First Cast Gone Wrong....

So, the next stage was to place the 3 sections of the plaster jacket together and fix them together tightly with a rubber tie. I then was able to fit the silicone mold in to the jacket, tucking the sticking-out bits (such as the legs and wings) in to their indents. I decided that plaster would be the best material to try first as it was the quickest and easiest, and that way I could see how successful my casts would be and if there were any leaks in the silicone or plaster jacket. As Andy, from casting, poured my thick plaster mix in to the mold, I created a 'splash' layer, using my hand to coat all the inside surfaces of the silicone before it filled up completely.

After waiting 45 minutes, I came back and we attempted to remove the plaster jackets. It took quite a while because of the sticking-out details of the turkey and the fact that they were embedded in the jacket. Eventually, we managed to pull them all off with the help of a screwdriver. However, to my disappointment, the plaster had crumbled in the legs and the wings of the cast. I could feel it through the silicone. Andy said it would be a good idea to leave the plaster cast inside to bulk it out, and add more layers of thicksotropic silicone to those areas to make them more of a full shape, which would support them more. I also decided to use a scalpel to slice off the wings and silicone over them.
