plaster will be Plaster of paris from USG .Which is a fast
setting plaster. & the final mold will be Pottery No1 Plaster. 100
Water-140Plaster Mixed by weight.
alginate can find in all Hospital supply.
