How can I make a mould??
I used to wonder whether or not silicone was really a plastic because it felt more like a rubber. That was when I bothered to look up what silicone actually was.
Silicone belongs to a class of synthetic materials which are polymers with a chemical structure based on chains of alternate silicon and oxygen atoms, with organic groups attached to the silicon atoms. Such compounds are typically resistant to chemical attack and insensitive to temperature changes and are used to make rubber and plastics and in polishes and lubricants. (info 2014 from Wikipedia)

| In this image I am placing down the images that I want to create moulds from. |
 |
| Here I have started mixing up the plaster with the water; layering the plaster up first until it is the same thickness as the water and then I started mixing it. The chemical reaction in the plaster itself caused it to start heating up as soon as the plaster and water mixed thoroughly. |
 |
| Here I have poured the plaster over the objects to be moulded. The plaster should be left for about half an hour to an hour for it to dry out properly and then you can move it. |
