Moulding the Sculpture

To mould the head I have coated one side in silicone. The mould wall stops the silicone from seeping onto the back of the head which means that when the front half is done I can remove the clay wall, coat the silicone that was on the mould wall with vaseline and then pour silicone on the back half. The mould worked well as it captured a lot of detail and should make a good clear silicone cast.
