life casting part 2

With the mould back together i used mod roc to keep it sealed. i mixed up some casting plaster and poured it in then sloshed it around with my hand to get it into all the areas, but i had forgot to plug the nose so i quickly used some clay to block the holes, but this mistake effected the cast and the nose came out distorted the clay must have pushed the alginate in. also there were several large air holes but over all the detail was very good especially around the eyes.

the left cheek area of the cast also come out distorted as can be seen in the picture below and will have to be built up a bit using chavant, i will resculpt the nose a little using photos and measurements of Rowen as reference.


all holes were plug with chavant, bumps removed and the cast cleaned up.


the back of the head was rasped down to the correct measurements taken from Rowen, it was then sanded smooth with wet sand paper, holes were drilled along the hair line and around the ear this will come out in the mould and fiber glass cast for when i sculpt the prosthetic.
the life cast is secured to a board sealed with shellac, screws drilled in at an angle then mod roc wrapped around them, screws were then drilled into the base of the head cast to length of 20 mm.
so far everything has run smoothly and attaching the head cast to the board went without any problems, i mixed up some plaster and placed it on the board around the outline of the base of the life cast and the mod roc, then it was cleaned up and the back of the head was painted with shellac to seal the plaster for moulding.
