Made face cast but looks like the top half of the face has collapsed!!! why????? or how????

Question

i made a face cast using slow setting alginate and then modroc on top of that once it had started setting.

however while i was putting on the last of the modoc my model started to say it felt really heavy above his eyes and as though it had all of a sudden collapsed. he actually started to panic me as he started getting nervous cos it felt so heavy and meant he struggled to breathe!!!!!!

when i took the mould of and cast from it using plaster it did look like the top of the face had almost collapsed a little bit. does anyone know how or what i could do next time to stop this happening????

also not alot of detail was picked up. although i followed the instructions on the algiate pack do you think it would be better if next time i made it slightly thinner???? and was slow setting alginate the best thing to use????

any tips appreciated.

thanks alot

Answer 1

Did it get lumps in it?

Was it mixed to the right consistency?  

What about putting straws up the model's nose to make sure their airways are open? Is that a possibility?  

There are lots of demonstration videos on youtube - I'd have a look at some of these before you start again.
