i was thinking about this earlier today, and just now realized i have no clue, and this is probably the best place to ask.
i have some silicone caulk, never really opened, for a prop bomb i was going to build out of plexiglass.
i have a small mold i want to make, one piece, and i vaguely recall something about using this stuff in a book i read about mold making.
so.... any tips/tricks/ideas/etc for this?
by small mold i mean maybe something around 3" long, by about 1" wide by about 1/2" thick. i just need a one shot casting out of it.
again, any tips or instructions would be greatly appreciated about this. i dont recall this ever being mentioned in a thread anywhere, but i do remember it in a molding/casting book (same guy who did the mask making book). just not sure what kinda silicone stuff i gotta have, and if i gotta put some kinda release agent on the thing im molding, or what.
