The Sculpture
Preparing the sculpture;
The first step was to cut the cup to make a guard for the silicone.
I then had used fixing spray on the sculpture and petrolese, spraying it about 20cm away from the sculpture.
Then I put the cut cup over the sculpture and used a glue gun to seal it in place to ensure that no silicone will leak out.
Mixing the silicones;
I obtained a clean cup and covered the scales and working surface with cling film. I then had to ensure I had clean gloves and mixing sticks as it is important not to contaminate the silicones.
Because my sculpture is small, I used 30g of each silicone and ensured that I slowly added the silicones to the cup using the designated mixing sticks.
I then mixed the silicones with a clean stick, tapping out the air bubbles.
I then poured the silicones over the sculpture, ensuring it was fully covered by going back and forth over the sculpture.
For the mould to fully dry, I waited 1 hour.
Casting from the silicone mould;
Firstly, I cleaned the mould with alcohol (isopropyl) using cotton pads and cotton buds.
I then had to make a mixture of Baldiez and isopropyl, with the ratio 1:2. I then mixed it well, tapping out the air bubbles.
I sprayed the mould with petrolese and poured the mixture on to the mould. I then used a brush to distribute it over the wound, not filling the wound completely. The mixture will dry matte.
I then mixed 8g of silicone A and 8g of silicone B, using the same process as before. I then added 60% of 16g of deadener to give the silicone piece a flesh-like texture.
I then chose the appropriate pigments and added two drops of the flesh-toned one and one drop of a white pigment.
After the pigment was well mixed in, I poured a little bit of the mixture at a time and evening it out with a metal scraper tool.
Again, it takes 1 hour to dry.
