After casting an ear, we then moved on to casting a hand, the method for this is the same as when we cast the ear, just on a slightly bigger scale. This hand cast then can also be used to create a bespoke prosthetic and can also be used in the film and television industry. Below are some pictures of the hand cast being made along with the method.
- 2lt bottle
- Plastic sheet
- Cut the top of a bottle
- Put the bottle on a chair (put it at that height that is comfortable for the model)
- Vaseline can be applied to the hand if it is dry to give some slip
- Fill the bottle with water, about an inch or so from the top and pour into a bucket. (the bucket should be on a plastic sheet on the floor)
- Mix the alginate up (see ear casting post) and pour it into the bottle. Pour a small amount into the bottom first, and then get the model to put their hand and continue to pour the rest in.
- Let the alginate set
- Once it has set, get the model to wriggle their hand out of the alginate while you pull on the bottle to also help release the hand
- Mix up the plaster
- Pour a small amount of plaster into the alginate mould, and coat the side of the cast. Then pour in the rest if the plaster, and over the top of the alginate to create a base for the positive of the hand cast.
- Once the plaster has set, cut down the side of the plastic bottle and remove it, leaving you with the alginate and the plaster inside. Gently remove the alginate, by pealing it off little by little until you are just left with the plaster hand.
- Once the plaster hand is left with no alginate on it, it can then be filed and smoothed down to remove any lumps or bumps.
