Because of the plastics 2-4 minute cure time I had to work fast. For a novice this was difficult to get used to both mixing and pouring in 2-4 minutes while trying to avoid air bubbles.
I wouldnt say i was able to perfect the craft however  with some trial and error I was able to turn out a complete figure.
If I were to do this again knowing the speed of the resins curing I think I would be able to deal with working at speed.

Once all the molds had fully cured I was able to start casting, stetting up for casting was easy, using safety precautions such as gloves and a mask. Then taking the mold and securing it tight shut with elastic bands before mixing the 2part resin liquid.

At this point I had to rectify the holes that were left to pour the liquid, they were much too small and wouldnt let the liquid flow in or the air to get out.

The final parts going under the silicon where the body and legs, another 48hrs (both halves) of waiting would have been long enough. however the mold for the legs split and so after restoration took and extra 8 to cure.

 After waiting a further 24hrs for the larger molds to cure (48hrs total) the silicon is ready to be removed from the clay.
For first time molds the end result is strong. The head has casted in full detail and there are no airbubbles that can ruin any of the molds.
The only problem I have faced with the silicon is that it will pick up the most minute detail, so I can already tell the final model will feature imperfections.
retrospectively i should have spent more time perfect the figure and even choosing a better material to sculpt around the styrofoam.

The rig/ set up for the model to be set in were made from clay as it was strong enough to hold its shape and soft enough to mold into place. The model part is then set halfway down in the clay so you will only be casting half the mold.
To help the mold hold together once both sides are casted I have used small pegs which will create joins in the mold later on.
because of size and space I can only mold 2 parts at a time (head/ arms). This is something that will slow down the process especially with the 24 hour curing time.
This is something I would like to rectify if i were to do the project again and look for a silicone with a shorter curing period.

 The spray primer was applied twice and lightly sanded between coats to try and make the finish as smooth as possible ready to be casted.
The head was difficult to spray because of the deep crevasses where the eyes and brow are supposed to be. Once primed the clay becomes less porous and should be better at holding up against the silicone mixture that has to cure for 12-14 hours per half mold.
