End of Year Show: Preperation

9 Jun

Over the past week I have been working on my end of year show piece. I’m working in a group with some of the really great girls in my year so I’m excited to see the final results on Thursday.

My role within the group was to design the facial makeup and create the gill and spine prosthetics – I also collaborated with Shona on some of the details of her body-paint role. We all discussed what each of us had worked on and brought our ideas together to create a final plan we were all happy with, updating each other regularly with our progress on our Facebook group.

Today I am in Uni, creating the PlasSil moulds. I was originally going to create 3D transfers using Pro-bondo however I have realised this won’t really work as I need to use the moulds to make several pieces. So I’m going to use liquid latex. I hate using liquid latex for prosthetics; alas, needs must. I’ve been speaking to Grace McComisky about how she creates her pieces as I need to work on more substantial materials for my appliances! (PS. Anyone want to give me some make-up work so I can earn the money to BUY these materials – much appreciate 😉 )

Onwards!

Creating a Silicone/Fiberglass Mould

2 Apr

STEP ONE – CREATING THE NEGATIVE

Step one was very similar to step two: once I has bedded in my hand, added the wall and then poured the silicone into the mould I allowed it to set. Once it has set I removed the clay walls and wiped down the silicone.

I then added a gel layer, followed by the two fiberglass layers. We shall talk through these processes in Step Two.100_4701

STEP TWO – CREATING THE POSITIVE.

YOU WILL NEED

  • PPE
  • Gel Coat
  • Resin
  • Catalyst
  • Fiberglass strands
  • Small square fiberglass sheets
  • Covered board
  • Clay (to stabilise mould)
  • 2x Paper cups (plastic will melt)
  • 2x Wooden mixing sticks
  • 2x Disposable brushes

METHOD

  1. Remove hand and clay from inside the Fiberglass/Silicone Negative – use water to wet the clay. You may need to remove the Outer Fiberglass shell to enable the silicone to be peeled away from the hand. Clean out the silicone mould – then sturdy horizontally with clay pieces.

  2. Mix together the gel coat and catalyst, ensuring through mixing. Coat the silicone in this with a disposable brush, ensuring there are no bubbles being trapped in the mould. This should only be a coating, not a full layer. Make sue edges are neat and all areas are covered. Then add fiberglass stands to strengthen this and ensure the fiberglass mat fuses properly.100_4711
  3. We then add the first fiberglass matt layer. After an hour, once it has “gone green” we cut the excess away and apply our second fiberglass matt layer (as second image). Once this has dried, we have our fiberglass positive and we are ready to start sculpting!
