More Mould Making

 

A few stages further on and each silicone rubber half mould is encased within plaster.

There are keys within it to hold the mould in place.

The silicone took overnight to set but the plaster is much quicker so before long I had 3 mould waiting for wax.

The Week at SSW

 A whole 5 days of learning mould making!

First of all, it was to make sure a silicone release agent was applied liberally to the sculptures - I really wanted the sculptures to come out from the silcone after it had set.

Next, lay on top of cling film to protect the plaster from the clay, and build up around the piece about halfway, following any lines (so that the mould lines when cast show as little as possible)

a clay wall is added and then the silicone poured in.

I'm glad I had 3 pieces as I could practice and repeat the process 3 times to learn it more thoroughly.
