I have been working on the
cast of my chest today to make a positive cast from it. I did this by scrubbing
soft soap into the original cast and cleaning this off before adding layers of
oil to it that were also removed afterwards. I then mixed water and fine
casting plaster together before dipping hemp mesh into this and applying it to
the inside of my cast. I built up 3 layers of the hemp mesh before leaving it
to dry for the weekend. The cast that I made today using the plaster and hemp
mesh will be separated from the original cast next week. It is difficult to get
the two to separate; the soap and oil that I rubbed into the cast to start off
with will help with the separation, but it can’t guarantee that one of the
casts won’t get damaged in the process. If this did happen, I would start the
process again with another body cast, but hopefully the two will separate without
problems.
As I had to leave the chest
cast to dry I made a cast of my hands today as well. I made the cast using dyed
green wax, shown in the top photo. The finger tips were then pierced with wire
so that when I poured a mixture of water and fine casting plaster into the wax cast
the air wouldn’t get trapped inside and stop the mixture from reaching the
finger tips. This does mean that there are small holes in the cast’s finger
nails but overall I am happy with the cast as it’s so detailed that even the
texture of the skin and a vein can be seen. The two photos of it show different sides of the same cast.
