Body Casting
Manual
Casting the plaster
With a paint brush, paint a
thin layer of plaster on the inside of the mold. At first it will be
very liquid, run down the walls and puddle at the bottom of the mold.
It will soon become creamier and heavier.
You will not be filling up
your mold with plaster to the brim. You will construct instead a
layer 3 cm thick ( 1 1/3 in) on the entire inside surface of the
mold. You can use the plastic bowl to pour large amounts and then
spread it around and push it against the walls with the brush.

n Plaster
that has just started to set and no longer runs, can be made to
run again by shaking or vibrating it.

If the edges of the plaster
cast are untidy, you can smooth them with a wet sponge but I
recommend that you do not interfere with freshly poured plaster. Let
it set and do any cleaning and finishing required afterwards. Let it
set for 3 to 4 hours or more before attempting to unmold, preferably
overnight.

nYou
can use some other specialised materials instead of plaster. I
nevertheless would recommend that you use plain Plaster of Paris
for your first attempt and only use more expensive materials
once you are familiar with the casting process.
