This instructable is based on the two links below and was put together to test the durability of the gelatine prosthetic, how to glue the prosthetic in place and also to test how make-up adhered to the gelatine. It enabled me to learn by making a few mistakes which I have shown and also re-use the gelatine once clear of makeup and glue to keep the cost down when practising prosthetic construction and application.
Is a very low cost gelatine prosthetic. The entire cost was approximately 5 euros. It is less likely to cause any skin irritation if you are allergic to rubber latex as there is less surface area covered in latex apart from the edges of the bald cap but still do all the usual tests with the materials to check for allergies prior to application.
The whole process takes about an 2 hours once you are used to applying basic prosthetics and you can re-use your negative mould multiple times as the gelatine washes out easily, as long as your Plaster of Paris mix is strong. Normal ratio is Plaster of paris 2 parts to 1 part water. Simple plastic cups are the best way to measure amounts required.
The most important part of any prosthetic is to ensure you have thin edges for effective blending to the skin. This example is a little rough and needed more blending with regards to the makeup application and edges of the gelatine but it was done just to show the process and less emphasis was put on realism but it's still fairly effective and hope it gives you the basic idea.
Please be aware: Gelatine is extremely hot when melted (like hot toffee) therefore please don't apply it directly to the skin or you may create a permanent special effect prosthetic.
