Moulding my Prop
To create my prop, I looked at images of fat and fat replicas at an anatomical level, and decided to sculpt the patty layer on one side, and the flesh layer on th eopposing side. To mould this, I decided to create a two aprt mould usinf wet clay as the wall. This would then have a pigmented silicone skin painted inside the two part mould, and filled with a cheaper, felxible material such as gelatine, so I still have realistic movement in the piece.
The opposing side was textured to look like skin. So using the 'X' methos I created a realistic skin texture and added in some subtle pores on top of cling film. This helped to stop any clay balling up and to keep the lines smooth without any rough edges.
It was dificult to find reference for my sculpt. Ideally I wanted to create textures from existing organic materials to help speed up the process, alternatively, I enusred I looked at a wide variety of fatty textures to recreate an appropriate sculpt.
Using Le beau touche, i created lumps and crevices to give a fatty impression. I then added subtle veiny textures in betweent he lumps, which can then be painted once ran in silicone.
I built up a wet clay wall about half way up the sculpt. Thi was then released using PVA, which I built up in 3 ayers and left to dry before applying my gel coat for fibreglassing.
Two Part Mould
This image shows an example of a two part mould. Tis is made into two using a wall of water based (WED) clay which helps to stop fibreglass resin being inhibited after it is released using PVA. Once one side is moulded, the clay wall is removed and the opposite is moulded in the same way, except it is moulded against the existing mould you did first.
