Yes this is how they make prosthetic masks.
Thank you, i did'nt want to ruin both my latex and my alginate ^^ i'd give it a try as soon as i get my alginate ^^. by the way do you know how much time does it take for the latex to dry?
Too many variables to comment - It is dry when it is touch dry although it will continue to looses water over the next day or so unless you artificially heat it to dry it out.
thank you for your advice, i now hope i won't need a releasing agent ^^
May be of interest to you.
