1) Seeing as the little bird mask sculpt didn't have a flat back to it, I had to cast it by means of a two part mould. I began this by finding a container that would fit the sculpt whilst still accommodating enough room on every side so the silicone wouldn't be too weak. I then filled half the container, in this case a small ramekin glass, with air dry clay and buried half the sculpt in this making sure it was air tight. Silicone was then poured over the remaining half of the sculpt that was left exposed, and left to set.
2) On taking out this half of the set silicone after the going off time, I accidentally pushed the tool I was using for leverage in getting the mould out of the container, into the sculpt itself. Because of this a little repair work was needed between casting. I also took this opportunity to trim down the silicone to fit back into the same container; it had a rim to it, so needed to be cut back down to size.
3) The second half of the mould after it had been cast: Quite a bad mould really, with a lot of airbubbles, but in no place they couldn't be simply sanded quickly away once the mask piece was cast so I saw no reason to completely re-cast this half. This half of the mould is also a slightly darker green; I put more catalyst in so it would go off a little faster this time.
4) The resin cast straight out of the mould pieces! It worked! My next step will be sanding down the edges that were left where the two mould pieces met.
