Prosthetics - The final image/assessment!

Image
The time has finally come to create the final image. To begin, it is important to prepare the model. This includes giving them a cape to wear to protect their clothing, tying up their hair so it isn't in the way or in preparation for a wig and ensuring they aren't currently wearing any makeup. The skin should be cleansed with a mild skin cleanser to make sure there isn't any build up of oils on the skin as this could affect the makeup or adhesion of the prosthetics once they have been applied.  Once this step has been completed, the makeup can begin. The first thing to be applied were the eye prosthetics. This was done first as the mouth piece would make it impossible to talk and eat once applied, which would become quite uncomfortable, so this was left until the end for the model's comfort. Each eye piece was held up to the face to ensure the correct placement, with a light eyeshadow being used to trace around the edge. The eyebrows had also been glued down with an Elm

Flat Moulds: This was the first time the student had attempted running a flat mould. This mould had been made to add some extra details to the final design. Eject-It spray had been applied before three layers of alcohol based cap-plastic were applied. 20g of silicone was made, 5g of part A and B of platsil gel 10, and 10g of Smiths prosthetic deadener. Multiple issues arose with this first run. The silicone did not fully set, and it seemed that maybe the cap-plastic hadn't been applied thoroughly as the silicone appeared to have bonded to the mould. This did ruin this mould. Figure 1 - First flat mould after silicone poured in (Brown, J. 2021) Figure 2 - First flat mould after silicone had set (Brown, J. 2021) Luckily, the original sculpt was still intact so this was remoulded in silicone. Figure 3 - New flat mould (Brown, J. 2021) By this point, the cap-plastic had been changed to the acetone based, after having experimented with the snap moulds. Greater care was also being taken

Mouth piece: The first piece attempted was the mouth. Alcohol based cap-plastic was applied to both parts of the mould in three layers. Platsil gel 25 was used, and as the clay for the sculpt weighed 20g, this was the starting point for how much silicone to use. Part A and B were 5g each, and 10g of LV deadener was used. This wasn't enough to fill the whole piece, however it did pick up the detail which is a good sign. Figure 1 - Mouth piece (Brown, J. 2021) Figure 2 - Mouth piece (Brown, J. 2021) The second attempt for the mouth piece went better, however it was still not great. This time 32g was made, 8g of A and B, 16g of deadener. With three layers of alcohol cap-plastic. The full piece had picked up, however, the cap-plastic grabbed onto the excess silicone but not to the actual piece. In an effort to salvage it, three coats of cap-plastic were brushed onto the back before it was removed from the mould. This did work, however there was no cutting edge around the prosthetic, me
