Silicone Castings

Finally got around to casting the first batch of eyebrows, lashes, teeth, eyeballs... to test out all those moulds. The first attempt failed because the silicone was too viscous to seep into those tiny moulds using gravity alone. So for the second attempt I used a syringe to inject the silicone into the moulds. That worked really well but resulted in silicone being pushed into the gaps between the moulds so there was a lot of excess material that needed to be trimmed off afterwards. 

Turns out cutting the excess material off is quite tricky with tiny, soft shapes like that. Not a very exact process at all. Will need to find a way to optimize this at some point. The teeth also have the seams in unfortunate places so might need to redesign that mould at some point to get it perfect.

For now though I'll proceed with the face mould so I can put it all together.
