This clay model is a bit smaller than the life size. It is made of WED clay. The model is dry by now and is ready for making a mold for casting. Before applying coats of silicone for making a soft mold, I need to spray this sculpture with this release agent. This spray will prevent silicone from sticking to the model for good. It is better to use this spray outdoors because fumes will be all over the place. The release agent is fully dry by now. It covers the entire head sculpture in a very thin and shiny film. Instead of a release spray it is also possible to use some technical vaseline, which is much cheaper. For a soft mold, I will use this multi-purpose white silicone. It is the cheapest I could find. I have to say that the purpose of this exercise is to test if it is possible to make a sculpture casting with very cheap materials that are not designed for art. Previously, I was using proper silicones, casting resins and other professional grade art materials for casting. Such materials are very expensive. So, I decided to test if cheap stuff would be any good for sculpting. I know that this silicone is very flexible and resistant to breaking. When it’s dry, it can be stretched four times of its original size without any damage. This is very good. However, I also know that this silicone shrinks in size when it dries. This might be a real problem. This is what I want to test. How much a soft silicone mold will reduce in size and would it affect the appearance of a casted head?
