After producing the face cast a silicon mould will be made the reason for this is by having a silicone mould of the original cast it is possible to replicate it multiple times. The type of silicon used was 'tin silicon' which is typically used for mould making, an important aspect to keep in mind whilst handling this product is that it is not skin safe (wear protective gloves). Before going into detail about the silicon stage, preparation for this stage will be discussed aided by images.
Clay was placed and smoothed around the edges of the cast to secure, level and to prevent flashing/ overflow. Next as displayed in the image below a clean, smooth, level band of clay has been put around the cast. With keys placed in the clay, what a keys are will be explained later on in this process.
A 'wall' has been built for safety during the silicon stage, what I mean by this is the wall will prevent the silicone from running off the cast onto the counter top making a mess wasting product. When making the wall in question make sure that the clay at least a cm in width and inch in height.
The next step will be using silicon but that will be discussed in a separate post to prevent this post from being too long and will break up the amount of information I am giving.
