I started by creating a base and a thin wall around the kit pieces i was to cast with plasticine. This was however too dry and hard to work with; so i used it as a foundation to add clay too giving it more support. Once they had enough support they were filled with a two part silicone mix; these were left to settle and harden over night.
When i returned to the workshop the following morning the silicone had hardened and i peeled it out of the clay to reveal the moulds i will be using to cast in. i gave them a clean over as best as possible before hand so their was as little clay as possible interfering with the casting.
I mixed two-part Biresin (fast cast resin), in equal amounts and then poured it into the moulds i had previously created. these were left for around half an hour to harden. once hardened i removed them form the mould and this was the result; as you can see they retained a lot of detail and came out quite clearly. The mould are still ready for use, and the castings are nice and strong.
