So, I should probably explain what my project is before asking my question. I'm making a model of King Kong, I'm still working on the skull, but I eventually want to sculpt on top of it with clay and then make a silicon mold of that head. The below photo gives you an idea of size.
I want to keep the costs down as much as possible, so I was wondering about the logistics of making a brush on mold for something this size, using a jacket of plaster of paris or similar material. I'm going to make separate molds for the teeth, and once I finish sculpting the head, I'll block out the mouth with clay--so the head will be a relatively simple shape. I'm thinking a one part mold where I just pull out the head with a two part jacket, and then making a slush casting that I can later reinforce. But since I don't have a lot of experience with mold making, I'd like to know what others think. Thanks!
