I attached the syringe and two smaller tubes on the object and made the second half of the mold. Here i also made the mistake of not spraying the hairspray so the result of the mold was one big block of silicone. So i had to cut the mold in half to open it up and take the Minion figure out for the second try.
The result was that two halves of the mold were stuck together.
MOLD MAKING (2ND TRY)
Re-do of mold making starting with the object embedded in clay. Ready for silicone to be poured in.
This time I remembered to mark the registry hole before I put the silicone mold in for the first half.
The holes in the back of the object were covered by hot glue. I attached the syringe and two smaller tubes again. I also remembered to put hairspray on before I poured the second half of the silicone mold.
Even when I put hairspray on before the second half the mold, the silicone was stuck together again. I cut the edges of the halfline mark on the block of silicone and started to rip it apart hoping it opens up exactly where I made half and half molds. Fortunately it came very close to that so I went ahead to fill the object void with liquid plastic.
CASTING (1ST TRY)
First try in casting came out only two-thirds of the object. It seems like liquid plastic didn't fill up all the way also because it was curing really fast compared to the amount that was poured in through the syringe. There are also issues with not having a vent hole closer to top of the mold which could be another reason the liquid plastic didn't fill up all the way.
CASTING (2ND TRY)
For the second try for casting, I added one more vent hole to accommodate for the large void that was created in the first try. Second cast came out better than the first, but it still didn't fill up all the way and has two voids as well as bubbles.
CASTING (3RD TRY)
Third try in casting came out the best out of three trys. I added two more vent holes where there were voids for the second cast and it filled up all the way. However, there seemed to be more bubbles as I add more vent holes.
