In order to create a prosthetic appliance a cast needs to be made of area on which you wish to work on.
The following steps are how I did this.
You will need the following
- Bald cap/ swim cap
- Fast set Alginate
- Mod Rock Bandage
- Plaster of Paris
- Protective clothing for the model and yourself
- Vaseline
- 2 bowls ( alginate and mod rock and then re use for plaster.)
- A partner to work with.
Cover your models hair with either the swim cap or bald cap,
coat his/her brows, lashes or any remaining bits of hair anywhere with Vaseline to stop it sticking to the alginate.
once mixed, the alginate sets in 3 minutes, work quickly,
ensure you read the manufacturers instructions as this may differ, ensure you use cold water or it will immediately set.
as you can see I am working with a second person to ensure that my models airways are kept clear and it is a quick process.
once the alginate is covering all the area you need it to be applied to, begin applying the bandage, once again work with a partner, so whilst one is applying the other is checking all is OK with the model and the bandage is cut and prepared.
allow to set for around 10 min. then ask the model to suck their cheeks in and move their features about this will unlock the cast from the face, then you and your assistant carefully remove the cast by getting your model to tip slightly forward.
prior to this last stage I filled the nose holes in with some alginate,
then began filling it with plaster, ensure you coat it in areas of fine detail to capture this, it is worth mentioning that you do this with the alginate over the eyes and mouth, to capture detail.
to remove the alginate from the cast you carefully peel and it should come away with ease, there will however be areas where alginare needs picking out with sculpting tools.
Here I am removing the alginare that had embedded itself, with a sculpt tool
READY TO BE SCULPTED ON!
