I have used the same quantity of silicone for both pieces as I used on the headpiece. The first coat was placed in the air
vacuum to remove bubbles within the mixture. As I applied this coat towards the end of the day, I did not use thixatropic or accelerator within the first coat of silicone.
As with the headpiece, a clay wall is built around the area to be moulded. As the plaster bust sticks out from it's
foam base, I had to build up the back to allow the wall to be raised up above the height of the shoulder piece sculpt. This is
neatened up to ensure an even height around the piece and keys are cut out.
