I just hope that you were facing the sculpt when sneezing to achieve this :raiseeybrow

Re: Removing a Silicone Mold from a Sculpt:
Quote: When you say "peel off", do you almost turn the silicone inside out?
Exactly.
You could even scoop out some clay to make more room as well,if you can get in there. Your original sculpt will probably get messed up anyway,whether you slice a seam down the back or not,just because of the ears,etc.
If it were a bust of just a typical human head that was going to be cast in resin,a slice up the back would be standard,and it would usually just slide off with little to no damage to the original.
What you're trying to do is produce a seamless copy,obviously,but with a very awkwardly shaped piece,so your challenges are greater than normal.
I have very little experience with this,but I've actually only used Plasti Paste,and I like it. It doesn't get any easier to use,it's light and very strong,but again,I really have nothing to compare it to.
Anyway,nice piece and I'm sure it will work out. :wink

Thanks John! This is the first time I've worked with any of these materials, and I'll be honest, it's a bit intimidating. Especially when you factor in the time and money spent on it, lol. Good to see you here again bro! :cheers

Re: Removing a Silicone Mold from a Sculpt:
I've never used the rebound silicone before but I know with mold max they say to let the mold air out for at least 24 hours if you are going to run urethane so all the alcohol evaporates out of the the silicone ...failing to do so will result in an uncured casting...trust me, learned this the hard way :doh

Ah man, good thing you told me! I would've never known! Thanks Shawn. I'm hoping to have the plasti-paste jacket done tomorrow.
