Casting Blob: Hands, Crocs & Legs

On to casting! 

To start we need colour,

I measured out the amount of oil paint needed on some scales to ensure if I needed more I knew the exact amount of green and white needed to get my colour.

Green and white oil paint is used to colour the silicone, which I got from an art shop close to were I live. 

Unfortunately the silicone I used was a very cream coloured silicone which meant getting the green I wanted proved tricky, with me adding a lot more oil paint in to the silicone than I wanted!!

Hands

Once I got my colour, I started with the hands. I painted in a thin layer of silicone in to the mould, and allowed that to cure before casting the arm. 

This is done to ensure I have a layer of cured silicone in the mould before casting. This helps with limiting the amount of air bubbles you get in a cast, and also when putting the armature in for casting, you can be assured that the armature will not be to close to the finished cast, as a barrier of silicone is already cured beforehand. 

If that makes any sense! 

I then placed my armature inside, poured silicone in, and clamped the mould together and waited!

These are how the cast hands came out, I was happy with them and went to take the seam lines off!

This is were it didn't go so well! I tried to remove the seam lines with small scissors to start, and then move on to a dremel. 

Unfortunately, be it the type of silicone, the amount of paint I added or my terrible craftsmanship, the silicone began to rip, I then had to stop with the seam lines and keep them how they were. Hopfully on camera the tears won't be visible.   

Legs

The Legs were very simple and quick to cast, with not much to say!

I began by filling up both halves of the mould with silicone, as a K+S hole was on the top of the mould this ensure the armature went in straight. 

Once they were cast, they slid out easily!

Crocs

The same process was applied to the croc as the hand casts. Silicone was painted in, once that had cured, the armature was put in the mould. Silicone was then poured in and I then closed and clamped the mould and waited.

I was nervous with opening this cast as I didn't know if the holes in the croc would work, or snap once i removed the croc. 

I opened the mould to see the sole of the croc worked nicely! I then prayed the top looked as good!

The croc was removed easily and the inverted holes in the crocs turned out great! Which I was very happy with!

With the croc finished I could now move on to the casting of the bands. 

These were simply poured in to the mould and left. Once cured, I could peel them out, clean up the edges with a scalpel and they were then stuck on to the croc with dots of silicone acting as super glue, as silicone sticks to itself very well.
