Leg Mould

Since it was decided that the table legs for the side table will be made out of concrete a mould had to be created. In order to do this modelling silicone was purchased in order to get all the carved details of the existing legs. Below are the pictures of the different steps it has taken to make the mould:
The original table with the can of silicone.
First the leg had to be suspended halfway deep in clay.
The silicone was mixed with a catalyst and a catalyst booster to reduce the setting time.
The silicone was poured into the mould, totally covering the leg.
Once one half was done a wall was built up again and the rest of the silicone poured.
Another was build around the silicone in order to make a plaster casing that will stop the silicone expanding when the concrete is poured in.


The Final mould is shown below:
